[Radiance-general] POLYCARBONATE RADIANCE FILES

[Peter Apian-Bennewitz]

Hi Tim,

polycarbonate spectral transmittance or BSDF (distribution of scattered light) 
data or model of polycarbonate double-walled extruded sheets, like "Lexan 
Thermoclear" ?

For the latter, how accurate you want to model the typical glare "ring" ? Just 
its position (relatively simple cal file) or a complete model for a specific 
material ?

best
Peter
