Digital Molecular Matter (DMM) is a proprietary middleware physics engine developed by Pixelux for generating realistic destruction and deformation effects. The offline version can support high-resolution simulations for use in film special effects. The real-time version is designed for video games, and other simulation needs by attempting to simulate physical real-world systems. Unlike traditional real-time simulation engines, which tend to be based on rigid body kinematics, the use of finite element analysis (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 (ice, gummy bear, etc.). In addition, the properties of objects or parts of objects can be changed at runtime, allowing for additional interesting effects.
DMM can be authored or used in Maya or 3ds Max to create simulation-based visual effects.
Academy Award
In 2015 three of the key architects behind DMM, James F. O'Brien, Eric Parker, and Ben Cole, were recognized for their work on DMM with an Academy Award. The citation for the award reads:
To Ben Cole for the design of the Kali Destruction System, to Eric Parker for the development of the Digital Molecular Matter toolkit, and to James O’Brien for his influential research on the finite element methods that served as a foundation for these tools.
The combined innovations in Kali and DMM provide artists with an intuitive, art-directable system for the creation of scalable and realistic fracture and deformation simulations. These tools established finite element methods as a new reference point for believable on-screen destruction.
Platform availability
DMM is available and optimized for Microsoft's Windows, Xbox 360, Sony's PlayStation 3, Apple's Mac OS X, and Linux.
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 running a finite element simulation that computes how the materials would actually behave.
Use
DMM has been used in LucasArts's Star Wars: The Force Unleashed, and was used again for Star Wars: The Force Unleashed II.
Plugins for Autodesk Media & Entertainment's 3ds Max and Maya animation software are also available. The plugin is built into Maya 2012.
DMM has been integrated with Gamebryo, Trinigy Vision Engine, Irrlicht, OGRE and other game engines.
MPC Moving Picture Company has integrated DMM into their internal software pipeline known as Kali.
Movies Using DMM
Several movies have made use of DMM for generating offline special effects. These include:
