Research hidden surface removal and create proof of concept demo
Reported by Andor Salga | June 8th, 2010 @ 07:56 PM | in 0.7
We can spatially partition the point cloud and then do octree-frustum culling, but we'll need to implement other hidden surface removal techniques as well to get decent frame rates. We don't have access to the ARB_occlusion_query extension, but we may not need it if all the objects are enclosed anyway.
- Octree BB tests?
- Depth sorting?
- Ray tracing?
- Scan lines?
