Hi, I'm looking to apply for a YafaRay (a free raytracer) GSoC project that aims to implement OSL support. I am wondering how this can be achieved. Is there any documentation for the OSL libraries? Having discussed a bit with a YafaRay developer the question seems to be which information needs to be retrieved from a compiled shader and how to get it into a shader program.
I'm also applying for this project, and I want to get in contact with the mentor. My current idea is to create a Yafaray nodeMaterial_t (an abstract class that provides a BSDF and other info) that is implemented in terms of liboslexec. A potential problem is that nodeMaterial_t is called for one sample at a time, while liboslexec appears to expect many points at once.
Rickard: there doesn't seem to be any documentation other than the code itself. The README suggests looking at testshade for an example use of the library.
