摘要
通过对CAD系统中一些常用的三角形数据交换格式和虚拟现实开发工具包WorldToolKit(WTK)的模型操作功能的分析与研究,提出并实现了在WTK开发环境中读取CAD系统导出的三角面片模型的方法。用VisaulaC++6.0作为开发平台,利用WTK中自定义模型的功能实现模型的生成。该方法实现了虚拟环境中直接使用CAD导出模型的目的。
By the analyse of the triangular surface slices dataexchange formats used regularly in CAD systems and the function of model operation of the virtual reality development tool WorldToolKit（WTK）, it presents a method to realize the import model exported by CAD systems in the virtual environment developed with WTK. This can be realized with visual c ＋ ＋ 6.0 and the function of custom model definition in WTK. The model can achieve the aim of using the model exported by CAD systerms in the virtual environment.
