摘　　要：TGS Open Inventor是面向对象的API,用于开发交互式三维图形应用程序.用OpenInventor开发虚拟现实应用软件,如果采用模型简化技术,在动态显示大场景时,能实时或近于实时地显示大模型.对于图形API来说,这是一个很好的特性.介绍了TGS Open Inventor实现模型简化的两个部件:So Simplifier和So-SimplifyAction,并给出一个已用于实际虚拟现实软件的程序段,说明类SoSimplifier、SoSimplifyAction的使用.TGS Open Inventor is an object oriented toolkit for developing interactive 3D graphics applications. With model simplification in application development, very large 3D models can be displayed in real or near real time by TGS Open Inventor. The article introduces two components for the model simplification： SoSimplifier and SoSimplifyAction in TGS Open Inventor and presents a short program to demonstrate the features of its use.
