Hi, My name is Roman Karpov and I'm 21 year old student from Novosibirsk, Russia. I'm studying programming in my last year at Siberian State University of Telecommunications and Computer Science. I want to participate in the development of the Blender during this summer. I want to improve Cycles performance. I would like to implement SIMD for BVH/triangle intersection. Also, after examining the source code, I found that QBVH not fully implemented and I would like to work on it, but I found on the Cycles wiki page http://wiki.blender.org/index.php/Dev:2.6/Source/Render/Cycles/BVH link to the paper "Faster Incoherent Rays: Multi-BVH Ray Stream Tracing<http://www.eng.uwaterloo.ca/%7Ejtsakok/mbvhrs.pdf>" (MBVH RS). Described in this paper method should be faster that QBVH (it uses idea from QBVH to use more than 2 children for node ). But it is more complex to implement. I wonder, this is good enough idea for GSOC project?
Thanks for answers. _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
