<P>PROBLEM TO BE SOLVED: To emulate the streaming of animation data over the Internet to a large number of clients, in a broadcast application on a client-server network. <P>SOLUTION: The animation is considered a sequence of states. State information is sent to the clients instead of the graphics data itself. The clients generate the animation data under control of the state information. The server and clients communicate using a shared object protocol. Thus, streaming is accomplished as well as a broadcast without running into severe network bandwidth problems. This approach is used to map a real life event, e.g., a motor race, onto a virtual environment in order to let the user participate in a virtual race against the real life professionals, the dynamics of the virtual environment being determined by the state changes sent to the user. <P>COPYRIGHT: (C)2012,JPO&INPIT |
