Fast Ray Sorting and Breadth-First Packet Traversal for GPU Ray Tracing
We present a novel approach to ray tracing execution on commodity graphics hardware using CUDA. We decompose a standard ray tracing algorithm into several data-parallel stages tha...

Faster incoherent rays: Multi-BVH ray stream tracing
High fidelity rendering via ray tracing requires tracing incoherent rays for global illumination and other secondary effects. Recent research show that the performance benefits fr...

Understanding the efficiency of ray traversal on GPUs
We discuss the mapping of elementary ray tracing operations-acceleration structure traversal and primitive intersection--onto wide SIMD/SIMT machines. Our focus is on NVIDIA GPUs,...

Interactive Glossy Reflections using GPU-based Ray Tracing with Adaptive LOD
We present an interactive GPU-based algorithm for accurately rendering high-quality, dynamic glossy reflection effects from both HDR environment maps and local scene objects. Our ...
