Virtual Humans for Animation, Ergonomics and Simulation

摘要

This project describes state of the art computation speed and control methods needed to portray 3D virtual humans suitable for real interactive applications. Then focus is given to the particular approach taken at the University of Pennsylvania with the Jack system. Various aspects of real time virtual humans are considered, such as appearance and motion, interactive control, autonomous action, gesture, attention, locomotion, and multiple individuals. The underlying architecture consists of a sense-control-act structure that permits reactive behaviors to be locally adaptive to the environment, and a PaT-Net parallel finite-state machine controller that can be used to drive virtual humans through complex tasks.
