Getting Started

Build and Run

Install node.js

Install all dependencies, as specified in package.json:

npm install

Use npm run build to create ./build/potree.

Use the npm start command to

  • create ./build/potree
  • watch for changes to the source code and automatically create a new build on change
  • start a web server at localhost:1234.

Go to http://localhost:1234/examples/ to test the examples.


Download PotreeConverter and run it like this:

./PotreeConverter.exe C:/pointclouds/data.las -o C:/pointclouds/data_converted

Copy the converted directory into <potreeDirectory>/pointclouds/data_converted. Then, duplicate and rename one of the examples and modify the path in the html file to your own point cloud.

  • The multi-res-octree algorithms used by this viewer were developed at the Vienna University of Technology by Michael Wimmer and Claus Scheiblauer as part of the Scanopy Project.
  • Three.js, the WebGL 3D rendering library on which potree is built.
  • point cloud viewer. LAS and LAZ support have been taken from the laslaz.js implementation of Thanks to Uday Verma and Howard Butler for this!
  • Harvest4D Potree currently runs as Master Thesis under the Harvest4D Project
  • Christian Boucheny (EDL developer) and Daniel Girardeau-Montaut (CloudCompare). The EDL shader was adapted from the CloudCompare source code!
  • Martin Isenburg, Georepublic, Veesus, Sigeom Sa, SITN, LBI ArchPro, Pix4D as well as all the contributers to potree and PotreeConverter and many more for their support.
