Biomechanical Modeling and Simulation

July 30, 2010
A comprehensive biomechanical model of the human upper body, which simulates 68 articular bones with 147 degrees of freedom; 354,000 tetrahedral finite elements with the appropriate constitutive behavior to simulate the soft tissues; 814 skeletal muscles, each modeled as a piecework uniaxial force actuator; and a dynamic controller that computes the muscle activations necessary to animate the elaborate musculoskeletal system.

The model--created by electrical engineer and computer scientist Demetri Terzopoulos and his colleagues at UCLA's computer graphics lab, uses a complex mixture of math, biomechanics, anatomy, physics and computing, and is the most-detailed biomechanical human model for computer animation yet.
