Optimizing and Recomposing of 3D CAD Model Data in Virtual Environment

ZHANG Wei-wei1,LIU Fang1,2,HU Xiang1,3(1.Institute of Surveying and Mapping,Information Engineering University,Zhengzhou Henan 450052,China;2.73603 Troops,Nanjing Jiangsu 210049,China;3.69028 Troops,Wulumuqi Xinjiang 830000,China)  
3D CAD was applied widely in virtual environment.The model of 3D CAD has complicated structure and lots of redundant information,so it can't be applied to construction of virtual environment efficiently.Aiming at the requiring of data model in virtual scene,this paper brings forward a kind of optimizing and recomposing method of 3D CAD model.This method wipes up the redundant information,predigests files structure and enriches data content.It can improve the performance of virtual environment greatly.
