Constructor & Destructor Documentation

◆ Collider()

+ +
+
+ + + + + + + + + + + + + + + + + + +
Collider (const VecView< const Box > & leafBB,
const VecView< const uint32_t > & leafMorton 
)
+
+

Creates a Bounding Volume Hierarchy (BVH) from an input set of axis-aligned bounding boxes and corresponding Morton codes. It is assumed these vectors are already sorted by increasing Morton code.

+ +
+
+

Member Function Documentation

+ +

◆ Transform()

+ +
+
+ + + + + + + + +
bool Transform (glm::mat4x3 transform)
+
+

Apply axis-aligned transform to all bounding boxes. If transform is not axis-aligned, abort and return false to indicate recalculation is necessary.

+ +
+
+ +

◆ UpdateBoxes()

+ +
+
+ + + + + + + + +
void UpdateBoxes (const VecView< const Box > & leafBB)
+
+

Recalculate the collider's internal bounding boxes without changing the hierarchy.

+ +
+
+ +

◆ Collisions()

+ +
+
+
+template<const bool selfCollision, const bool inverted, typename T >
+ + + + + + + + +
template SparseIndices Collisions< false, true, Box > (const VecView< const T > & queriesIn) const
+
+

For a vector of query objects, this returns a sparse array of overlaps between the queries and the bounding boxes of the collider. Queries are normally axis-aligned bounding boxes. Points can also be used, and this case overlaps are defined as lying in the XY projection of the bounding box. If the query vector is the leaf vector, set selfCollision to true, which will then not report any collisions between an index and itself.

Detailed Description

+

Two-dimensional cross sections guaranteed to be without self-intersections, or overlaps between polygons (from construction onwards). This class makes use of the Clipper2 library for polygon clipping (boolean) and offsetting operations.

+

Member Enumeration Documentation

+ +

◆ FillRule

+ +
+
+ + + + + +
+ + + + +
enum class FillRule
+ 		+strong
+
+

Filling rules defining which polygon sub-regions are considered to be inside a given polygon, and which sub-regions will not (based on winding numbers). See the Clipper2 docs for a detailed explaination with illusrations.

+ + + + + +
Enumerator
EvenOdd 

Only odd numbered sub-regions are filled.

+
NonZero 

Only non-zero sub-regions are filled.

+
Positive 

Only sub-regions with winding counts > 0 are filled.

+
Negative 

Only sub-regions with winding counts < 0 are filled.

+
+ +
+
+ +

◆ JoinType

+ +
+
+ + + + + +
+ + + + +
enum class JoinType
+ 		+strong
+
+

Specifies the treatment of path/contour joins (corners) when offseting CrossSections. See the Clipper2 doc for illustrations.

+ + + + +
Enumerator
Square 

Squaring is applied uniformly at all joins where the internal join angle is less that 90 degrees. The squared edge will be at exactly the offset distance from the join vertex.

+
Round 

Rounding is applied to all joins that have convex external angles, and it maintains the exact offset distance from the join vertex.

+
Miter 

There's a necessary limit to mitered joins (to avoid narrow angled joins producing excessively long and narrow spikes). So where mitered joins would exceed a given maximum miter distance (relative to the offset distance), these are 'squared' instead.

+
+ +
+
+

Constructor & Destructor Documentation

+ +

◆ CrossSection() [1/5]

+ +
+
+ + + + + + + +
CrossSection ()
+
+

The default constructor is an empty cross-section (containing no contours).

+ +
+
+ +

◆ CrossSection() [2/5]

+ +
+
+ + + + + + + + +
CrossSection (const CrossSection & other)
+
+

The copy constructor avoids copying the underlying paths vector (sharing with its parent via shared_ptr), however subsequent transformations, and their application will not be shared. It is generally recommended to avoid this, opting instead to simply create CrossSections with the available const methods.

+ +
+
+ +

◆ CrossSection() [3/5]

+ +
+
+ + + + + + + + + + + + + + + + + + +
CrossSection (const SimplePolygon & contour,
FillRule fillrule = FillRule::Positive 
)
+
+

Create a 2d cross-section from a single contour. A boolean union operation (with Positive filling rule by default) is performed to ensure the resulting CrossSection is free of self-intersections.

+
Parameters
+ + + +
contourA closed path outlining the desired cross-section.
fillruleThe filling rule used to interpret polygon sub-regions created by self-intersections in contour.
+
+
+ +
+
+ +

◆ CrossSection() [4/5]

+ +
+
+ + + + + + + + + + + + + + + + + + +
CrossSection (const Polygons & contours,
FillRule fillrule = FillRule::Positive 
)
+
+

Create a 2d cross-section from a set of contours (complex polygons). A boolean union operation (with Positive filling rule by default) is performed to combine overlapping polygons and ensure the resulting CrossSection is free of intersections.

+
Parameters
+ + + +
contoursA set of closed paths describing zero or more complex polygons.
fillruleThe filling rule used to interpret polygon sub-regions in contours.
+
+
+ +
+
+ +

◆ CrossSection() [5/5]

+ +
+
+ + + + + + + + +
CrossSection (const Rect & rect)
+
+

Create a 2d cross-section from an axis-aligned rectangle (bounding box).

+
Parameters
+ + +
rectAn axis-aligned rectangular bounding box.
+
+
+ +
+
+

)
+ 		+static
+
+

Constructs a circle of a given radius.

+

Returns the axis-aligned bounding rectangle of all the CrossSections' vertices.

+ +
+
+ +

◆ Translate()

+ +
+
+ + + + + + + + +
CrossSection Translate (const glm::vec2 v) const
+
+

Move this CrossSection in space. This operation can be chained. Transforms are combined and applied lazily.

+
Parameters
+ + +
vThe vector to add to every vertex.
+
+
+ +
+
+ +

◆ Rotate()

+ +
+
+ + + + + + + + +
CrossSection Rotate (float degrees) const
+
+

Applies a (Z-axis) rotation to the CrossSection, in degrees. This operation can be chained. Transforms are combined and applied lazily.

+
Parameters
+ + +
degreesdegrees about the Z-axis to rotate.
+
+
+ +
+
+ +

◆ Scale()

+ +
+
+ + + + + + + + +
CrossSection Scale (const glm::vec2 scale) const
+
+

Scale this CrossSection in space. This operation can be chained. Transforms are combined and applied lazily.

+
Parameters
+ + +
vThe vector to multiply every vertex by per component.
+
+
+ +
+
+ +

◆ Mirror()

+ +
+
+ + + + + + + + +
CrossSection Mirror (const glm::vec2 ax) const
+
+

Mirror this CrossSection over the arbitrary axis described by the unit form of the given vector. If the length of the vector is zero, an empty CrossSection is returned. This operation can be chained. Transforms are combined and applied lazily.

+
Parameters
+ + +
axthe axis to be mirrored over
+
+
+ +
+
+ +

◆ Transform()

+ +
+
+ + + + + + + + +
CrossSection Transform (const glm::mat3x2 & m) const
+
+

Transform this CrossSection in space. The first two columns form a 2x2 matrix transform and the last is a translation vector. This operation can be chained. Transforms are combined and applied lazily.

+
Parameters
+ + +
mThe affine transform matrix to apply to all the vertices.
+
+
+ +
+
+ +

◆ Warp()

+ +
+
+ + + + + + + + +
CrossSection Warp (std::function< void(glm::vec2 &)> warpFunc) const
+
+

Move the vertices of this CrossSection (creating a new one) according to any arbitrary input function, followed by a union operation (with a Positive fill rule) that ensures any introduced intersections are not included in the result.

+
Parameters
+ + +
warpFuncA function that modifies a given vertex position.
+
+
+ +
+
+ +

◆ WarpBatch()

+ +
+
+ + + + + + + + +
CrossSection WarpBatch (std::function< void(VecView< glm::vec2 >)> warpFunc) const
+
+

Same as CrossSection::Warp but calls warpFunc with a VecView which is roughly equivalent to std::span pointing to all vec2 elements to be modified in-place

+
Parameters
+ + +
warpFuncA function that modifies multiple vertex positions.
+
+
+ +
+
+ +

◆ Simplify()

+ +
+
+ + + + + + + + +
CrossSection Simplify (double epsilon = 1e-6) const
+
+

Remove vertices from the contours in this CrossSection that are less than the specified distance epsilon from an imaginary line that passes through its two adjacent vertices. Near duplicate vertices and collinear points will be removed at lower epsilons, with elimination of line segments becoming increasingly aggressive with larger epsilons.

