envmap.pdf | An Efficient Representation for Irradiance Environment Maps Spherical Harmonics and applications in real time graphics I am using Spherical Harmonics to turn reflective(mirror like) cube map to diffuse light cube map. From what I…

I'm looking for a compact representation of radiance over the hemisphere that is also performant to evaluate in realtime (in a pixel shader). The purpose of it is to compress surface lightfields so that they are also very performant to render in…
