Since the teaser at the end of the CryTek presentation “A Bit More Deferred”, I’ve been wondering what those guys are up to with their real-time diffuse GI solution. It was presented at SIGGRAPH 09 in the “Advances in Real-Time Rendering”  course. Now the slides are online! Looks like they are rendering radiance from directly lit surfaces to a volume and propagating the light outward like in Alex Evan’s presentation from a few years before (though CryTek’s approach is a bit more physically based).  Pretty cool.
