Does anybody have a link to a whitepaper/presentation of the method used by Insomniac to implement radiosity normal mapping in the Resistance: Fall of Man game?
Radiosity normal mapping, as implemented in the Source engine, uses three lightmaps, calculcated along three perpendicular axis. In Resistance, they do away with a single texture which isn't really a lightmap, as it stores in the texels the direction of the light rays. What about light color? Do they use a second texture, which is just a matrix of RGB scalar values? Any info would be appreciated.
PS: Sometimes I feel I'm still living in the stone age of 3D computer graphics (and, on top of that, I haven't really coded anything since the days of the fixed functions cards)
