LOPOCS is a point cloud server written in Python, allowing to load Point Cloud from Postgis thanks to the pgpointcloud extension.
Point Cloud are loaded in database thanks to PDAL and patches are compressed in LAZ. To stream hundreds of millions of points with LOD in an effective way, points are ordered with the Midoc algorithm and a revert Morton code is used when too many patches are involved!
The Potree viewer is currently able to display points coming from LOPoCS through a simple HTTP protocol.
Some development has been in made in various projects:
- PDAL : a new filter implementing the Midoc algorithm
- pgpointcloud : LAZ compression with laz-perf (several new functions)
- Potree : a new loader
Everything is on github : https://github.com/LI3DS/
LI³DS is an OpenSource project by Oslandia and IGN for 3D scanning and data management. LOPoCS is the result of a great collaboration, in particular with Rémi Cura and Mathieu Brédif.
And plenty of new people in perspective!
