App

osgbTo3mx

Convert osgb lod tree to Bentley ContextCapture 3mx tree.

pointcloudToLod

Convert point cloud in ply/las/laz/xyz format to osgb/3mx lod tree, so that the point cloud could be loaded instantly.
This program could handle extremely large point cloud as ply/las/laz/xyz file is streaming to the convertor.

NOTE: Official 3mx does NOT support pointcloud, this project extended 3mx to make it happen. Please read the doc for details.

meshToLod (WIP)

Convert mesh in obj format to osgb/3mx lod tree, so that the mesh could be loaded instantly.
This program only support obj format mesh with group info, each group will be a tile in the lod tree.
