摘　　要：本文提出了一种快速三维建模的方法,即用3DS MAX7．0来完成特殊物体的精确建模,用Outline3D 4．5来整合大场景,用Vrmlpad 2．1来进行后期加工、优化压缩与发布。以建立虚拟原子吸收实验室为例,研究了提高网络浏览速度的几个关键技术,如通过使用Billboard、Background节点、节约线面、优化压缩、降低纹理图分辨率等以优化文件；使用硬件渲染方式使虚拟场景显示快速、平滑。所完成的基于Web的三维虚拟原子吸收实验室场景形象逼真,可使用指定的浏览器插件来浏览,可从多视点观看,具有信息提示,活动门窗,自动漫游等功能和较好的交互性。A fast three-dimensional modeling method is proposed combining with Outline3D 4.5, 3DS MAX7.0 and Vrmlpad 2.1 to build quickly an interactive VRML scene of a virtual atomic absorption laboratory on the Web as the example. In order to optimize the VRML scene file and speed up the surfing of the network, some key techniques have been studied such as using Billboard nodes, Background node, economizing the lines and faces, optimizing the compressing file, reducing the resolution of texture images etc. The special hardware rendering mode is selected to make the virtual scene display fast and smoothly. The finished three-dimensional virtual atomic absorption laboratory on the Web looks like the real laboratory, and can be explored with a certain browser plug-in from different viewpoints, and have functions of information hints, the movable doors and windows, multi-viewpoints, auto-cruising with the better interaction.
