Supporting Multiple Virtual World on a Single 3D Viewer

Abstract

This paper presents work done to view multiple 3D virtual worlds from a single viewer. The work introduces a change to the communication architecture and memory management of the RealXtend Tundra client viewer to support multiple logical connections. The memory management scheme is based on 'area of interests' was introduced to prevent excessive memory consumption. A 'tab' based interface was added to the user interface to make it easy to switch from one world to the next. Tests show that the network traffic increases linearly with the number of additional words and would suggest the need to modify the protocols so non-essential traffic on non-active connections be reduced. Memory management scheme is quite successful in maintaining the desired memory footprint on the GPU.
