基于VRML-PHP的博览园虚拟系统设计与实现

以开发效果逼真、浏览快速的虚拟博览园漫游系统为目的,通过比较分析,采用3DS MAX建模,VRML增强其交互功能,在此方案下开发了博览园虚拟漫游系统,阐述了创建虚拟场景和用VRML实现交互的方法和步骤;提出VRML与PHP相结合动态生成及编辑虚拟场景、对象的方法,并阐述了具体实现过程及相应后台操作;综合运用多种优化策略对文件进行了优化。实际运行表明,由上述方法设计实现的网上虚拟博览园漫游系统浏览速度快、仿真效果逼真。

Roaming exhibition garden system based on VRML-PHP

Aiming at developing the exhibition garden roaming system with vivid effect and fast brow sing speed, a roaming system plan was presented, through the comparative analysis, by adopting 3DS MAX modeling,and strengthening its interactive function with VRML. The methods and steps to create virtual scene and to realize interaction with VRML were elaborated;the combination of VRML and PHP was proposed,which could generate and edit virtual scene and object. A concrete implement process and a corresponding background operation were expounded;many kinds of optimization strategies were synthesized to optimize the document. Based on above design methods, a virtual exhibition garden roaming system with quick browsing speed and the lifelike simulation effect was realized.
