Heya

I was thinking.... yup, i was! Would there be any advantage of doing an ambient occlusion baking mel script that used the openGL og Fx from a graphics card to sample occlusion?
Maybe it could be written as a cG shader actually? :)

I would be really interested in a CG ambient Occlusion shader especially if you could bake it. I haven't had too much time to look into it but I have an FX1000 card and I saw a demo of some ambient occlusion with it at siggraph and it looked pretty nice.

The advange would be speed of course.. it shoudlbe really fast to do.

do you happen to know if the papers on those demos are available anywhere? I just got my fx5900 ultra today, and i'll install the Cg ide tomorrow and see if i can figure it out :)
