I'm having some difficulty building OpenImageIO on macos (Snow Leopard), as a required pre-requisite for building OSL. The build of the external packages fails because libtiff doesn't build.

Re: Compiling OpenShadingLanguage under Windows

The chunk of code between the '{' and '}' is just C++ (mostly, except for the $ markers of course). Looking at this, the line TypeSpec t (simple, t.is_closure()); doesn't make any sense to me,

Hi guys, After quite some thought I agree that d/dx mod(x,a) == 1 is about about the best you can do, even though it doesn't make sense at the discontinuity. It is possible to make sense of the

Re: Review: fix derivatives of mod()

Well, I'm not sure what to think. The derivatives of mod(x,y) is the same as x most of the time, but at the discontinuity? Not sure what else you could really do since the function isn't

Re: Question about BSDFClosure functions

Well, is Larry's baby. I'm in the group that makes the render using OSL. That's right. Yeah That's more of a question for Larry. I know osl closures are in the roadmap, but he is the one to talk to

Re: Question about BSDFClosure functions

Hey Alejandro! Great to hear from you, I had no idea you were involved in this project. I incorrectly interpreted what would actually be given to the renderer, I thought it would be a single
