Digital Molecular Matter (DMM) is a proprietary middleware physics engine developed by Pixelux for generating realistic destruction and deformation effects.

[1] 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 include: The DMM tools and middleware were developed for film and game effects by Pixelux Entertainment over a 6.5 year period starting in 2004.

From 2005 through 2008, Pixelux's real-time version of DMM technology was exclusive to LucasArts Entertainment[31] as a part of the Star Wars: The Force Unleashed (TFU) project.

[32] The FEM system in DMM utilized an algorithm for fracture and deformation developed by University of California, Berkeley professor, James F. O'Brien, as part of his Ph.D.
