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?
