中文摘要：

随着3D设计技术的发展,3D GCAD也成为热点,但3D GCAD仍存在诸多难点。3D服装CAD系统是建立在3D人体模型上的尺寸信息提取、服装设计、虚拟试衣、动画模拟及基于互联网的定制、销售和展示等技术的集成。根据对其特征以及技术实现的总结,分析得出3D人体测量技术、3D服装人体建模技术、虚拟服装展示和3D服装展成2D衣片是3D服装CAD关键技术研究的热点,通过比较每种技术总结了3D服装CAD技术的发展趋势。

英文摘要：

Along with 3D design technology development,3D GCAD turns into hotspot,but it faces many difficulties.3D garment CAD system is an integration based on extracting information about the size of 3D human body model,garment design,virtual clothing,animation and Internet-based customization,sale and exhibition and so on.According to the summary of its features and technology achieved,3D human body measurement,3D garment body modeling techniques,virtual fashion exhibition and the conversion from 3D garment into a two-dimensional garment piece are the hot research of key technologies on 3D clarment CAD.
