Abstract

3D Collaborative Virtual Environments (3DCVE) enable geographically distant users to conduct collaborative activities in a shared virtual environment. However, this collaboration involves dealing with some problems related to communication among different locations, such as jitter, latency and packet loss, mainly in Internet-based networks. This paper summarizes a few problems related to data network in the 3DCVE development. It also proposes and implements a Dynamic Adaptive Connection model for distributed cluster graphics communication. The proposed model performs checks on communications among graphics clusters and makes adjustments in communication dynamically using Fuzzy Logic. Some experiments are presented for validation purposes. Finally, we present a discussion about the future potential of the architecture.
