PC, current gen. It's for a real time pseuso global illumination
attempt. I currently need a 10 second preprocess step to compute how
vertexes "see" each other on the Sponza Atrium or the Sibenik Cathedrals
from http://hdri.cgtechniques.com/~sponza/
Which means I can have dynamic lights, but my models are to be static.
I'd like to see how much I could speed that up, even if dynamic meshes
seem quite far away.
