Re: ABg BSDF?

I'm getting more and more interested in the ABC BSDF model. Are there any freely available papers on the web? Where can I find a paper with the derivation of the model (even if not free)? the ABC BSDF model fits much better near the transition angle than the ABg, so I prefer it. What is the transiti...

To me, "ompf!" is the feeling I get when I see a real good and fast real-time renderer. In the past, they were simple ray tracers and today, they are path tracers. Maybe we should start imagining meanings to the OMPF acronym. My contribution: "On Multiple Probability Functions". That feels familiar,...

Looking for Nearest Neighbor BVH splitting algo

I recall an article that was discussing a BVH splitting algorithm that whent along the following lines: 1 - Pick any two primitive 2 - Compute two centroids from those two triangles 3 - Gather two lists of all the primitives that are nearest those two centroids 4 - If the list members changed since ...
