[Radiance-general] About Radinace - Lens material

[Greg Ward]

Dear Neha,

Radiance uses ray-tracing to perform lighting calculations in  
buildings.  It is not configured for optical ray-tracing.  For such a  
purpose, you are better off with any of the number of commercial  
packages available (TracePro, Optics Lab, ORA LightTools, etc.)   
While it is *possible* to use Radiance for optical design, it is not  
geared for it, and you won't find many people who have applied it to  
this task.  I am just starting to work with it myself, but even the  
accurate definition of a lens given the lack of bicubic patches is  
problematic.

Best,
-Greg
