AGEIA views the world of advanced gaming physics as having four distinct parts that all must be addressed by either a hardware or software solution, or both. The first one is fidelity, that accurately and faithfully represents the real world is as much detail as possible. The second feature is scale that simple means the solution must support a large number of physical objects at the same time. If you want an entirely destructible world then the number of objects to track rises exponentially..
