[Radiance-general] glass diffuser?

There are lots of such products. What you describe would lead to frosted 
glass, which can be describes in Radiance using the trans modifier. In 
most cases, one would use clear glass, acrylic, polycarbonat with a 
structure to scatter or redirect light. This has the advantage that 
unlike diffuse materials, which also reflect back light to the outside, 
with clear geometry you can still make sure that the light enters your room.
