Abstract :
This paper describes a system framework of 3D virtual museum supporting multi-user cooperative interaction. To a 3D virtual museum, the building (empty scene) can be projected to a 2D polygon. Hence, we can manage the data of collections and users based on the scene polygon´s Voronoi diagram. We can get the Voronoi diagram by subdividing the polygon into some cells using the proximity characteristic. We also establish some communication rules between users. In this article, how to compute visibility and detect collisions based on polygon´s Voronoi diagram is discussed and this method is aimed to improve the reality and coherence of cooperative interaction in virtual museum.
