TinyBVHNet

.NET wrapper for the TinyBVH library — a fast, lightweight BVH (Bounding Volume Hierarchy) construction and traversal library by Jacco Bikker.

Multi-targets net48 and net10.0. Ships native binaries for Windows x64/arm64 and Linux x64/arm64.

using TinyBVHNet;
using System.Numerics;

// A single triangle with a ray from above
float[] vertices = { 0,0,0,1,  2,0,0,1,  0,2,0,1 };
using var bvh = new BVH();
bvh.Build(vertices, 1);

var hit = bvh.Intersect(
    new Vector3(0.5f, 0.5f, -1),
    new Vector3(0, 0, 1));

Console.WriteLine(hit.HasValue
    ? $"Hit at distance {hit.Value.Distance:F3}"
    : "Miss");