+

It is recommended to apply this function following Offset, in order to clean up any spurious tiny line segments introduced that do not improve quality in any meaningful way. This is particularly important if further offseting operations are to be performed, which would compound the issue.

+ +
+
+ +

◆ Offset()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
CrossSection Offset (double delta,
JoinType jointype,
double miter_limit = 2.0,
int circularSegments = 0 
) const
+
+

Inflate the contours in CrossSection by the specified delta, handling corners according to the given JoinType.

+
Parameters
+ + + + + +
deltaPositive deltas will cause the expansion of outlining contours to expand, and retraction of inner (hole) contours. Negative deltas will have the opposite effect.
jtThe join type specifying the treatment of contour joins (corners).
miter_limitThe maximum distance in multiples of delta that vertices can be offset from their original positions with before squaring is applied, when the join type is Miter (default is 2, which is the minimum allowed). See the Clipper2 MiterLimit page for a visual example.
circularSegmentsNumber of segments per 360 degrees of JoinType::Round corners (roughly, the number of vertices that will be added to each contour). Default is calculated by the static Quality defaults according to the radius.
+
+
+ +
+
+ +

◆ Boolean()

+ +
+
+ + + + + + + + + + + + + + + + + + +
CrossSection Boolean (const CrossSection & second,
OpType op 
) const
+
+

Perform the given boolean operation between this and another CrossSection.

+ +
+
+ +

◆ BatchBoolean()

+ +
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + +
CrossSection BatchBoolean (const std::vector< CrossSection > & crossSections,
OpType op 
)
+ 		+static
+
+

Perform the given boolean operation on a list of CrossSections. In case of Subtract, all CrossSections in the tail are differenced from the head.

+ +
+
+ +

◆ operator+()

+ +
+
+ + + + + + + + +
CrossSection operator+ (const CrossSection & Q) const
+
+

Compute the boolean union between two cross-sections.

+ +
+
+ +

+
+

Compute the boolean difference of a (clip) cross-section from another (subject).

+ +
+
+ +

◆ operator-=()

+ +
+
+ + + + + + + + +
CrossSection & operator-= (const CrossSection & Q)
+
+

Compute the boolean difference of a (clip) cross-section from a another (subject), assigning the result to the subject.

+ +
+
+ +

◆ operator^()

+ +
+
+ + + + + + + + +
CrossSection operator^ (const CrossSection & Q) const
+
+

Compute the boolean intersection between two cross-sections.

Detailed Description

+

This library's internal representation of an oriented, 2-manifold, triangle mesh - a simple boundary-representation of a solid object. Use this class to store and operate on solids, and use MeshGL for input and output, or potentially Mesh if only basic geometry is required.

+

In addition to storing geometric data, a Manifold can also store an arbitrary number of vertex properties. These could be anything, e.g. normals, UV coordinates, colors, etc, but this library is completely agnostic. All properties are merely float values indexed by channel number. It is up to the user to associate channel numbers with meaning.

+

Manifold allows vertex properties to be shared for efficient storage, or to have multiple property verts associated with a single geometric vertex, allowing sudden property changes, e.g. at Boolean intersections, without sacrificing manifoldness.

+

Manifolds also keep track of their relationships to their inputs, via OriginalIDs and the faceIDs and transforms accessible through MeshGL. This allows object-level properties to be re-associated with the output after many operations, particularly useful for materials. Since separate object's properties are not mixed, there is no requirement that channels have consistent meaning between different inputs.

+

Constructor & Destructor Documentation

+ +

◆ Manifold() [1/3]

+ +
+
+ + + + + + + +
Manifold ()
+
+

Construct an empty Manifold.

+ +
+
+ +

◆ Manifold() [2/3]

+ +
+
+ + + + + + + + + + + + + + + + + + +
Manifold (const MeshGL & meshGL,
const std::vector< float > & propertyTolerance = {} 
)
+
+

Convert a MeshGL into a Manifold, retaining its properties and merging only the positions according to the merge vectors. Will return an empty Manifold and set an Error Status if the result is not an oriented 2-manifold. Will collapse degenerate triangles and unnecessary vertices.

+

All fields are read, making this structure suitable for a lossless round-trip of data from GetMeshGL. For multi-material input, use ReserveIDs to set a unique originalID for each material, and sort the materials into triangle runs.

+
Parameters
+ + + +
meshGLThe input MeshGL.
propertyToleranceA vector of precision values for each property beyond position. If specified, the propertyTolerance vector must have size = numProp - 3. This is the amount of interpolation error allowed before two neighboring triangles are considered to be on a property boundary edge. Property boundary edges will be retained across operations even if the triangles are coplanar. Defaults to 1e-5, which works well for most properties in the [-1, 1] range.
+
+
+ +
+
+ +

◆ Manifold() [3/3]

+ +
+
+ + + + + + + + +
Manifold (const Mesh & mesh)
+
+

Convert a Mesh into a Manifold. Will return an empty Manifold and set an Error Status if the Mesh is not an oriented 2-manifold. Will collapse degenerate triangles and unnecessary vertices.

+
Parameters
+ + +
meshThe input Mesh.
+
+
+ +
+
+

◆ Smooth() [1/2]

+ +
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + +
Manifold Smooth (const MeshGL & meshGL,
const std::vector< Smoothness > & sharpenedEdges = {} 
)
+ 		+static
+
+

Constructs a smooth version of the input mesh by creating tangents; this method will throw if you have supplied tangents with your mesh already. The actual triangle resolution is unchanged; use the Refine() method to interpolate to a higher-resolution curve.

+

By default, every edge is calculated for maximum smoothness (very much approximately), attempting to minimize the maximum mean Curvature magnitude. No higher-order derivatives are considered, as the interpolation is independent per triangle, only sharing constraints on their boundaries.

+
Parameters
+ + + +
meshGLinput MeshGL.
sharpenedEdgesIf desired, you can supply a vector of sharpened halfedges, which should in general be a small subset of all halfedges. Order of entries doesn't matter, as each one specifies the desired smoothness (between zero and one, with one the default for all unspecified halfedges) and the halfedge index (3 * triangle index + [0,1,2] where 0 is the edge between triVert 0 and 1, etc).
+
+
+

At a smoothness value of zero, a sharp crease is made. The smoothness is interpolated along each edge, so the specified value should be thought of as an average. Where exactly two sharpened edges meet at a vertex, their tangents are rotated to be colinear so that the sharpened edge can be continuous. Vertices with only one sharpened edge are completely smooth, allowing sharpened edges to smoothly vanish at termination. A single vertex can be sharpened by sharping all edges that are incident on it, allowing cones to be formed.

+ +
+
+ +

◆ Smooth() [2/2]

+ +
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + +
Manifold Smooth (const Mesh & mesh,
const std::vector< Smoothness > & sharpenedEdges = {} 
)
+ 		+static
+
+

Constructs a smooth version of the input mesh by creating tangents; this method will throw if you have supplied tangents with your mesh already. The actual triangle resolution is unchanged; use the Refine() method to interpolate to a higher-resolution curve.

+

By default, every edge is calculated for maximum smoothness (very much approximately), attempting to minimize the maximum mean Curvature magnitude. No higher-order derivatives are considered, as the interpolation is independent per triangle, only sharing constraints on their boundaries.

+
Parameters
+ + + +
meshinput Mesh.
sharpenedEdgesIf desired, you can supply a vector of sharpened halfedges, which should in general be a small subset of all halfedges. Order of entries doesn't matter, as each one specifies the desired smoothness (between zero and one, with one the default for all unspecified halfedges) and the halfedge index (3 * triangle index + [0,1,2] where 0 is the edge between triVert 0 and 1, etc).
+
+
+

At a smoothness value of zero, a sharp crease is made. The smoothness is interpolated along each edge, so the specified value should be thought of as an average. Where exactly two sharpened edges meet at a vertex, their tangents are rotated to be colinear so that the sharpened edge can be continuous. Vertices with only one sharpened edge are completely smooth, allowing sharpened edges to smoothly vanish at termination. A single vertex can be sharpened by sharping all edges that are incident on it, allowing cones to be formed.

