基于VRML和JavaScript的动画控制机制

摘要

VRML (Virtual Reality Modeling Language) is a multi-user interaction the INTERNET and WEB hyperlind, the computer platform-independent network virtual reality modeling language[4] . Currently based on the VRML virtual reality animated simulation of control mechanisms are based on general- purpose 3D software or Flash production, this mechanism is feasible to scene entities less control logic is simple, but complex virtual scene entities more control logic situation will lead to jitter the scene, the program is running slow,lack of flexibility,as well as the program is to large,etc. ,so that the simulation process is smooth and correct operation.%VRML (Virtual Reality Modeling Language)是一种用在Internet和Web超链接上的多用户交互的、独立于计算机平台的网络虚拟现实建模语言.目前基于VRML的虚拟现实动画仿真控制机制都是采用通用3D软件或Flash制作的,这种机制在场景实体较少或控制逻辑简单时是可行的,但对于虚拟场景实体较多且控制逻辑复杂的情况,会导致场景抖动、程序运行缓慢、灵活性不足以及程序过大.就上述问题,使用VRML与JavaScript结合的方法利用JavaScript构建仿真器直接驱动VRML场景,研究了实验过程的仿真控制,解决了场景抖动、程序运行缓慢、灵活性不足以及程序过大等情况,使仿真过程能够平稳、正确地运行.
