N2 - We present a performance comparison of bounding volume hierarchies and kd-trees for ray tracing on many-core architectures (GPUs). The comparison is focused on rendering times and traversal characteristics on the GPU using data structures that were optimized for maximum performance of tracing rays irrespective of the time needed for their build. We show that for a contemporary GPU architecture (NVIDIA Kepler) bounding volume hierarchies have higher ray tracing performance than kd-trees for simple and moderately complex scenes. Kd-trees, on the other hand, have higher performance for complex scenes, in particular for those with occlusion.
