A couple questions:
- How should one go about implementing BRDFs and integrating them with the existing system? From the Siggraph slides ( http://blog.selfshadow.com/publications/s2013-shading-course/karis/s2013_pbs_epic_notes_v2.pdf ) it looks like you’re using Cook-Torrance, I’d like to implement Ashikhmin-Shirley for example, and Penner’s pre-integrated skin shading too.
