Abstract
A computer-implemented multi-user virtual reality system that erects a networked virtual world for real time interaction amongst multiple participants. A computer-simulation of an animated world is network-distributed amongst participants, e.g., as a virtual world. The simulation accommodates multiple users whose computers are connected by a communications network. The users' computers need not be the same type of machine. Users can interact with one another and with the objects in the virtual world. The properties of objects in the virtual world, such as form, color, and behavior, are displayed on monitors and can be modified in real time while the simulation is running. Modifications to objects are stored and therefore persist, and can therefore bridge across computer system shutdowns and restarts.
