I present a comparative study on GPU ray tracing implemented for two different types of ray-triangle intersection algorithms used with BVH (Bounding Volume Hierarchy) spatial data structure evaluated for performance on three static scenes. I study how number of triangles placed in a BVH leaf node affects rendering performance. I propose GPU-optimized SIMD ray-triangle intersection method evaluated on GPU for path-tracing and compare it’s performance with plain Moller-Trumbore and Unit Triangle intersection methods.
