has anyone done any speed tests on backface removal using surface comands ?
ie. if you are rendering a sphere, half of its polygons are backfacing at any given time. You can use triangle normals and the direction your camera is facing to figure out if you can see the triangles. I noticed in the docs it suggested to use the surface commands for dynamic LOD, so wouldn't it work good to do backface removal at the same time ... ? haven't tried it yet , just a thought.
