[Radiance-general] Spectrophotometer Data to Radiance Surface Descriptions

[R Fritz]

If I have diffuse and specular XYZ surface data from a 
spectrophotometer—six numbers—, how do I convert that into Radiance 
material descriptions? Can I calculate the "specularity" for types 
plastic and metal from that data? Or do I need to use a function or 
data-based material type?
