It helps me for one. I have a (much more difficult to answer) question: how
about Fourier analysis of a rgb coded color? Will it be easier if
light_sources are (optionally) specified as wavelengths? What if there is a
filter_map and reflecton_map to specify the absorbtion and reflection
spectra of a bofy? Won't these give more realistic light dispersion than the
current dispersion patch gives? I once wanted to develop (only the math
stuff of) a dispersion patch but gave up at the above questions. I came up
with the same sampling algorithm used in the dispersion patch (back then I
was thinking of more user control to it but it turned  out it looks fine as
is)
