RE: [Algorithms] View-Depend vs. View-Independent LOD

[Tom F. <to...@mu...>]

If you look at the amount of CPU work required for VIPM, it's tiny. And you
don't touch any vertex data, just indices. It certainly is useful for scenes
with lots of people - my characters go up to around 120ktris each. Draw
twenty of them at full rez, and you'll kill even the best chip. VIPM is
absoloutely required for this sort of stuff, and it's very fast.