+ +
+
+ +

◆ Tetrahedron()

+ +
+
+ + + + + +
+ + + + + + + +
Manifold Tetrahedron ()
+ 		+static
+
+

Constructs a tetrahedron centered at the origin with one vertex at (1,1,1) and the rest at similarly symmetric points.

+ +
+
+ +

◆ Cube()

+ +
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + +
Manifold Cube (glm::vec3 size = glm::vec3(1.0f),
bool center = false 
)
+ 		+static
+
+

Constructs a unit cube (edge lengths all one), by default in the first octant, touching the origin. If any dimensions in size are negative, or if all are zero, an empty Manifold will be returned.

+
Parameters
+ + + +
sizeThe X, Y, and Z dimensions of the box.
centerSet to true to shift the center to the origin.
+
+
+ +
+
+ +

◆ Cylinder()

+ +
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Manifold Cylinder (float height,
float radiusLow,
float radiusHigh = -1.0f,
int circularSegments = 0,
bool center = false 
)
+ 		+static
+
+

A convenience constructor for the common case of extruding a circle. Can also form cones if both radii are specified.

+
Parameters
+ + + + + + +
heightZ-extent
radiusLowRadius of bottom circle. Must be positive.
radiusHighRadius of top circle. Can equal zero. Default is equal to radiusLow.
circularSegmentsHow many line segments to use around the circle. Default is calculated by the static Defaults.
centerSet to true to shift the center to the origin. Default is origin at the bottom.
+
+
+ +
+
+ +

◆ Sphere()

+ +
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + +
Manifold Sphere (float radius,
int circularSegments = 0 
)
+ 		+static
+
+

Constructs a geodesic sphere of a given radius.

+
Parameters
+ + + +
radiusRadius of the sphere. Must be positive.
circularSegmentsNumber of segments along its diameter. This number will always be rounded up to the nearest factor of four, as this sphere is constructed by refining an octahedron. This means there are a circle of vertices on all three of the axis planes. Default is calculated by the static Defaults.
+
+
+ +
+
+ +

◆ Extrude()

+ +
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Manifold Extrude (const CrossSection & crossSection,
float height,
int nDivisions = 0,
float twistDegrees = 0.0f,
glm::vec2 scaleTop = glm::vec2(1.0f) 
)
+ 		+static
+
+

Constructs a manifold from a set of polygons by extruding them along the Z-axis. Note that high twistDegrees with small nDivisions may cause self-intersection. This is not checked here and it is up to the user to choose the correct parameters.

+
Parameters
+ + + + + + +
crossSectionA set of non-overlapping polygons to extrude.
heightZ-extent of extrusion.
nDivisionsNumber of extra copies of the crossSection to insert into the shape vertically; especially useful in combination with twistDegrees to avoid interpolation artifacts. Default is none.
twistDegreesAmount to twist the top crossSection relative to the bottom, interpolated linearly for the divisions in between.
scaleTopAmount to scale the top (independently in X and Y). If the scale is {0, 0}, a pure cone is formed with only a single vertex at the top. Note that scale is applied after twist. Default {1, 1}.
+
+
+ +
+
+ +

◆ Revolve()

+ +

Manifold Revolve (const CrossSection & crossSection,
int circularSegments = 0,
float revolveDegrees = 360.0f 
)
+ 		+static
+
+

Constructs a manifold from a set of polygons by revolving this cross-section around its Y-axis and then setting this as the Z-axis of the resulting manifold. If the polygons cross the Y-axis, only the part on the positive X side is used. Geometrically valid input will result in geometrically valid output.

+
Parameters
+ + + + +
crossSectionA set of non-overlapping polygons to revolve.
circularSegmentsNumber of segments along its diameter. Default is calculated by the static Defaults.
revolveDegreesNumber of degrees to revolve. Default is 360 degrees.

+ + + + + +
+ + + + + + + + +
Manifold Compose (const std::vector< Manifold > & manifolds)
+ 		+static
+
+

Constructs a new manifold from a vector of other manifolds. This is a purely topological operation, so care should be taken to avoid creating overlapping results. It is the inverse operation of Decompose().

+
Parameters
+ + +
manifoldsA vector of Manifolds to lazy-union together.
+
+
+ +
+
+ +

◆ Decompose()

+ +
+
+ + + + + + + +
std::vector< Manifold > Decompose () const
+
+

This operation returns a vector of Manifolds that are topologically disconnected. If everything is connected, the vector is length one, containing a copy of the original. It is the inverse operation of Compose().

+ +
+
+ +

◆ GetMesh()

+ +
+
+ + + + + + + +
Mesh GetMesh () const
+
+

This returns a Mesh of simple vectors of vertices and triangles suitable for saving or other operations outside of the context of this library.

+ +
+
+ +

◆ GetMeshGL()

+ +
+
+ + + + + + + + +
MeshGL GetMeshGL (glm::ivec3 normalIdx = glm::ivec3(0)) const
+
+

The most complete output of this library, returning a MeshGL that is designed to easily push into a renderer, including all interleaved vertex properties that may have been input. It also includes relations to all the input meshes that form a part of this result and the transforms applied to each.

+
Parameters
+ + +
normalIdxIf the original MeshGL inputs that formed this manifold had properties corresponding to normal vectors, you can specify which property channels these are (x, y, z), which will cause this output MeshGL to automatically update these normals according to the applied transforms and front/back side. Each channel must be >= 3 and < numProp, and all original MeshGLs must use the same channels for their normals.
+
+
+ +
+
+ +

◆ IsEmpty()

+ +
+
+ + + + + + + +
bool IsEmpty () const
+
+

Does the Manifold have any triangles?

+ +
+
+ +

◆ Status()

+ +
+
+ + + + + + + +
Manifold::Error Status () const
+
+

Returns the reason for an input Mesh producing an empty Manifold. This Status only applies to Manifolds newly-created from an input Mesh - once they are combined into a new Manifold via operations, the status reverts to NoError, simply processing the problem mesh as empty. Likewise, empty meshes may still show NoError, for instance if they are small enough relative to their precision to be collapsed to nothing.

+ +
+
+ +

◆ NumVert()

+ +
+
+ + + + + + + +
int NumVert () const

+ +

◆ NumPropVert()

+ +
+
+ + + + + + + +
int NumPropVert () const
+
+

The number of property vertices in the Manifold. This will always be >= NumVert, as some physical vertices may be duplicated to account for different properties on different neighboring triangles.

+ +
+
+ +

◆ BoundingBox()

+ +
+
+ + + + + + + +
Box BoundingBox () const
+
+

Returns the axis-aligned bounding box of all the Manifold's vertices.

◆ Precision()

+ +
+
+ + + + + + + +
float Precision () const
+
+

Returns the precision of this Manifold's vertices, which tracks the approximate rounding error over all the transforms and operations that have led to this state. Any triangles that are colinear within this precision are considered degenerate and removed. This is the value of ε defining ε-valid.

+ +
+
+ +

◆ Genus()

+ +
+
+ + + + + + + +
int Genus () const
+
+

The genus is a topological property of the manifold, representing the number of "handles". A sphere is 0, torus 1, etc. It is only meaningful for a single mesh, so it is best to call Decompose() first.

+ +
+
+ +

◆ GetProperties()

+ +
+
+ + + + + + + +
Properties GetProperties () const
+
+

Returns the surface area and volume of the manifold.

+
+ +

◆ OriginalID()

+ +
+
+ + + + + + + +
int OriginalID () const
+
+

If this mesh is an original, this returns its meshID that can be referenced by product manifolds' MeshRelation. If this manifold is a product, this returns -1.

+ +
+
+ +

◆ AsOriginal()

+ +
+
+ + + + + + + +
Manifold AsOriginal () const
+
+

This function condenses all coplanar faces in the relation, and collapses those edges. In the process the relation to ancestor meshes is lost and this new Manifold is marked an original. Properties are preserved, so if they do not match across an edge, that edge will be kept.

+ +
+
+ +

◆ Rotate()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
Manifold Rotate (float xDegrees,
float yDegrees = 0.0f,
float zDegrees = 0.0f 
) const
+
+

Applies an Euler angle rotation to the manifold, first about the X axis, then Y, then Z, in degrees. We use degrees so that we can minimize rounding error, and eliminate it completely for any multiples of 90 degrees. Additionally, more efficient code paths are used to update the manifold when the transforms only rotate by multiples of 90 degrees. This operation can be chained. Transforms are combined and applied lazily.

