摘　　要：VRML是Web上建立三维虚拟模型的标准语言 ,在VRML场景中通过连续地自动控制用户视点的改变达到用户观察场景的角度变化 ,称为视点动画。该文根据控制方式的不同 ,把视点动画划分为主动视点动画和被动视点动画 ,然后分别研究了这两类视点动画的机制和相应的设计方法。VRML is a standard language for building 3D virtual reality model in Web. Automatically and continuously changing user viewpoint will change user observation angle of scene, which is called viewpoint animation. Based on different control mechanism, this paper provides two categories of viewpoint animations which are initiative and passive viewpoint animations. And it studies these two viewpoint animations′ control principle and the corresponding design method. At the end, an example is presented to show effectiveness of the method.
