About BRDF about iron HOT 4 CLOSED

Usually, plastic and metal materials can be modelled by the same class of parametric BRDF, e.g., disney BRDF; and these are probably the most common materials in literature. Inverse rendering with general materials is still an open problem, I think.

It's the roughplastic BRDF in Mitsuba; see section 8.2.9 in this pdf: https://www.mitsuba-renderer.org/releases/current/documentation.pdf . However, one can also switch to the simplified Disney BRDF as in PhySG; it's on our development roadmap, but I haven't got time to implement it yet.

I see. In many other related papers, I notice that there are usually some prio assumption about the brdf function or brdf parameters according to the target material. Is it very difficult to overcome the ambiguity to learn brdf parameters of various materials? Would you like to share your knowldge and experience about it?

I see. Thank you!
