Usually, for Lidar data that is fully 3D, and not just a 2.5D heightfield, you'll want a full octree, not a quadtree. I'm assuming you're using LibLAS. An associate of mine has been doing work on LibLAS to extend it with queryable spatial indexing, and possibly frustum querying in the future. You should check into the recent work on LibLAS. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging. OpenGL. Scene Graphs. GIS. GPS. Training.
