Abstract :The importance of data distribution increases in Multi-User Distributed Virtual Environments (DVEs) in parallel to both the complexity of virtual scenes and the number of clients. Main challenges are to load the relevant part of the scene, estimate and render visible primitives by keeping the frame rate fluent, since each user sees different part of the shared scene. In order to achieve the frame rate goal, data distribution should be well managed and optimization approaches based on network and visibility should be applied according to the requirements of each DVE. This is substantially handled by considering the area of interest for each user and estimating visible primitives as early as possible. This paper surveys the research on visibility culling, data management based on area of interest in DVEs and consequently summarizes thirteen implementations in the literature.
