Hi,

In Povray, the optical properties of each surface can be set by ambient, diffuse
and specular. This is very flexible but only single value is allowed over
color-channels. As a matter of fact, the optical properties of object often
differs over wavelength or colors. I am wondering what's the assumption in
Povary to deal with this. It will be great if you could recommend a reference to
describe the raytracing theory used in Povray. Thanks a lot in advance.

Best regards
Shouyang
