Abstract: The paper describes the development of a high-performance system for visualizing complex scientific models in real-time. The architecure of the system is a client/server model, in which the simulator generates lists of 3D graphics objects in parallel to the simulation, from where they are sent to a streaming server. The server transfers the 3D objects to viewer clients. Clients communicate over a second connection with each other, which adds the ability to perform collaborative tasks. An application related to computational fluid dynamics is specified where such a tele-immersive system can be used. The approach differs to other solutions because it offers a large set of graphics primitives for visualization, and it is optimized for distributed, heterogenous environments.
