Avatar Physics and Genetics

JJ Ventrella

Abstract

A technology for creating avatars (virtual humans), and the principles behind its design are described. Avatars in this system are generated entirely through computer programming. Variation is enabled through the specification of hundreds of parameters, which are treated within a genetic paradigm. Animated motion is achieved through a combination of forward dynamics and parametric motion control algorithms. This paper demonstrates how the design of a virtual human can be achieved through simulation based on natural laws, such as in physics and biology.