+
Parameters
+ + + + +
xDegreesFirst rotation, degrees about the X-axis.
yDegreesSecond rotation, degrees about the Y-axis.
zDegreesThird rotation, degrees about the Z-axis.

+
+ + + + + + + + +
Manifold Transform (const glm::mat4x3 & m) const

+
+ +
+
+ +

◆ Mirror()

+ +
+
+ + + + + + + + +
Manifold Mirror (glm::vec3 normal) const

+
+
+ +
+
+ +

◆ Warp()

+ +
+
+ + + + + + + + +
Manifold Warp (std::function< void(glm::vec3 &)> warpFunc) const
+
+

This function does not change the topology, but allows the vertices to be moved according to any arbitrary input function. It is easy to create a function that warps a geometrically valid object into one which overlaps, but that is not checked here, so it is up to the user to choose their function with discretion.

+
Parameters
+ + +
warpFuncA function that modifies a given vertex position.
+
+
+ +
+
+ +

◆ WarpBatch()

+ +
+
+ + + + + + + + +
Manifold WarpBatch (std::function< void(VecView< glm::vec3 >)> warpFunc) const
+

+ +
+
+ +

+
+

Create a new copy of this manifold with updated vertex properties by supplying a function that takes the existing position and properties as input. You may specify any number of output properties, allowing creation and removal of channels. Note: undefined behavior will result if you read past the number of input properties or write past the number of output properties.

+
Parameters
+ + + +
numPropThe new number of properties per vertex.
propFuncA function that modifies the properties of a given vertex.
+
+
+ +
+
+ +

◆ CalculateCurvature()

+ +
+
+ + + + + + + + + + + + + + + + + + +
Manifold CalculateCurvature (int gaussianIdx,
int meanIdx 
) const
+
+

Curvature is the inverse of the radius of curvature, and signed such that positive is convex and negative is concave. There are two orthogonal principal curvatures at any point on a manifold, with one maximum and the other minimum. Gaussian curvature is their product, while mean curvature is their sum. This approximates them for every vertex and assigns them as vertex properties on the given channels.

+
Parameters
+ + + +
gaussianIdxThe property channel index in which to store the Gaussian curvature. An index < 0 will be ignored (stores nothing). The property set will be automatically expanded to include the channel index specified.
meanIdxThe property channel index in which to store the mean curvature. An index < 0 will be ignored (stores nothing). The property set will be automatically expanded to include the channel index specified.
+
+
+ +
+
+ +

◆ CalculateNormals()

+ +
+
+ + + + + + + + + + + + + + + + + + +
Manifold CalculateNormals (int normalIdx,
float minSharpAngle = 60 
) const
+
+

Fills in vertex properties for normal vectors, calculated from the mesh geometry. Flat faces composed of three or more triangles will remain flat.

+
Parameters
+ + + +
normalIdxThe property channel in which to store the X values of the normals. The X, Y, and Z channels will be sequential. The property set will be automatically expanded such that NumProp will be at least normalIdx + 3.
minSharpAngleAny edges with angles greater than this value will remain sharp, getting different normal vector properties on each side of the edge. By default, no edges are sharp and all normals are shared. With a value of zero, the model is faceted and all normals match their triangle normals, but in this case it would be better not to calculate normals at all.
+
+
+ +
+
+ +

◆ SmoothByNormals()

+ +
+
+ + + + + + + + +
Manifold SmoothByNormals (int normalIdx) const
+
+

Smooths out the Manifold by filling in the halfedgeTangent vectors. The geometry will remain unchanged until Refine or RefineToLength is called to interpolate the surface. This version uses the supplied vertex normal properties to define the tangent vectors.

+
Parameters
+ + +
normalIdxThe first property channel of the normals. NumProp must be at least normalIdx + 3. Any vertex where multiple normals exist and don't agree will result in a sharp edge.
+
+
+ +
+
+ +

◆ SmoothOut()

+ +
+
+ + + + + + + + + + + + + + + + + + +
Manifold SmoothOut (float minSharpAngle = 60,
float minSmoothness = 0 
) const
+
+

Smooths out the Manifold by filling in the halfedgeTangent vectors. The geometry will remain unchanged until Refine or RefineToLength is called to interpolate the surface. This version uses the geometry of the triangles and pseudo-normals to define the tangent vectors.

+
Parameters
+ + + +
minSharpAngledegrees, default 60. Any edges with angles greater than this value will remain sharp. The rest will be smoothed to G1 continuity, with the caveat that flat faces of three or more triangles will always remain flat. With a value of zero, the model is faceted, but in this case there is no point in smoothing.
minSmoothnessrange: 0 - 1, default 0. The smoothness applied to sharp angles. The default gives a hard edge, while values > 0 will give a small fillet on these sharp edges. A value of 1 is equivalent to a minSharpAngle of 180 - all edges will be smooth.
+
+
+ +
+
+ +

◆ Refine()

+ +
+
+ + + + + + + + +
Manifold Refine (int n) const
+
+

Increase the density of the mesh by splitting every edge into n pieces. For instance, with n = 2, each triangle will be split into 4 triangles. These will all be coplanar (and will not be immediately collapsed) unless the Mesh/Manifold has halfedgeTangents specified (e.g. from the Smooth() constructor), in which case the new vertices will be moved to the interpolated surface according to their barycentric coordinates.

+
Parameters
+ + +
nThe number of pieces to split every edge into. Must be > 1.
+
+
+ +
+
+ +

◆ RefineToLength()

+ +
+
+ + + + + + + + +
Manifold RefineToLength (float length) const
+
+

Increase the density of the mesh by splitting each edge into pieces of roughly the input length. Interior verts are added to keep the rest of the triangulation edges also of roughly the same length. If halfedgeTangents are present (e.g. from the Smooth() constructor), the new vertices will be moved to the interpolated surface according to their barycentric coordinates.

+
Parameters
+ + +
lengthThe length that edges will be broken down to.
+
+
+ +
+
+ +

+
+ + + + + + + + + + + + + + + + + + +
Manifold Boolean (const Manifold & second,

Detailed Description

+

These static properties control how circular shapes are quantized by default on construction. If circularSegments is specified, it takes precedence. If it is zero, then instead the minimum is used of the segments calculated based on edge length and angle, rounded up to the nearest multiple of four. To get numbers not divisible by four, circularSegments must be specified.

+

Member Function Documentation

+ +

◆ SetMinCircularAngle()

+ +
+
+ + + + + +
+ + + + + + + + +
static void SetMinCircularAngle (float angle)
+ 		+inlinestatic
+
+

Sets an angle constraint the default number of circular segments for the CrossSection::Circle(), Manifold::Cylinder(), Manifold::Sphere(), and Manifold::Revolve() constructors. The number of segments will be rounded up to the nearest factor of four.

+
Parameters
+ + +
angleThe minimum angle in degrees between consecutive segments. The angle will increase if the the segments hit the minimum edge length. Default is 10 degrees.
+
+
+ +
+
+ +

◆ SetMinCircularEdgeLength()

+ +
+
+ + + + + +
+ + + + + + + + +
static void SetMinCircularEdgeLength (float length)
+ 		+inlinestatic
+
+

Sets a length constraint the default number of circular segments for the CrossSection::Circle(), Manifold::Cylinder(), Manifold::Sphere(), and Manifold::Revolve() constructors. The number of segments will be rounded up to the nearest factor of four.

+
Parameters
+ + +
lengthThe minimum length of segments. The length will increase if the the segments hit the minimum angle. Default is 1.0.
+
+
+ +
+
+ +

◆ SetCircularSegments()

+ +
+
+ + + + + +
+ + + + + + + + +
static void SetCircularSegments (int number)
+ 		+inlinestatic
+
+

Sets the default number of circular segments for the CrossSection::Circle(), Manifold::Cylinder(), Manifold::Sphere(), and Manifold::Revolve() constructors. Overrides the edge length and angle constraints and sets the number of segments to exactly this value.

+
Parameters
+ + +
numberNumber of circular segments. Default is 0, meaning no constraint is applied.
+
+
+ +
+
+ +

◆ GetCircularSegments()

+ +
+
+ + + + + +
+ + + + + + + + +
static int GetCircularSegments (float radius)
+ 		+inlinestatic
+
+

Determine the result of the SetMinCircularAngle(), SetMinCircularEdgeLength(), and SetCircularSegments() defaults.

