提出了一种支持多用户协同交互的三维虚拟博物馆系统框架。对于3D虚拟博物馆，建筑物（空场景）可以投影到2D多边形。因此，我们可以根据场景多边形的Voronoi图来管理集合和用户的数据。我们可以得到Voronoi图细分的多边形为一些单元，利用邻近特性。我们还建立了一些用户之间的通信规则。本文讨论了如何基于多边形的Voronoi图来计算可见性和检测碰撞，旨在提高虚拟博物馆中协同交互的真实性和一致性。
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.
