Digital Molecular Matter

Digital Molecular Matter, better known as simply DMM, is a middleware physics engine developed by Pixelux. It is designed for computer, video games, and other simulation needs by attempting to simulate physical real-world systems. Unlike traditional realtime simulation engines which tend to be based on rigid body kinematics, the novel use of FEA allows for DMM to simulate a more general set of properties. Developers assign physical properties to a given object (or portion of an object) and then at runtime they behave as they would in the real world (e.g. ice, gummy bear, etc.) In addition the properties of objects (or even just parts of objects) can be changed at runtime allowing for additional interesting effects.

DMM can also be used in a slower-than-realtime setup for Maya to ease the creation of physical effects in animations.