+
Parameters
+ + +
radiusFor a given radius of circle, determine how many default segments there will be.

Detailed Description

+
template<typename T>
+class manifold::VecView< T >

View for Vec, can perform offset operation. This will be invalidated when the original vector is dropped or changes length. Roughly equivalent to std::span<T> from c++20

Class Documentation

+ +

◆ manifold::Mesh

+ +
+
+ + + + +
struct manifold::Mesh
+
+

The triangle-mesh input and output of this library.

+
+ + + + + + + + + + + + + + + + +
Class Members
+vector< vec3 > +vertPos +Required: The X-Y-Z positions of all vertices.
+vector< ivec3 > +triVerts +

Required: The vertex indices of the three triangle corners in CCW (from the outside) order, for each triangle.

+
+vector< vec3 > +vertNormal +

Optional: The X-Y-Z normal vectors of each vertex. If non-empty, must have the same length as vertPos. If empty, these will be calculated automatically.

+
+vector< vec4 > +halfedgeTangent +

Optional: The X-Y-Z-W weighted tangent vectors for smooth Refine(). If non-empty, must be exactly three times as long as Mesh.triVerts. Indexed as 3 * tri + i, representing the tangent from Mesh.triVerts[tri][i] along the CCW edge. If empty, mesh is faceted.

+
+float +precision = 0 +

The absolute precision of the vertex positions, based on accrued rounding errors. When creating a Manifold, the precision used will be the maximum of this and a baseline precision from the size of the bounding box. Any edge shorter than precision may be collapsed.

+
+ +
+
+ +

◆ manifold::Smoothness

+ +
+
+ + + + +
struct manifold::Smoothness
+
+

Defines which edges to sharpen and how much for the Manifold.Smooth() constructor.

+
+ + + + + + + +
Class Members
+int +halfedge +The halfedge index = 3 * tri + i, referring to Mesh.triVerts[tri][i].
+float +smoothness +

A value between 0 and 1, where 0 is sharp and 1 is the default and the curvature is interpolated between these values. The two paired halfedges can have different values while maintaining C-1 continuity (except for 0).

+
+ +
+
+ +

◆ manifold::Properties

+ +
+
+ + + + +
struct manifold::Properties
+
+

Geometric properties of the manifold, created with Manifold.GetProperties().

+
+ + + + + + + +
Class Members
+float +surfaceArea +
+float +volume +
+ +
+
+ +

◆ manifold::SVDSet

+ +
+
+ + + + +
struct manifold::SVDSet
+
+

The three matrices of a Singular Value Decomposition.

+
+ + + + + + + + + + +
Class Members

+ +
+
+

Typedef Documentation

+ +

◆ SimplePolygon

+ +
+
+ + + + +
using SimplePolygon = std::vector<glm::vec2>
+
+

Single polygon contour, wound CCW. First and last point are implicitly connected. Should ensure all input is ε-valid.

+ +
+
+ +

◆ Polygons

+ +
+
+ + + + +
using Polygons = std::vector<SimplePolygon>
+
+

Set of polygons with holes. Order of contours is arbitrary. Can contain any depth of nested holes and any number of separate polygons. Should ensure all input is ε-valid.

+ +
+
+

Function Documentation

std::vector< glm::ivec3 > Triangulate (const Polygons & polygons,
float precision 
)
+
+ +

Triangulates a set of ε-valid polygons. If the input is not ε-valid, the triangulation may overlap, but will always return a manifold result that matches the input edge directions.

+
Parameters
+ + + +
polygonsThe set of polygons, wound CCW and representing multiple polygons and/or holes.
precisionThe value of ε, bounding the uncertainty of the input.
+
+
+
Returns
std::vector<glm::ivec3> The triangles, referencing the original polygon points in order.

+

This 4x3 matrix can be used as an input to Manifold.Transform() to turn an object. Turns along the shortest path from given up-vector to (0, 0, 1).

+
Parameters
+ + +
upThe vector to be turned to point upwards. Length does not matter.
+
+
+ +
+
+ +

◆ CCW()

◆ LevelSet()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Mesh LevelSet (std::function< float(glm::vec3)> sdf,
Box bounds,
float edgeLength,
float level,
bool canParallel 
)
+
+

Constructs a level-set Mesh from the input Signed-Distance Function (SDF). This uses a form of Marching Tetrahedra (akin to Marching Cubes, but better for manifoldness). Instead of using a cubic grid, it uses a body-centered cubic grid (two shifted cubic grids). This means if your function's interior exceeds the given bounds, you will see a kind of egg-crate shape closing off the manifold, which is due to the underlying grid.

+
Parameters
+ + + + + + +
sdfThe signed-distance functor, containing this function signature: float operator()(glm::vec3 point), which returns the signed distance of a given point in R^3. Positive values are inside, negative outside.
boundsAn axis-aligned box that defines the extent of the grid.
edgeLengthApproximate maximum edge length of the triangles in the final result. This affects grid spacing, and hence has a strong effect on performance.
levelYou can inset your Mesh by using a positive value, or outset it with a negative value.
canParallelParallel policies violate will crash language runtimes with runtime locks that expect to not be called back by unregistered threads. This allows bindings use LevelSet despite being compiled with MANIFOLD_PAR active.
+
+
+
Returns
Mesh This class does not depend on Manifold, so it just returns a Mesh, but it is guaranteed to be manifold and so can always be used as input to the Manifold constructor for further operations.

Detailed Description

+

Debugging features.

+

The features require compiler flags to be enabled. Assertions are enabled with the MANIFOLD_DEBUG flag and then controlled with ExecutionParams. Exceptions are only thrown if the MANIFOLD_EXCEPTIONS flag is set. Import and Export of 3D models is only supported with the MANIFOLD_EXPORT flag, which also requires linking in the Assimp dependency.

◆ manifold::Material

+ +
+
+ + + + +
struct manifold::Material
+
+

PBR material properties for GLB/glTF files.

+
+ + + + + + + + + + + + + + + + + + + +
Class Members
+float +roughness = 0.2 +Roughness value between 0 (shiny) and 1 (matte).
+float +metalness = 1 +Metalness value, generally either 0 (dielectric) or 1 (metal).
+vec4 +color = glm::vec4(1.0f) +

Color (RGBA) multiplier to apply to the whole mesh (each value between 0 and 1).

+
+vector< vec4 > +vertColor +

Optional: If non-empty, must match Mesh.vertPos. Provides an RGBA color for each vertex, linearly interpolated across triangles. Colors are linear, not sRGB. Only used with Mesh export, not MeshGL.

+
+ivec3 +normalChannels = glm::ivec3(-1) +

For MeshGL export, gives the property indicies where the normal channels can be found. Must be >= 3, since the first three are position.

+
+ivec4 +colorChannels = glm::ivec4(-1) +

For MeshGL export, gives the property indicies where the color channels can be found. Any index < 0 will output all 1.0 for that channel.

+
+ +
+
+ +

◆ manifold::ExportOptions

+ +
+
+ + + + +
struct manifold::ExportOptions
+
+

These options only currently affect .glb and .gltf files.

+
+ + + + + + + +
Class Members
+bool +faceted = true +

When false, vertex normals are exported, causing the mesh to appear smooth through normal interpolation.

+
+Material +mat = {} +PBR material properties.

◆ ImportMesh()

+ +
+
+ + + + + + + + + + + + + + + + + + +
Mesh ImportMesh (const std::string & filename,
bool forceCleanup 
)
+
+

Imports the given file as a Mesh structure, which can be converted to a Manifold if the mesh is a proper oriented 2-manifold. Any supported polygon format will be automatically triangulated.

+

This is a very simple import function and is intended primarily as a demonstration. Generally users of this library will need to modify this to read all the important properties for their application and set up any custom data structures.

+
Parameters
+ + + +
filenameSupports any format the Assimp library supports.
forceCleanupThis merges identical vertices, which can break manifoldness. However it is always done for STLs, as they cannot possibly be manifold without this step.
+
+
+ +
+
+ +

◆ ExportMesh() [1/2]

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
void ExportMesh (const std::string & filename,
const Mesh & mesh,
const ExportOptions & options 
)
+
+

Saves the Mesh to the desired file type, determined from the extension specified. In the case of .glb/.gltf, this will save in version 2.0.

