Create multi res point cloud to use with potree

Potree Converter

Master: Develop:

Builds a potree octree from las, laz, binary ply, xyz or ptx files.

Downloads

• Source Code and windows 64bit releases

Dependencies

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

Build

linux / gcc 4.9

lastools (from fork with cmake)

cd ~/dev/workspaces/lastools
git clone https://github.com/m-schuetz/LAStools.git master
cd master/LASzip
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

PotreeConverter

cd ~/dev/workspaces/PotreeConverter
git clone https://github.com/potree/PotreeConverter.git master
cd master
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DLASZIP_INCLUDE_DIRS=~/dev/workspaces/lastools/master/LASzip/dll -DLASZIP_LIBRARY=~/dev/workspaces/lastools/master/LASzip/build/src/liblaszip.so ..
make

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

OS X

Same as the linux instructions above, except:

1. Give cmake absolute paths to the LASzip tools you just built. (Otherwise make might not be able to find them)
2. LASZip library will be called liblaszip.dylib, not liblaszip.so

...

cmake -DCMAKE_BUILD_TYPE=Release -DLASZIP_INCLUDE_DIRS=[ABSOLUTE_PATH_TO_LASTOOLS]/master/LASzip/dll -DLASZIP_LIBRARY=[ABSOLUTE_PATH_TO_LASTOOLS]/master/LASzip/build/src/liblaszip.dylib ..
make

Windows / Microsoft Visual Studio 2017:

lastools

cd D:/dev/workspaces/lastools/
git clone https://github.com/m-schuetz/LAStools.git master
cd master/LASzip
mkdir build
cd build
cmake -G "Visual Studio 15 2017 Win64" ../

# make sure you've got these environment variables set with your directory structure
set LASZIP_INCLUDE_DIRS=D:\dev\workspaces\lastools\master\LASzip\dll
set LASZIP_LIBRARY=D:\dev\workspaces\lastools\master\LASzip\build\src\Release\laszip.lib

# checkout PotreeConverter
cd D:/dev/workspaces/PotreeConverter
git clone https://github.com/potree/PotreeConverter.git master
cd master
mkdir build
cd build

# VS2017 64bit project
cmake -G "Visual Studio 15 2017 Win64" -DLASZIP_INCLUDE_DIRS=%LASZIP_INCLUDE_DIRS% -DLASZIP_LIBRARY=%LASZIP_LIBRARY%  ..\

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

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:

-h [ --help ]                           prints usage
-p [ --generate-page ] arg              Generates a ready to use web page with the given name.
-o [ --outdir ] arg                     output directory
-s [ --spacing ] arg                    Distance between points at root level. Distance halves each level.
-d [ --spacing-by-diagonal-fraction ] arg
                                        Maximum number of points on the diagonal in the first level (sets spacing). spacing = diagonal / value
-l [ --levels ] arg                     Number of levels that will be generated. 0: only root, 1: root and its children, ...
-f [ --input-format ] arg               Input format. xyz: cartesian coordinates as floats, rgb: colors as numbers, i: intensity as number
--output-format arg                     Output format can be BINARY, LAS or LAZ. Default is BINARY
-a [ --output-attributes ] arg          can be any combination of RGB, INTENSITY, CLASSIFICATION and NORMAL. Default is RGB.
--scale arg                             Scale of the X, Y, Z coordinate in LAS and LAZ files.
--aabb arg                              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 arg                            Source file. Can be LAS, LAZ, PTX or PLY

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
