 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 use of FEA allows DMM to simulate a large set of physical properties. Developers can assign physical properties to a given object (or portion of an object) which allow the object to behave as it 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.

Function

DMM is a physical simulation system which models the material properties of objects allowing them to break and bend in accordance to the stress placed on them. Structures modeled with DMM can break and bend if they are not physically viable. Objects made of glass, steel, stone and jelly are all possible to create and simulate in real-time with DMM. The system accomplishes this by mimicking the effects of stress on real molecular matter. Objects react to stimuli in ways simulating the breaking effects of wood, glass, and semi-permeable substances in real time based on observations of their effects in real-world physics.

Development

The DMM tools and middleware were developed by Pixelux Entertainment over a 6.5 year period starting in 2004. From 2005 through 2008, Pixelux' DMM technology was exclusive to LucasArts Entertainment as a part of the Star Wars: The Force Unleashed

An ARM version of DMM was incorporated by Pixelux into their DMM Touch iPhone/iPad product.

A version of the DMM Plug-In is included by Autodesk in their release of Maya 2012. The DMM Plug-In runs on all versions of Maya on all platforms in both 32 and 64-bit mode.
