Dependencies

• lastools(LASzip) or fork of lastools with cmake for LASzip

Build

linux / gcc 4.9 and OS X

PotreeConverter

make

# copy ./PotreeConverter/resources/page_template to your binary working directory.

Windows / Microsoft Visual Studio 2017:

lastools

cd LAStools/LASzip

PotreeConverter Usage

Converts las files to the potree file format. You can list multiple input files. If a directory is specified, all files inside the directory will be converted.

Options:

$ PotreeConverter -h                                      
  -i [ --source ]                        input files
  -h [ --help ]                          prints usage
  -p [ --generate-page ]                 Generates a ready to use web page with the given name.
  -o [ --outdir ]                        output directory
  -s [ --spacing ]                       Distance between points at root level. Distance halves each level.
  -d [ --spacing-by-diagonal-fraction ]  Maximum number of points on the diagonal in the first level (sets spacing). spacing = diagonal value
  -l [ --levels ]                        Number of levels that will be generated. 0: only root, 1: root and its children, ...
  -f [ --input-format ]                  Input format. xyz: cartesian coordinates as floats, rgb: colors as numbers, i: intensity as number
  --color-range
  --intensity-range
  --output-format                        Output format can be BINARY, LAS or LAZ. Default is BINARY
  -a [ --output-attributes ]             can be any combination of RGB, INTENSITY and CLASSIFICATION. Default is RGB.
  --scale                                Scale of the X, Y, Z coordinate in LAS and LAZ files.
  --aabb                                 Bounding cube as "minX minY minZ maxX maxY maxZ". If not provided it is automatically computed
  --incremental                          Add new points to existing conversion
  --overwrite                            Replace existing conversion at target directory
  --source-listing-only                  Create a sources.json but no octree.
  --projection                           Specify projection in proj4 format.
  --list-of-files                        A text file containing a list of files to be converted.
  --source                               Source file. Can be LAS, LAZ, PTX or PLY
  --title                                Page title
  --description                          Description to be shown in the page.
  --edl-enabled                          Enable Eye-Dome-Lighting.
  --show-skybox
  --material                             RGB, ELEVATION, INTENSITY, INTENSITY_GRADIENT, RETURN_NUMBER, SOURCE, LEVEL_OF_DETAIL

Examples:

# convert data.las and generate web page.
./PotreeConverter.exe C:/data.las -o C:/potree_converted -p pageName

# generate compressed LAZ files instead of the default BIN format.
./PotreeConverter.exe C:/data.las -o C:/potree_converted --output-format LAZ

# convert all files inside the data directory
./PotreeConverter.exe C:/data -o C:/potree_converted

# first, convert with custom bounding box and then append new_data.las afterwards.
# points in new_data MUST fit into bounding box!
./PotreeConverter.exe C:/data -o C:/potree_converted -aabb "-0.748 -2.780 2.547 3.899 1.867 7.195"
./PotreeConverter.exe C:/new_data.las -o C:/potree_converted --incremental

# tell the converter that coordinates are in a UTM zone 10N projection. Also, create output in LAZ format
./PotreeConverter.exe C:/data -o C:/potree_converted -p pageName --projection "+proj=utm +zone=10 +ellps=GRS80 +datum=NAD83 +units=m +no_defs" --overwrite --output-format LAZ

# using a swiss projection. Use http://spatialreference.org/ to find projections in proj4 format
./PotreeConverter.exe C:/data -o C:/potree_converted -p pageName --projection "+proj=somerc +lat_0=46.95240555555556 +lon_0=7.439583333333333 +k_0=1 +x_0=600000 +y_0=200000 +ellps=bessel +towgs84=674.4,15.1,405.3,0,0,0,0 +units=m +no_defs" --overwrite
