Basic Spectral render is 10 lines, it simplest thing that still not in
trunk. One additional sampling dimension, and apply black body curve
sampled by that to actual color before store to pixel buffer.
Some BSDF need to respect it, as glass, and current wavelenght must be
exposed to shaders, it take 10 more lines of code. I have done it long
The problem is it hardly to be usable (as volumetrics things btw), only
few extreme scenes with diamonds on floor. And in turn, most cool part
is caustic, it take looong time to converge even with MLT.
