| 摘 要： | 介绍了一种适合处理动态场景的交互树。算法利用对象间的逻辑关系组织场景，综合利用面向对象概念和八叉树算法，将场景对象间的逻辑关系存储在交互树中。实际应用表明，该算法在保持八叉树优点的同时可以快速准确地确定交互对象，便于组织动态对象和实现动态对象的运动与交互。

| Abstract: | This paper discusses an method of processing dynamic 3D scene. The method collects objects in 3D scene by their logic relationships and stores these relationships in an I-tree (Interaction tree). The nodes in I-tree which have too many faces will be processed by traditional octree method. It has been proved by practical running that the method can quickly determines current interacting object and has quality for operating dynamic object. The method still contains the characteristics of traditional octrees. |
