I had done that 4 years ago with the (original?) sig2pix external that I wrote. It was fast. It was not very general though ...

the sig2pix hasn't changed much since (at least i don't think that performance has decreased) i haven't done any profiling, but i think a lot of CPU-power is wasted while casting from float to int and back again, and when getting the luminance of the image to map to vertices. performance isn't *that* bad, bit i thought it could be better.

i don't think that conversion to pixes and then to vertices is optimal.

Just found it amusing ... back to lurker state.
