T_Rhino_Geometry_MeshFace

MeshFace Structure

Represents the values of the four indices of a mesh face quad. If the third and fourth values are the same, this face represents a triangle.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: Rhino 6.0

Syntax

C#

[SerializableAttribute]
public struct MeshFace : IEquatable<MeshFace>, 
	IComparable<MeshFace>, IComparable

VB

<SerializableAttribute>
Public Structure MeshFace
	Implements IEquatable(Of MeshFace), IComparable(Of MeshFace), 
	IComparable

The MeshFace type exposes the following members.

Constructors

 

	Name	Description
	MeshFace(Int32, Int32, Int32)	Constructs a new triangular Mesh face.
	MeshFace(Int32, Int32, Int32, Int32)	Constructs a new quadrangular Mesh face.

Properties

 

	Name	Description
	A	Gets or sets the first corner index of the mesh face.
	B	Gets or sets the second corner index of the mesh face.
	C	Gets or sets the third corner index of the mesh face.
	D	Gets or sets the fourth corner index of the mesh face. If D equals C, the mesh face is considered to be a triangle rather than a quad.
	IsQuad	Gets a value indicating whether or not this mesh face is a quad. A mesh face is considered to be a triangle when C does not equal D, thus it is possible for an Invalid mesh face to also be a quad.
	IsTriangle	Gets a value indicating whether or not this mesh face is a triangle. A mesh face is considered to be a triangle when C equals D, thus it is possible for an Invalid mesh face to also be a triangle.
	Item	Gets or sets the vertex index associated with an entry in this face.
	Unset	Gets an Unset MeshFace. Unset faces have Int32.MinValue for all corner indices.

Methods

 

	Name	Description
	CompareTo	Compares this MeshFace with another MeshFace and returns a value of 1, 0, or -1, referring to dictionary order. Index evaluation priority is first A, then B, then C, then D.
	Equals(Object)	Indicates whether this instance and a specified object are equal. (Inherited from ValueType.)
	Equals(Object)	Returns a value indicating whether the other object obj has precisely the same value as the current one. (Overrides ValueType.Equals(Object).)
	Equals(MeshFace)	Returns a value indicating whether the other mesh face has precisely the same value as the current one.
	Flip	Reverses the orientation of the face by swapping corners. The first corner is always maintained.
	GetHashCode()	Returns the hash code for this instance. (Inherited from ValueType.)
	GetHashCode()	Returns a runtime-stable hashcode for the current mesh face. You are not allowed to rely on persistance of this hashcode in serialization, but for each version of RhinoCommon, this hashcode will be the same for each mesh face. (Overrides ValueType.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsValid()	Gets a value indicating whether or not this mesh face is considered to be valid. Note that even valid mesh faces could potentially be invalid in the context of a specific Mesh, if one or more of the corner indices exceeds the number of vertices on the mesh. If you want to perform a complete validity check, use IsValid(int) instead.
	IsValid(Int32)	Gets a value indicating whether or not this mesh face is considered to be valid. Unlike the simple IsValid function, this function takes upper bound indices into account.
	IsValid(Point3d[])	Gets a value indicating whether or not this mesh face is considered to be valid. Unlike the simple IsValid function, this function takes actual point locations into account.
	Repair	Attempts to repair this mesh face by taking both face indexes and actual vertex locations into account.
	Set(Int32, Int32, Int32)	Sets all the corners for this face as a triangle.
	Set(Int32, Int32, Int32, Int32)	Sets all the corners for this face as a quad.
	ToString()	Returns the fully qualified type name of this instance. (Inherited from ValueType.)
	ToString()	Returns a string representation for this MeshFace. This is to provide a meaningful visualization of this structure and is subject to change in newer releases. (Overrides ValueType.ToString().)

Operators

 

	Name	Description
	Equality	Determines whether two MeshFace structures have equal values.
	Inequality	Determines whether two MeshFace structures have different values.
