UnityNativeCollision

This project is an experimental C# implementation of SAT collision and polygon intersection for the Unity game engine. It’s specifically designed to be compatable with Unity’s Burst Compiler for performance.

Features:
  • Generation of native half-edge mesh from Unity Meshes.
  • Fast convex polygon face/edge boolean collision detection.
  • Polygon/Polygon intersection manifold generation (via Sutherland-Hodgman clipping)
  • Burst compiled jobs for single and batch collision operations.

Note: Project was created with Unity 2019.2, older versions may not work.

The SAT implementation is based on the 2013 GDC presentation by Dirk Gregorius and his forum posts about Valve’s Rubikon physics engine:
