BVH Construction and Traversal Library

This library is a small, standalone library for BVH construction and traversal. It is licensed under the MIT license.

Features

• Two BVH builders: A fast, single-threaded sweeping SAH builder, and a multithreaded mini-tree BVH builder inspired from "Rapid Bounding Volume Hierarchy Generation using Mini Trees", by P. Ganestam et al.
• A fast and robust traversal algorithm using "Robust BVH Ray Traversal", by T. Ize.
• A fast ray-triangle intersection algorithm based on "Fast, Minimum Storage Ray/Triangle Intersection", by T. Möller and B. Trumbore,
• Can be parametrized on the dimension (e.g. 2D, 3D, 4D BVHs are supported) & scalar type (e.g. float or double),
• Only depends on the standard library (parallelization uses a custom thread pool based on std::thread).
