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。
This paper presents a rapid 3D modeling method that uses 3DS MAX7.0 to perform accurate modeling of special objects, integrates large scenes with Outline3D 4.5, post-processing with Vrmlpad 2.1, optimizes compression and release. Taking the establishment of Virtual Atomic Absorption Laboratory as an example, several key technologies to improve the speed of Internet browsing are studied, such as optimizing the files by using Billboard, Background nodes, saving facets, optimizing compression and reducing the resolution of texture maps; using hardware to render Way to make the virtual scene display fast and smooth. The finished Web-based 3D Virtual Atomic Absorption Laboratory scene is vivid and can be viewed using the specified browser plug-in. It can be viewed from many viewpoints and has the functions of information prompt, active doors and windows, automatic roaming and better interactivity.
