摘要
VRML可用于构建基于Web的虚拟工厂。以一虚拟炼油厂为例,探讨了虚拟工厂复杂大场景构造的相关优化技术。提出的具有工业特征的原型节点可避免典型场景单元的重复开发;提出的管头定位法有利于各种复杂要求的管线铺设。设计了一视点跟踪节点,解决了复杂大场景的浏览定位问题。
VRML（virtual reality modeling language）can be used to build up virtual factory on Web. As an example of a virtual oil refinery, some optimization technology used in construction of complex vast scene is discussed. A series of prototype nodes with industrial characteristics are proposed to avoid repeated development of typical scene units. Based on a method of positioning by the nodule of pipeline, various pipeline laying can be conveniently realized. And a new viewpoint track node is designed also to solve browse orientation in complex vast scene.
