unity-tinybvh

An example implementation for tinybvh in Unity and a foundation for building compute based raytracing solutions.

Features

TinyBVH Integration
Leverages tinybvh for efficient BVH and Compact Wide BVH (CWBVH) construction, using a C++ plugin.
GPU Mesh Aggregation
Packs scene meshes into a unified aggregate vertex buffer and triangle attribute buffer via compute shader.
Asynchronous BVH Construction
Uses async readback to transfer mesh data from GPU to CPU, and runs BVH construction in a thread.
Wavefront Path Tracer
A basic compute based raytracer structured like a wavefront path tracer. Includes multiple display mode examples:
- ndotl
- BVH Steps
- Ray Distance
- Normals
- Barycentrics
- UVs