+

This is a very simple export function and is intended primarily as a demonstration. Generally users of this library will need to modify this to write all the important properties for their application and read any custom data structures.

+
Parameters
+ + + + +
filenameThe file extension must be one that Assimp supports for export. GLB & 3MF are recommended.
meshThe mesh to export, likely from Manifold.GetMesh().
optionsThe options currently only affect an exported GLB's material. Pass {} for defaults.
+
+
+ +
+
+ +

◆ ExportMesh() [2/2]

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
void ExportMesh (const std::string & filename,
const MeshGL & mesh,
const ExportOptions & options 
)
+
+

+

This is a very simple export function and is intended primarily as a demonstration. Generally users of this library will need to modify this to write all the important properties for their application and read any custom data structures.

+
Parameters
+ + + + +
filenameThe file extension must be one that Assimp supports for export. GLB & 3MF are recommended.

◆ GetAxisAlignedProjection()

+ +
+
+ + + + + +
+ + + + + + + + +
glm::mat3x2 GetAxisAlignedProjection (glm::vec3 normal)
+ 		+inline
+
+

By using the closest axis-aligned projection to the normal instead of a projection along the normal, we avoid introducing any rounding error.

+ +
+
+ +

◆ TriangulateIdx()

+ +
+
+ + + + + + + + + + + + + + + + + + +
std::vector< glm::ivec3 > TriangulateIdx (const PolygonsIdx & polys,
float precision 
)
+
+ +

Triangulates a set of ε-valid polygons. If the input is not ε-valid, the triangulation may overlap, but will always return a manifold result that matches the input edge directions.

+
Parameters
+ + + +
polysThe set of polygons, wound CCW and representing multiple polygons and/or holes. These have 2D-projected positions as well as references back to the original vertices.
precisionThe value of ε, bounding the uncertainty of the input.
+
+
+
Returns
std::vector<glm::ivec3> The triangles, referencing the original vertex indicies.

Detailed Description

+

Examples of usage and interesting designs.

+

These are mostly 3D-printable designs I've invented over the years, translated from their original OpenSCAD to C++ to demonstrate the usage of this library. You can find the originals here: http://www.thingiverse.com/emmett These also each have tests you can find in test/samples_test.cpp, which have nice parameter choices for making some of the specific designs I print. While the source code is under the Apache License above, I license all of my designs (the output of those tests if you uncomment the export lines) under CC-BY-SA: https://creativecommons.org/licenses/by-sa/2.0/, which means you're welcome to print and sell them, so long as you attribute the design to Emmett Lalish and share any derivative works under the same license.

Function Documentation

+ +

◆ TorusKnot()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Manifold TorusKnot (int p,
int q,
float majorRadius,
float minorRadius,
float threadRadius,
int circularSegments,
int linearSegments 
)
+
+

Creates a classic torus knot, defined as a string wrapping periodically around the surface of an imaginary donut. If p and q have a common factor then you will get multiple separate, interwoven knots. This is an example of using the Manifold.Warp() method, thus avoiding any handling of triangles.

+
Parameters
+ + + + + + + + +
pThe number of times the thread passes through the donut hole.
qThe number of times the thread circles the donut.
majorRadiusRadius of the interior of the imaginary donut.
minorRadiusRadius of the small cross-section of the imaginary donut.
threadRadiusRadius of the small cross-section of the actual object.
circularSegmentsNumber of linear segments making up the threadRadius circle. Default is Quality.GetCircularSegments().
linearSegmentsNumber of segments along the length of the knot. Default makes roughly square facets.
+
+
+ +
+
+ +

◆ StretchyBracelet()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Manifold StretchyBracelet (float radius,
float height,
float width,
float thickness,
int nDecor,
int nCut,
int nDivision 
)
+
+

My Stretchy Bracelet: this is one of my most popular designs, largely because it's quick and easy to 3D print. The defaults are picked to work well; change the radius to fit your wrist. Changing the other values too much may break the design.

+
Parameters
+ + + + + + + + +
radiusThe overall size; the radius left for your wrist is roughly radius - height.
heightThickness of the bracelet around your wrist.
widthThe length along your arm (the height of the print).
thicknessThe width of the material, which should be equal to your printer's nozzle diameter.
nDecorThe number of twisty shapes around the outside.
nCutThe number of cuts that enable stretching.
nDivisionthe number of divisions along the width.
+
+
+ +
+
+ +

◆ MengerSponge()

+ +
+
+ + + + + + + + +
Manifold MengerSponge (int n)
+
+

The classic cubic fractal.

+
Parameters
+ + +
nFractal depth. Warning: scales exponentially, n = 4 has almost 400,000 triangles!
+
+
+ +
+
+ +

◆ RoundedFrame()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
Manifold RoundedFrame (float edgeLength,
float radius,
int circularSegments 
)
+
+

A cubic frame with cylinders for edges and spheres at the corners. Demonstrates how at 90-degree intersections, the sphere and cylinder facets match up perfectly.

+
Parameters
+ + + + +
edgeLengthDistance between the corners.
radiusRadius of the frame members.
circularSegmentsNumber of segments in the cylinders and spheres. Defaults to Quality.GetCircularSegments().
+
+
+ +
+
+ +

◆ TetPuzzle()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
Manifold TetPuzzle (float edgeLength,
float gap,
int nDivisions 
)
+
+

A tetrahedron cut into two identical halves that can screw together as a puzzle. This only outputs one of the halves. This demonstrates how redundant points along a polygon can be used to make twisted extrusions smoother.

+
Parameters
+ + + + +
edgeLengthLength of each edge of the overall tetrahedron.
gapSpacing between the two halves to allow sliding.
nDivisionsNumber of divisions (both ways) in the screw surface.
+
+
+ +
+
+ +

◆ Scallop()

+ +
+
+ + + + + + + +
Manifold Scallop ()
+
+

A smoothed manifold demonstrating selective edge sharpening with Manifold.Smooth(). Use Manifold.Refine() before export to see the curvature.

+ +
+
+ +

◆ GyroidModule()

+ +
+
+ + + + + + + + + + + + + + + + + + +
Manifold GyroidModule (float size,
int n 
)
+
+

Creates a rhombic dodecahedral module of a gyroid manifold, which can be assembled together to tile space continuously. This one is designed to be 3D-printable, as it is oriented with minimal overhangs. This sample demonstrates the use of a Signed Distance Function (SDF) to create smooth, complex manifolds.

Python Bindings

+

+Autogenerated Doc-Strings

+

Doc-strings for the python API wrapper are generated by gen_docs.py The script is run automatically during the build to keep python doc strings fully up-to-date with c++ sources.

+

It scrapes documentation comments and c++ function signatures from the manifold c++ sources, in order to generate a c++ header file exposing the comments as string variables named by function names. This allows python bindings to re-use the c++ comments directly.

+

Some snake-casing of params is applied for python use case.

+
+

When modifying the Manifold C++ sources, you may need to update gen_docs.py. For example, top-level free functions are white-listed, so if you add a new one, you will need to add it in gen_docs.py.

+

Similarly, the list of source files to parse is also white listed, so if you define functions in new files that need python wrappers, you will also need to up gen_docs.py.

+

To verify that python docs are correct after changes, you can run the following commends from the manifold repo root:

pip install .
+
python -c 'import manifold3d; help(manifold3d)'
+

Alternateively you could generate stubs with roughly the same info

pip install nanobind-stubgen
+
pip install .
+
nanobind-stubgen manifold3d
+

It will emit some warnings and write a file manifold3d.pyi which will show all the function signatures and docstrings.

  1. Go through Github issues to verify bugs have been fixed and closed.
    2. +
+

Verify ManifoldCAD.org - check a few examples, run them, download a GLB and a 3MF.

    +
  1. Verify our three.js example is functional.
    2. +
+
    +
  1. Verify our model-viewer example is functional - select Union and Intersection.
    2. +
+
    +
  1. Verify make-manifold is functional. Try dropping DragonAttenuation.glb in and verify you can select "View Manifold GLB" and that the dragon is still present while the backdrop is removed. Download the GLB.
    2. +
+
    +
  1. Make a new branch called the version, e.g. v2.3.0.

