Why do objects interpenetrate in this simple collision solver?

The code below is from a Microsoft XNA sample here. This is quite a simple rigid body simulation that ignores many physical effects (such as angular momentum), but it does try to push objects (spheres)...

In Unity3D, what is the relation between inertiaTensor and inertiaTensorRotation?

In unity3d there are two properties on rigidbody that correspond to the moment of inertia tensor. One of them is: rigidbody.inertiaTensor, which I know is the diagonal of the inertia tensor, The ...

Dynamic body implementation

I am writing a 2D game where one of the characters has some very particular requirements. This character is a body with no particular shape (similar to a fluid, but not so much), it has to be able to ...
