A GPU Raytracing Algorithm Based On BVH Traversal

摘要：

Recently, Ray tracing on consumer level graphics has been introduced. So far, most studies on this topic used the uniform grid or KD-tree as the acceleration structures. In this paper, we present a bounding volume hierarchy acceleration structures and a BVH traversal algorithm on GPU for reducing the number of ray/triangle intersections. Comparing our BVH acceleration structure with uniform grid and KD-tree, we conclude that on the GPU, our BVH traversal technique is faster,simpler and most memory efficient.
