Abstract

A physics engine executed on a processor to simulate real-time rigid body dynamics of a simulated physical system with permissive penetration functionality is provided. The physics engine may be configured to iteratively loop through a collision detection phase, solving phase, updating phase, and display phase. When a penetration between a pair of bodies is due to an initial penetration from a prior collision detection phase, the physics engine may permit the initial penetration between the pair of objects during the current solving phase by not applying a bias or position change to correct for the initial penetration. Also the physics engine may be configured to detect geometry changes and modify the initial penetration distance accordingly.
