Rendering BRDF measured data(custom)withRadiance

one is that for indirect calculation it's all based on the r g b
coefficients.

the second is that 'specular reflection' will work just with sources and
not the environment.

so for instance if you are rendering a motorway with a wet asphalt it
will how the reflection of the luminaire but not the reflection of the
other objects.

what are you using BRDF for?

yes you can but with some limitations.

you need to write a cal file to describe how the data is collected.

plasdata/transdata are a good start.

Dear All,

Some one can tell me if it possible to render BRDF data measurement with
Radiance?

Thanks in advance.

Best Regards,

Alessandro.
