[Algorithms] VIPM With T&L

[Sam K. <sa...@ip...>]

Hi all,

This is bound to have been covered a gazillion times before, but I'm having
trouble searching the archives:
I'm fairly new to VIPM, and have a couple of questions:

a) I've read that its possible to throw the vertices of a model at the 3d
card (So T&L is possible)
And just maintain the indexed lists into that vertex array using collapses
and merges.
Doesn't that mean you have to make the card (hardware) transform all of the
vertices in the highest resolution representation of the model each frame?
even though the current lod might only need say 100.. or am I missing
something?

b) Say you wanted 1000 spaceships on screen sharing a single VIPM model, how
does this work with (a)?
Does the card have to transform all the original (high lod) vertices 1000
times to screen space?

Is it that the hardware T&L only transforms vertices that are pointed to by
the supplied indexed lists? or what

Thanks,

sam
