Bounding Volume Hierarchy (BVH) is a popular ray tracing acceleration technique that uses a tree-based “acceleration structure” that contains multiple hierarchically-arranged bounding boxes (bounding volumes) that encompass or surround different …

BVH Ray Tracing – Kevin Pick Portfolio - WordPress.com
https://programmerkevin.wordpress.com/bvh-ray-tracing/
My ray tracing implementation utilizes Direct3D’s HLSL compute shaders to produce and traverse a Bounded Volume Hierarchy (BVH) on the GPU. The algorithm used is inspired by NVIDIA’s work in CUDA for ray tracing.
bounding volume hierarchy - Is BVH faster than the …

First, it is important to observe that there are basically two different "classes" of methods for building accelerations structures for ray tracing: 1) space subdivision methods (e.g. BSP, kD-Tree, Octree, etc.); and 2) object subdivision methods (e.g. BVH).
Computer Graphics: Ray Tracing, Space Partitioning, BVH
https://cglearn.eu/pub/computer-graphics/ray-tracing-space-partitioning-bvh
Ray Tracing, Space Partitioning, BVH So far we have rendered our scene via the standard graphics pipeline. That is, we sent the geometry to the GPU, where it was rasterized and each fragment colored. Fragment coloring took into account the light source, material properties and used some lighting model to calculate the color value.

Fast, Effective BVH Updates for Dynamic Ray-Traced Scenes Using Tree Rotations Daniel Kopta Andrew Kensler Thiago Ize Josef Spjut Erik Brunvand Al Davis Abstract Bounding volume hierarchies are a popular choice for ray tracing animated scenes due to the relative simplicity of refitting bounding volumes around moving geometry.

state of the art BVH and kd-tree based systems. We demonstrate our ray tracer on a variety of scenes, and show that it is always competitive with—and often superior to—state of the art BVH and kd-tree based ray tracers. 1 INTRODUCTION High performance ray tracing usually requires a spatial and/or hi-

In contrast, Octrees/K-d trees and other space subdivision, divide the space recursively. A simple picture of an octree given in the paper. 2) The above pictures show another difference. That is, in Space subdivisions we have disjoint sets of space regions or …
