I was amazed by this real Time GI stuff too, but poorly this is very old footage :roll:

Since a very long time this Fantasy Lab Guys don't show anything new :(

I got a interesting Technical Video of Real Time GI on GPU for DX10, I'm just uploading to rapidshare...

**EDIT**
HEREis the download link

I believe they're using the technique described in GPU Gems II. Pixar recently implemented this in prman for production-quality rendering, and it is very, very fast.

Not accurate at all tho :)

That second video is from a paper at last year's siggraph. It's not really GI, more a clever way of doing a dynamic, spherical-harmonics-based ibl solution. So it doesn't really allow for any brdf other than lambertian.

It's real-time faked GI :)

You can get a neat looking system though, using spherical harmonics. (Which are pre-computed by nature)
