....Ideally network traffic should be almost constant or grow near linearly with the number of users. Usually, not all the data in the CVE environment would be relevant to a particular user at a given time. This suggests the idea of partitioning the environment into regions (or zones, locales, auras) [1,8,9] that may either be fixed or bound to moving avatars. Events and actions in remote zones need not be distributed and remote objects need not be visualized or might be visualized at a coarse grain level. Most of the traffic is isolated within zones. 3. Ownership: A multi user CVE world is subject ....

....to be transferred over a network can slow down the interaction of the individual user with the shared world in an unreasonable way. And the user may realize only some parts of his her surrounding. A solution for this problem is the subdivision of large virtual worlds into several regions or zones [8]. A major mechanism for reducing the required network traffic among participants of shared virtual worlds is the division of such virtual worlds into regions or cells. The participants receive only update messages on virtual world contents of a subset of cells. Thus, the network traffic can be ....

....using more or less realistic representations. Participants can move about or go from one virtual room to another, share tools, and discuss, in real time, projects or ideas. Examples of three dimensional virtual environments include research prototypes such as DIVE [1] MASSIVE [2] and SmallView [3]. Their acceptance is being boosted by the development of the VRML standard [4] and its incorporation in many Web browsers. Virtual environments can also include videoconferencing facilities. Participants images taken from a video camera then replace the face of user embodiments in the virtual ....

....Broll of the GMD. This is especially true in my research into the selection of the communication topology and data distribution model that would make scalable virtual environments a possibility. Like NPSNET, use is made of IP multicasting in order to realize a scalable communication infrastructure[Broll 1997a] Large worlds are also sub divided in order to reduce unnecessary network messages. However, this is not done in the same way as AOIM s in NPSNET, where the world is sub divided into hexagonal regions(figure 7) Rather, a more generic approach is taken, which allows the sub division of worlds ....

....a prototype implementation of DTWP. In its second version the implementation is realized by a multithreaded shared library. This library includes the DTWP peer component and the DWTP daemons (including the world daemon interface) The DWTP peer component is used by our VRML browser SmallView [3] to connect and communicate with shared virtual worlds. Joining a shared virtual world is realized by specifying the appropriate URL (dwtp: When the world has been downloaded, it is parsed by SmallView for additional downloads (e.g. inlines, textures, avatars, etc. When specified by a ....

....Since VRML is comprehensive and platform independent we use it as the basic scene description language in our prototype. Mechanisms to synchronize user interactions and share object behaviors as well as an approach for an appropriate user representation have been discussed in previous work [4]. In this paper we will present our approach on a flexible network communication architecture for shared virtual environments supporting a large number of participants on the Internet. In the second section of this paper we will compare different types of network connections for shared virtual ....
