Collaborative 3D Visualization with CSpray

As networking technology brings us into the information age, 3D and multimedia applications become more prevalent and the emerging norm. Improvements in communication infrastructure also allow us to explore the realm of group interaction and collaboration over the information superhighway. Our work focuses on providing a small group of geographically distributed scientists the means of sharing their data and interactively creating and analyzing visualization products. This allows for shorter turn around time compared to more traditional means which in turn allows for greater research productivity. The key features of our system include: different levels of information sharing, % enforces permission on different levels of sharing, incremental updates to reduce network traffic, % matches service levels according to client's resources, an intuitive floor control strategy, a built in session manager to handle participants who either join late or leave early, and a host of collaborative 3D visualization aids. An added feature is that while the system is designed for small group collaborations, it can also be used for briefing a larger audience. These features are included in the \cspray\ collaborative 3D visualization system.
