基于VRML的3D校园漫游导航系统的设计实现

摘要

Taking a certain college campus as the example, in the paper we present the specified design of a campus 3D walkthrough and navigation system with interactivity function of position guidance, and introduce how to realise the walkthrough environment of the system, discuss how to achieve the real-time interaction with VRML by using SAI, all are illustrated by the implementation of navigation with example. The system has got satisfied effect, and has the promotion role on enriching the interactive diversity of VRML afterwards.%以某大学校园为例,详细设计一个具有位置导航等交互功能的3D校园漫游导航系统.介绍如何具体实现系统的漫游环境,探讨如何使用SAI实现VRML环境的实时交互,并以导航功能的实现举例说明.系统取得了良好的效果,对以后丰富VRML环境的交互功能具有推动作用.
