....have been made to add VR interfaces to AVS[10] however these extensions only display the final visualization on a VR device thus limiting the users interaction with the data. Immersive Scientific Visualization systems like Cosmic Worm[11] Virtual Wind Tunnel[12] CAVEvis[13] and CAVEstudy[14] have been developed to take advantage of the rich interface the CAVE provides. However these systems are not collaborative. They do not allow a user to share his her view with a remote user. If a group of research scientists wish to collaborate during a data visualization session they would have ....

....project (which is part of the Dutch Robocup initiative) we have developed an interactive and collaborative visualization system for multi agent systems, in particular robot soccer. Our system allows human users in CAVEs at different geographic locations to participate in a virtual soccer match [37, 43]. The user in the CAVE can navigate over the soccer field and kick a virtual ball. In this way, the user interacts with a running (parallel) simulation program, which runs either on an SP2 or a DAS cluster. In general, many other scientific applications can benefit from such a form of high level ....

....actual source code of the simulation program by inserting probing and analyzing instructions. In some cases this is not even possible, as the source code is not available, or altering the source would introduce erroneous behavior. For VIRPI, this problem is addressed by coupling VIRPI to CAVEStudy[9]. CAVEStudy wraps an unaltered remotely running stateless simulation program, and presents a simple programming interface to the user in the VR environment. This way, the user can connect buttons and sliders in the virtual laboratory to parameters of the simulation, and read out the data from the ....

....running on a remote computer. It allows nonexpert users to use virtual reality environments as a measuring tool next to a visualization tool. Furthermore, the system does not alter the simulation program (as this is not always possible) but interacts with the simulation s original input and output [19]. With the system, we address virtual measurement paradigms, comparison with other steering methods and special issues that arise, like calibration and tolerance of measuring in VR. To test the system, we study two relatively simple simulations, a charge recombination simulation, and an idealgas ....

....the intermediate results as output. Our main conclusion is that no environment provides the functionalities needed for an immersive steering and measuring environment, given that we do not want to modify the source code. Adding measuring functionalities to our VR steering environment CAVEStudy [19] should let the user to explore efficiently his simulation and to get a deeper insight of the studied phenomena. 3. Steering We built a system, CAVEStudy [19] that combines the power and the functionalities of computational steering and virtual reality. Our environment combines both the control ....

....soccer game (which is much smaller) and expand this state locally to 3D images. This is especially important for communication over (slow) wide area networks. In our current and future work, we also study other scientific applications that can exploit interactive and collaborative visualization [19]. Example applications we intend to investigate are simulation of nonlinear systems (e.g. lasers) based on our earlier work described in [13] visualization of molecular dynamics, and interactive visualization of the cornea of the human eye [27, 28] Such scientific applications will exhibit ....
