Instant Radiosity

I’ve been following the state of real-time Instant Radiosity for a while now. I see it as one of the best options for a gpu-friendly transition to more complex global illumination techniques like photon mapping. Unfortunately I never got around to implement it myself in order to verify it’s feasibility. Today I stumbled upon one of the best examples so far:

Flavien Brebion, aka Ysaneya, is the guy behind Infinity. He is also the guy behind the bold attempt at Instant Radiosity in the shots above. In his journal he talks about the technique and provides some statistics on its effectiveness when combined with deferred lighting. Follow this link to read all about it.
