Distributed Multi-User Urban Simulation

Abstract

The objective of the research project is the importation, representation and 3D navigation of a large-scale city model. The model will be the backbone for the construction of the proposed Virtual Dublin project. The research & design carried out was aimed to identify issues in distributed multi-user Virtual Environments (VE). A simulation was created which demonstrates the many benefits of the proposed architecture including the following ? 3D Rendering: Level of Detail its importance and benefits towards acceptable response times ? Distributed Database: Provides polygonal mesh data and removes the need for replicated data. ? A Multi-tasking Environment: Allows for the required multiuser activities ? Dead Reckoning: Reduces the network traffic required contributing towards quicker response times and more up to date rendering. The subsequent performance evaluation identified areas for further development and future work.
