Computer animation physics or game physics involves the introduction of the laws of physics into a simulation or game engine, particularly in 3D computer graphics, for the purpose of making the effects appear more realistic to the observer. Typically, simulation physics is only a close approximation to actual physics, and computation is performed using discrete values. Additionally, games may intentionally deviate from actual physics for gameplay purposes; a common example is allowing the player to double jump when there is nothing to jump from, or changing the values of certain physical parameters, such as the amount of gravity present.
