# UnityNativeCollision #
This project is an experimental C# implementation of polyhedron SAT collision and intersection for the Unity game engine. It's specifically designed to be compatible with Unity's Burst Compiler for performance.
##### Acknowledgments:
The math is ported to C# from the C++ BounceLite project by Irlan Robson (zLib License) and adapted for Unity's new Math library and Burst Compiler requirments: https://github.com/irlanrobson/bounce_lite
The SAT implementation is originally based on the 2013 GDC presentation by Dirk Gregorius and his forum posts about Valve's Rubikon physics engine:

##### Features:
* Generation of native half-edge mesh from Unity Meshes.
* Fast convex polyhedron face/edge boolean collision detection.
* Polyhedron intersection manifold generation (via Sutherland-Hodgman clipping)
* Burst compiled jobs for single and batch collision operations.
* Experimental bounding volume hierarchy.
* NativeBuffer collection able to run off stackalloc.
Note: Project was created with Unity 2019.2, older versions may not work.
##### Performance:
##### Contact Visualization:
View a fast version of the contact for physics calcluations. This mode a processes a minimal set of geometry, just enough to move colliding objects apart. Versus the full intersection mode, which needs to clip every face for visual/mesh creation purposes.
