چکیده

Most axis-aligned bounding-box (AABB) based BVH-construction algorithms are numerically robust; however, BVH ray traversal algorithms for ray tracing are still susceptible to numerical precision errors. We show where these errors come from and how they can be efficiently avoided during traversal of BVHs that use AABBs.

Robust BVH Ray Traversal

Most axis-aligned bounding-box (AABB) based BVH-construction algorithms are numerically robust; however, BVH ray traversal algorithms for ray tracing are still susceptible to numerical precision errors. We show where these errors come from and how they can be efficiently avoided during traversal of BVHs that use AABBs.

Review and Comparative Study of Ray Traversal Algorithms on a Modern GPU Architecture

In this paper we present a chronological review of five distinct data structures commonly found in literature and ray tracing systems: Bounding Volume Hierarchies (BVH), Octrees, Uniform Grids, KD-Trees, and Bounding Interval Hierarchies (BIH). This review is then followed by an extensive comparative study of six different ray traversal algorithms implemented on a modern Kepler CUDA GPU archite...

Exploiting Local Orientation Similarity for Efficient Ray Traversal of Hair and Fur

Hair and fur typically consist of a large number of thin, curved, and densely packed strands which are difficult to ray trace efficiently. A tight fitting spatial data structure, such as a bounding volume hierarchy (BVH), is needed to quickly determine which hair a ray hits. However, the large number of hairs can yield a BVH with a large memory footprint (particularly when hairs are pre-tessell...

Improving BVH Ray Tracing Speed Using the AVX Instruction Set

High performance ray tracing on the CPU requires the efficient utilization of SIMD instructions. Ray packet and ray stream traversal algorithms achieve this by performing computations on multiple rays, nodes, or primitives at the same time. In this paper, we present our approach to optimizing coherent BVH ray packet tracing for the new AVX instruction set, which enables 8-wide SIMD operations o...

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 that are mapped efficiently to the massively parallel architecture of modern GPUs. These stages include: ray sorting into coherent packets, creation of frustums for packets, breadth-first frustum traversal through a bound...
