Harvey, D.Arnold, D. B.Day, A. M.2015-11-112015-11-1119991017-4656https://doi.org/10.2312/egs.19991025We describe many of the considerations required when designing and developing a distributed virtual environment for urban modelling, paying particular attention to its application to virtual heritage. We also describe the possibility of using a specially defined set of scenery and building primitives to reduce the amount of data that needs to be transmitted to recreate the virtual urban environment on the observer’s computer.
