simpleslice

A realtime mesh slicer for the game engine Unity3d, capable of dynamically separating concave objects into multiple parts.

how to use

Simply add the MeshSlicer.cs to your project. The code below shows you how to separate a rigidbody into two rigidbodies.

private MeshSlicer meshSlicer = new MeshSlicer();

private void Update() {
    if (Input.GetMouseButtonDown(0)){
        RaycastHit hit;
        var ray = new Ray(transform.position, transform.forward);
        if (Physics.Raycast(ray, out hit)){ 
            Cut(hit.transform.gameObject, transform.up, hit.point); 
        }
    }
}

private void Cut(GameObject target, Vector3 normal, Vector3 point) {
    var gos = meshSlicer.CutGameObject(target, normal, point);

    gos.Item1.AddComponent<Rigidbody>();
    gos.Item1.AddComponent<MeshCollider>();
    gos.Item1.GetComponent<MeshCollider>().convex = true;

    gos.Item2.AddComponent<Rigidbody>();        
    gos.Item2.AddComponent<MeshCollider>();       
    gos.Item2.GetComponent<MeshCollider>().convex = true;
    Destroy(target);
}
