A header-only C++20 library for constructing and traversing bounding volume hierarchies (BVH), with multiple SAH-based builders, a reinsertion optimizer, and robust ray intersection routines. It depends only on the standard library and includes an optional C API and serialization support.

Use cases

• accelerate ray tracing in a path tracer
• build a BVH for triangle mesh intersection tests
• speed up ray-scene intersection queries in a renderer
• construct spatial acceleration structures for 2D/3D/4D data
• optimize an existing BVH with reinsertion
• compare BVH builders by quality and speed

When to choose

• you need a lightweight, dependency-free BVH library in C++
• you want direct control over builder choice and BVH quality
• you need multithreaded high-quality BVH construction
• you want a header-only library easy to drop into a CMake project

When to avoid

• you need a full-featured production ray tracing engine like Embree with SIMD kernels
• your project targets pre-C++20 compilers
• you need GPU-accelerated ray tracing
