随着网络技术的高速发展，网上在线试衣正成为人们服装消费的新方式。目前网上在线试衣是以二维为主，缺乏全方位展示，还有一些基于建模渲染的三维展示系统，但由于制作复杂，成本高以及色彩还原差等问题，其实用性不高。为此，提出基于Flash的三维在线试衣系统，使用照片为素材制作衣服的三维展示，此系统具有很高的实用价值。

With the rapid development of network technology，online fitting is becoming a new consumption of clothing for people．Online fitting is almost based on 2D until now，and is lack of all-round display．There are some 3D fitting systems based on modeling and rending，but they are too complex to produce，high cost and poor color reproduction，so they are not effective．Therefore，this paper puts forward 3D online Fitting System based on Flash．It uses photographs for 3D display of clothes．This system has a high practical value．
