摘　　要：为了有效地降低分布式虚拟环境中的网络通信量,本文提出了一种基于四叉树的兴趣管理方法。该方法将虚拟环境中的实体注册到以四叉树表示的地理网格上,通过遍历感兴趣区域内的注册实体列表,快速查找到当前虚拟实体感兴趣的其他实体,减少了虚拟实体间不必要的网络通讯,实现了对网络中数据的有效过滤。In order to efficiently reduce the total network traffic in distributed virtual environment, this paper provides an interest management approach based on quadtree. The approach, which registers virtual entities to geographical grid presented by quadtree, can rapidly find other virtual entities interested by the current virtual entity through traveling the registered entity lists in the area of interest, thus efficiently reducing unnecessary communication among virtual entities and filtering data in network.