  1. Use VSCode to search and replace the old version with the new - so far in test-cmake.sh, flake.nix, pyproject.toml, and package.json.
    2. +
+
    +
  1. Also update CMakeLists.txt version by searching for "set(MANIFOLD_VERSION_".
    2. +
+
    +
  1. Commit, push, open a PR, verify tests pass, merge.
    2. +
+
    +
  1. On Github, draft a new release, make a new tag with the version number, add release notes, and publish.
    2. +
+
    +
  1. Check the Actions and verify that both PyPI and npm publishing actions ran successfully.
    2. +
+
    +
  1. Verify the npm package looks good - unpacked size should be close to 1MB.
    2. +
+
    +
  1. Verify PyPI package looks good - a bunch of built distributions ranging from ~600kB to ~1.1MB.

Detailed Description

+

The notation in these files is abbreviated due to the complexity of the functions involved. The key is that the input manifolds are P and Q, while the output is R, and these letters in both upper and lower case refer to these objects. Operations are based on dimensionality: vert: 0, edge: 1, face: 2, solid: 3. X denotes a winding-number type quantity from the source paper of this algorithm, while S is closely related but includes only the subset of X values which "shadow" (are on the correct side of).

+

Nearly everything here are sparse arrays, where for instance each pair in p2q1 refers to a face index of P interacting with a halfedge index of Q. Adjacent arrays like x21 refer to the values of X corresponding to each sparse index pair.

+

Note many functions are designed to work symmetrically, for instance for both p2q1 and p1q2. Inside of these functions P and Q are marked as though the function is forwards, but it may include a Boolean "reverse" that indicates P and Q have been swapped.

float Scale () const
+ 		+inline
+
+

Returns the absolute-largest coordinate value of any contained point.

+ +
+
+ +

◆ Contains() [1/2]

+ +
+
+ + + + + +
+ + + + + + + + +
bool Contains (const glm::vec3 & p) const

◆ Impl() [1/2]

+ +
+
+ + + + + + + + + + + + + + + + + + +
Impl (Shape shape,
const glm::mat4x3 m = glm::mat4x3(1) 
)
+
+

Create either a unit tetrahedron, cube or octahedron. The cube is in the first octant, while the others are symmetric about the origin.

+ +
+
+ +

◆ Impl() [2/2]

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Impl (const Mesh & mesh,
const MeshRelationD & relation,
const std::vector< float > & propertyTolerance = {},
bool hasFaceIDs = false 
)
+
+

Create a manifold from an input triangle Mesh. Will return an empty Manifold and set an Error Status if the Mesh is not manifold or otherwise invalid. TODO: update halfedgeTangent during SimplifyTopology.

+ +
+
+

Member Function Documentation

+ +

◆ CreateHalfedges()

+ +
+
+ + + + + + + + +
void CreateHalfedges (const Vec< glm::ivec3 > & triVerts)
+
+

Create the halfedge_ data structure from an input triVerts array like Mesh.

+ +
+
+ +

◆ CalculateNormals()

+ +
+
+ + + + + + + +
void CalculateNormals ()
+
+

If face normals are already present, this function uses them to compute vertex normals (angle-weighted pseudo-normals); otherwise it also computes the face normals. Face normals are only calculated when needed because nearly degenerate faces will accrue rounding error, while the Boolean can retain their original normal, which is more accurate and can help with merging coplanar faces.

+

If the face normals have been invalidated by an operation like Warp(), ensure you do faceNormal_.resize(0) before calling this function to force recalculation.

+ +
+
+ +

◆ IncrementMeshIDs()

+ +
+
+ + + + + + + +
void IncrementMeshIDs ()
+
+

Remaps all the contained meshIDs to new unique values to represent new instances of these meshes.

+ +
+
+ +

◆ Update()

+ +
+
+ + + + + + + +
void Update ()
+
+

Does a full recalculation of the face bounding boxes, including updating the collider, but does not resort the faces.

+ +
+
+ +

◆ EdgeCollisions()

+ +
+
+ + + + + + + + + + + + + + + + + + +
SparseIndices EdgeCollisions (const Impl & Q,
bool inverted = false 
) const
+
+

Returns a sparse array of the bounding box overlaps between the edges of the input manifold, Q and the faces of this manifold. Returned indices only point to forward halfedges.

+ +
+
+ +

◆ VertexCollisionsZ()

+ +
+
+ + + + + + + + + + + + + + + + + + +
SparseIndices VertexCollisionsZ (VecView< const glm::vec3 > vertsIn,
bool inverted = false 
) const
+
+

Returns a sparse array of the input vertices that project inside the XY bounding boxes of the faces of this manifold.

+ +
+
+ +

◆ CalculateBBox()

+ +
+
+ + + + + + + +
void CalculateBBox ()
+
+

Calculates the bounding box of the entire manifold, which is stored internally to short-cut Boolean operations and to serve as the precision range for Morton code calculation. Ignores NaNs.

+ +
+
+ +

◆ IsFinite()

+ +
+
+ + + + + + + +
bool IsFinite () const
+
+

Determines if all verts are finite. Checking just the bounding box dimensions is insufficient as it ignores NaNs.

+ +
+
+ +

◆ IsIndexInBounds()

+ +
+
+ + + + + + + + +
bool IsIndexInBounds (VecView< const glm::ivec3 > triVerts) const
+
+

Checks that the input triVerts array has all indices inside bounds of the vertPos_ array.

+ +
+
+ +

◆ SetPrecision()

+ +
+
+ + + + + + + + +
void SetPrecision (float minPrecision = -1)
+
+

Sets the precision based on the bounding box, and limits its minimum value by the optional input.

+ +
+
+ +

◆ IsManifold()

+ +
+
+ + + + + + + +
bool IsManifold () const
+
+

Returns true if this manifold is in fact an oriented even manifold and all of the data structures are consistent.

+ +
+
+ +

◆ Is2Manifold()

+ +
+
+ + + + + + + +
bool Is2Manifold () const
+
+

Returns true if this manifold is in fact an oriented 2-manifold and all of the data structures are consistent.

+ +
+
+ +

◆ MatchesTriNormals()

+ +
+
+ + + + + + + +
bool MatchesTriNormals () const
+
+

Returns true if all triangles are CCW relative to their triNormals_.

+ +
+
+ +

◆ NumDegenerateTris()

+ +
+
+ + + + + + + +
int NumDegenerateTris () const
+
+

Returns the number of triangles that are colinear within precision_.

+ +
+
+ +

◆ Finish()

+ +
+
+ + + + + + + +
void Finish ()
+
+

Once halfedge_ has been filled in, this function can be called to create the rest of the internal data structures. This function also removes the verts and halfedges flagged for removal (NaN verts and -1 halfedges).

+ +
+
+ +

◆ SortVerts()

+ +
+
+ + + + + + + +
void SortVerts ()
+
+

Sorts the vertices according to their Morton code.

+ +
+
+ +

◆ ReindexVerts()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void ReindexVerts (const Vec< int > & vertNew2Old,
int oldNumVert 
)
+
+

Updates the halfedges to point to new vert indices based on a mapping, vertNew2Old. This may be a subset, so the total number of original verts is also given.

+ +
+
+ +

◆ CompactProps()

+ +
+
+ + + + + + + +
void CompactProps ()
+
+

Removes unreferenced property verts and reindexes triProperties.

+ +
+
+ +

◆ GetFaceBoxMorton()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void GetFaceBoxMorton (Vec< Box > & faceBox,
Vec< uint32_t > & faceMorton 
) const
+
+

Fills the faceBox and faceMorton input with the bounding boxes and Morton codes of the faces, respectively. The Morton code is based on the center of the bounding box.

+ +
+
+ +

◆ SortFaces()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void SortFaces (Vec< Box > & faceBox,
Vec< uint32_t > & faceMorton 
)
+
+

Sorts the faces of this manifold according to their input Morton code. The bounding box and Morton code arrays are also sorted accordingly.

+ +
+
+ +

◆ GatherFaces()

+ +
+
+ + + + + + + + +
void GatherFaces (const Vec< int > & faceNew2Old)
+
+

Creates the halfedge_ vector for this manifold by copying a set of faces from another manifold, given by oldHalfedge. Input faceNew2Old defines the old faces to gather into this.

