A Bounding Volume Hierarchy (BVH) acceleration library for three.js that speeds up raycasting and enables spatial queries against meshes. It supports raycasting, distance queries, shape casting, SDF generation, and GPU path tracing on large geometries.

Use cases

• speed up raycasting against large three.js meshes
• perform spatial queries like distance and intersection tests on 3D geometry
• build character movement and collision detection in a three.js game
• generate signed distance fields from meshes
• do GPU path tracing in the browser
• implement lasso selection or triangle painting tools on 3D models
• voxelize or sculpt 3D geometry in the browser

When to choose

• you use three.js and need fast raycasting on high-polygon meshes
• you need spatial queries (distance, intersection, shapecast) against 3D geometry in JavaScript
• you're building browser-based 3D games, editors, or path tracers with three.js

When to avoid

• you're not using three.js or WebGL-based rendering
• you need a general-purpose physics engine with rigid body dynamics
• you need BVH acceleration outside JavaScript/browser environments
