Foil 173 Avatars

From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 97. by Zeynep Ozdemir(Geoffrey C. Fox)


An avatar is a symbolic-virtual-world representation of a real-world person in virtual reality. Using an avatar, the real-world person moves through the virtual world, seeing what the avatar sees, and interacting by telling the avatar what to do. In a multi-user virtual reality environment, each user in the environment chooses a 3-D shape as a represantative in the VRML world.
A description of an avatar can be divided into two sections:
  • what an avatar looks like
  • how an avatar can move
The movement features of the avatar are primarily controlled by the NavigationInfo node.
