Abstract: As far as fabric model is concerned,some are quite complicated,can not achieve real time display;others only pay attention to explicit appearance,can not reflect the real attribute of the fabric.This paper brings forward a method in the virtual reality environment.It can both reflect the real attribute of the fabric and achieve the effect in the real time.According to the relationship of garment and mannequin,garment characteristics were collected on the 3-D body,and were used to erect three-cornered surfaces according to some rules.Using VRML(virtual reality modeling language) to build 3-D garment configuration,then fractionizing the garment configuration in loop arithmetic.Velvet garment model can be got in VRML environment.The Eon and VB were used to exploit the virtual reality exhibition system.Transmit the garment model and body model into the system,and realize the aim of 3-D garment showing and trying on.
