Potree - Rendering Point Clouds in Web Browsers Markus Schütz, www.potree.org/
Potree
Potree ● Web Viewer for large point clouds ● Uses WebGL / three.js ● No Plugins required ● Works on Chrome, Firefox, Safari on desktop PCs and mobile devices (iPad4, smartphones, …) ● Also IE11 but not as fast and some bugs ● Entirely client side application. Server only hosts files but does not execute code. ● Don't load full point cloud data → load visible regions up to a certain level of detail
Potree 1. level 5. level 2. level
Workflow 1.Convert point cloud with PotreeConverter 2.Modify examples to use converted data 3.Upload to WebServer See Getting Started: https://github.com/potree/potree/blob/master/docs/getting_started.md
Features ● Different Materials (RGB, Intensity, Classification, …) ● 4 Point Rendering Modes (Squares, Circles, Interpolation, Splats) ● PotreeConverter creates BINARY, LAZ(compressed) or LAS hierarchy. ● Based on three.js so everything three.js can do, too. ● Distance, Area and Height Profile Measurements ● Fixed, Attenuated and Adaptive Point Sizes ● Georeferencing
Materials Height RGB Intensity Classification
Point Rendering Quality Squares Circles Interpolation Splats
Measurements
Georeferencing ● Minimap with real world position ● Project Map (Bing, OSM, ...) on point cloud (Work In Progress) Original Original Bing OpenStreetMap
Potree ● Based on Scanopy, a desktop point cloud viewer from the Vienna University of Technology cg department http://cg.tuwien.ac.at/research/projects/TERAPOINTS/ ● Free and Open Source, available on github ● Now continued as master thesis under the Harvest4D project: http://harvest4d.org
