摘　　要：随着用户对汽车造型要求的不断提高,全球车企车型换代速度随之不断提高,车型研发周期不断压缩,这就对车企造型开发的质量与速度提出了更高要求。伴随着图形学底层算法和计算机辅助设计软硬件的不断发展,一种基于细分算法的“快速建模”(细分曲面建模,亦称subdivision建模)被发明并被运用到汽车造型开发。文章从细分算法的发展历程及原理入手,介绍细分曲面建模在造型开发中的位置、作用及核心优势,最后介绍其具体建模思路及实施方法。With the continuous improvement of consumers'requirements for car styling,the speed of model updating of global car companies is constantly improving,and the model R&D cycle is constantly compressed,which puts forward higher requirements for the quality and speed of model development of car companies.With the continuous development of graphics underlying algorithms and computer-aided design software and hardware,a"fast modeling"(subdivision surface modeling,also known as subdivision modeling)based on subdivision algorithm is invented and applied to the development of automobile modeling.This paper starts with the development process and principle of subdivision algorithm,introduces the position,function and core advantages of subdivision surface modeling in modeling development,and finally introduces its specific modeling ideas and implementation methods.
