Irradiance volumes
November 13th, 2008
About 5 years ago, creating spherical harmonic values for irradiance volumes was painful. There were no tools, just a hodge-podge of code strung together with scripts.
Turtle from Illuminate Labs now makes it trivial.
You can bake everything from Ambient Occlusion to Radiosity Normal Maps to spherical harmonic coefficients with ease and full control (with Lua-based shaders). Amazing what art tools can do to increase productivity and quality.
BTW Turtle / Beast was used in Mirror’s Edge which looks like it was globally illluminated perfectly (see the cool sky mix with the warm sunlight).
