Just Blur and Add Noise

August 29, 2007 at 2:07 pm (Game techniques, Presentations)

All of the hoopla regarding the game LittleBigPlanet has reminded me of the excellent talk that Alex Evans, co-founder of game creator Media Molecule, gave last year at the Advanced Real-time Rendering for 3D Games course at SIGGRAPH 2006. There are good presentation slides in PDF form at the ATI Developer site: here. If you look at the slide pictures you can see early renders of LittleBigPlanet characters, with unfortunate spheres places on their heads so as not to spoil the game (this was about nine months before the game was announced).

Anyway, he discusses a few techniques that he tried in achieving global illumination-like effects in a “small world” type of environment, all of which were implemented on a Radeon mobility 9800; nothing is too high tech.