+ +
+
+ +

◆ Face2Tri()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void Face2Tri (const Vec< int > & faceEdge,
const Vec< TriRef > & halfedgeRef 
)
+
+

Triangulates the faces. In this case, the halfedge_ vector is not yet a set of triangles as required by this data structure, but is instead a set of general faces with the input faceEdge vector having length of the number of faces + 1. The values are indicies into the halfedge_ vector for the first edge of each face, with the final value being the length of the halfedge_ vector itself. Upon return, halfedge_ has been lengthened and properly represents the mesh as a set of triangles as usual. In this process the faceNormal_ values are retained, repeated as necessary.

+ +
+
+ +

◆ Face2Polygons()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
PolygonsIdx Face2Polygons (VecView< Halfedge >::IterC start,
VecView< Halfedge >::IterC end,
glm::mat3x2 projection 
) const
+
+

Returns a set of 2D polygons formed by the input projection of the vertices of the list of Halfedges, which must be an even-manifold, meaning each vert must be referenced the same number of times as a startVert and endVert.

+ +
+
+ +

◆ SimplifyTopology()

+ +
+
+ + + + + + + +
void SimplifyTopology ()
+
+

Collapses degenerate triangles by removing edges shorter than precision_ and any edge that is preceeded by an edge that joins the same two face relations. It also performs edge swaps on the long edges of degenerate triangles, though there are some configurations of degenerates that cannot be removed this way.

+

Before collapsing edges, the mesh is checked for duplicate edges (more than one pair of triangles sharing the same edge), which are removed by duplicating one vert and adding two triangles. These degenerate triangles are likely to be collapsed again in the subsequent simplification.

+

Note when an edge collapse would result in something non-manifold, the vertices are duplicated in such a way as to remove handles or separate meshes, thus decreasing the Genus(). It only increases when meshes that have collapsed to just a pair of triangles are removed entirely.

+

Rather than actually removing the edges, this step merely marks them for removal, by setting vertPos to NaN and halfedge to {-1, -1, -1, -1}.

+ +
+
+ +

◆ SetNormals()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void SetNormals (int normalIdx,
float minSharpAngle 
)
+
+

Instead of calculating the internal shared normals like CalculateNormals does, this method fills in vertex properties, unshared across edges that are bent more than minSharpAngle.

+ +
+
+ +

◆ CreateTangents() [1/2]

+ +
+
+ + + + + + + + +
void CreateTangents (int normalIdx)
+
+

Calculates halfedgeTangent_, allowing the manifold to be refined and smoothed. The tangents form weighted cubic Beziers along each edge. This function creates circular arcs where possible (minimizing maximum curvature), constrained to the indicated property normals. Across edges that form discontinuities in the normals, the tangent vectors are zero-length, allowing the shape to form a sharp corner with minimal oscillation.

+ +
+
+ +

◆ CreateTangents() [2/2]

+ +
+
+ + + + + + + + +
void CreateTangents (std::vector< Smoothness > sharpenedEdges)
+
+

Calculates halfedgeTangent_, allowing the manifold to be refined and smoothed. The tangents form weighted cubic Beziers along each edge. This function creates circular arcs where possible (minimizing maximum curvature), constrained to the vertex normals. Where sharpenedEdges are specified, the tangents are shortened that intersect the sharpened edge, concentrating the curvature there, while the tangents of the sharp edges themselves are aligned for continuity.

+ +
+
+ +

◆ Subdivide()

+ +
+
+ + + + + + + + +
Vec< Barycentric > Subdivide (std::function< int(glm::vec3)> edgeDivisions)
+
+

Split each edge into n pieces as defined by calling the edgeDivisions function, and sub-triangulate each triangle accordingly. This function doesn't run Finish(), as that is expensive and it'll need to be run after the new vertices have moved, which is a likely scenario after refinement (smoothing).

Detailed Description

+

An alternative to Mesh for output suitable for pushing into graphics libraries directly. This may not be manifold since the verts are duplicated along property boundaries that do not match. The additional merge vectors store this missing information, allowing the manifold to be reconstructed.

+

Member Function Documentation

+ +

◆ Merge()

+ +
+
+ + + + + + + +
bool Merge ()
+
+

Updates the mergeFromVert and mergeToVert vectors in order to create a manifold solid. If the MeshGL is already manifold, no change will occur and the function will return false. Otherwise, this will merge verts along open edges within precision (the maximum of the MeshGL precision and the baseline bounding-box precision), keeping any from the existing merge vectors.

+

There is no guarantee the result will be manifold - this is a best-effort helper function designed primarily to aid in the case where a manifold multi-material MeshGL was produced, but its merge vectors were lost due to a round-trip through a file format. Constructing a Manifold from the result will report a Status if it is not manifold.

+ +
+
+

Member Data Documentation

+ +

◆ vertProperties

+ +
+
+ + + + +
std::vector<float> vertProperties
+
+

Flat, GL-style interleaved list of all vertex properties: propVal = vertProperties[vert * numProp + propIdx]. The first three properties are always the position x, y, z.

+ +
+
+ +

◆ triVerts

+ +
+
+ + + + +
std::vector<uint32_t> triVerts
+
+

The vertex indices of the three triangle corners in CCW (from the outside) order, for each triangle.

+ +
+
+ +

◆ mergeFromVert

+ +
+
+ + + + +
std::vector<uint32_t> mergeFromVert
+
+

Optional: A list of only the vertex indicies that need to be merged to reconstruct the manifold.

+ +
+
+ +

◆ mergeToVert

+ +
+
+ + + + +
std::vector<uint32_t> mergeToVert
+
+

Optional: The same length as mergeFromVert, and the corresponding value contains the vertex to merge with. It will have an identical position, but the other properties may differ.

+ +
+
+ +

◆ runIndex

+ +
+
+ + + + +
std::vector<uint32_t> runIndex
+
+

Optional: Indicates runs of triangles that correspond to a particular input mesh instance. The runs encompass all of triVerts and are sorted by runOriginalID. Run i begins at triVerts[runIndex[i]] and ends at triVerts[runIndex[i+1]]. All runIndex values are divisible by 3.

+ +
+
+ +

◆ runOriginalID

+ +
+
+ + + + +
std::vector<uint32_t> runOriginalID
+
+

Optional: The OriginalID of the mesh this triangle run came from. This ID is ideal for reapplying materials to the output mesh. Multiple runs may have the same ID, e.g. representing different copies of the same input mesh. If you create an input MeshGL that you want to be able to reference as one or more originals, be sure to set unique values from ReserveIDs().

+ +
+
+ +

◆ runTransform

+ +
+
+ + + + +
std::vector<float> runTransform
+
+

Optional: For each run, a 3x4 transform is stored representing how the corresponding original mesh was transformed to create this triangle run. This matrix is stored in column-major order and the length of the overall vector is 12 * runOriginalID.size().

+ +
+
+ +

◆ faceID

+ +
+
+ + + + +
std::vector<uint32_t> faceID
+
+

Optional: Length NumTri, contains an ID of the source face this triangle comes from. When auto-generated, this ID will be a triangle index into the original mesh. All neighboring coplanar triangles from that input mesh will refer to a single triangle of that group as the faceID. When supplying faceIDs, ensure that triangles with the same ID are in fact coplanar and have consistent properties (within some tolerance) or the output will be surprising.

+ +
+
+ +

◆ halfedgeTangent

+ +
+
+ + + + +
std::vector<float> halfedgeTangent
+
+

Optional: The X-Y-Z-W weighted tangent vectors for smooth Refine(). If non-empty, must be exactly four times as long as Mesh.triVerts. Indexed as 4 * (3 * tri + i) + j, i < 3, j < 4, representing the tangent value Mesh.triVerts[tri][i] along the CCW edge. If empty, mesh is faceted.

+ +
+
+ +

◆ precision

+ +
+
+ + + + +
float precision = 0
+
+

The absolute precision of the vertex positions, based on accrued rounding errors. When creating a Manifold, the precision used will be the maximum of this and a baseline precision from the size of the bounding box. Any edge shorter than precision may be collapsed.

◆ meshID

+ +
+
+ + + + +
int meshID
+
+

The unique ID of the mesh instance of this triangle. If .meshID and .tri match for two triangles, then they are coplanar and came from the same face.

+ +
+
+ +

◆ originalID

+ +
+
+ + + + +
int originalID
+
+

The OriginalID of the mesh this triangle came from. This ID is ideal for reapplying properties like UV coordinates to the output mesh.

+ +
+
+ +

◆ tri

+ +
+
+ + + + +
int tri
+
+

The triangle index of the original triangle this was part of: Mesh.triVerts[tri].
