Collaborative Volume Rendering in a Distributed Virtual Reality Environment
This paper presents the integration of direct volume rendering algorithms into a collaborative working environment. The integration allows not only to share the same viewings on separated workstations and to use telepointers for communication, but also to classify volume elements during a collaborative session. The assignment of opacities and other material properties is updated for all participants. Furthermore it is possible to modify light sources, to switch on or off depth cueing and to change the current direct volume rendering algorithm during the collaborative session. Based on a distributed and load balanced implementation, navigation in a virtual reality environment is possible. Results of performance measurements with different settings are reported.
