Any suggestions on a good, efficient algorithm for testing for the visibility of an object? Thanks --- Matt Benic "Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning."

1. bounding sphere round each object.
2. hierarchy of bounding spheres to group objects.
3. test spheres hierarchically against a cone representing the frustum.

That should be enough to cull away the vast majority of what isn''t visible.

- Portal
- PVS
- Quadtree/Octree/BSPTree
- Occlusion Culling
