This package contains a C# port of the renowned VHACD algorithm, which is widely used in game/physics engines to speed up physics calculations because it can automatically create a set of strictly convex shapes approximating any complex geometry.

In Unity, convex decomposition is required, if you want to have accurate dynamic Rigidbody collisions for a mesh with complex geometry. For more information, refer to the screenshots and the documentation.

This library is specifically made for those who wish to do convex decomposition at runtime on any platform. It's implemented in pure C# and runs on all platforms that Unity supports.

(Fully tested on Windows, WebGL and Android. Looking for beta testers for macOS, iOS & Linux.)

Limitations

• Asynchronous calculation is currently not supported on WebGL.

Scope Limitations

• The asset currently does not contain any editor tooling (e.g. for modifying the colliders or serializing them as assets for later use). For authoring colliders at design-time in the Unity Editor, there are other tools available in the Asset Store that already do a good job at this.
