Standardizing OSL Closures - The Topic(tm)


Zap Andersson
 

So as mentioned on last weeks OSL TSC meeting, there is a desire to have a default set of closures in OSL that can be supported natively, and on the meeting we said that the set used by MaterialX is a good candidate set.

I've invited Jonatan Stone (Lucasfilm) and Niklas Harrysson (Autodesk) to next TSC meeting to discuss the topic a bit. Both are key contributor to the PBR stuff in MaterialX and are both excited at this idea.

There are some interesting implementation wrinkles to think about, which is why these gentlemen are ideal to help us solve this.

Some "light reading" while we await next meeting:
