The way Radiance deals with translucent materials is interesting but requires some knowledge about material parameters, especially the roughness parameter. It is possible to measure glass sheets and then fit the parameters to the data but I guess somebody has already made this.
Do you know and can you recommend any material libraries for transparent and translucent materials? How could they be obtained (links, contact information etc.)?
