In this thesis study, a 3D graphics environment for virtual garment design and simulation is presented. The proposed system enables the three dimensional construction of a garment from its two dimensional cloth panels, for which the underlying structure is a mass-spring model. Construction of the garment is per- formed through cutting, boundary smoothing , seaming and scaling. Afterwards, it is possible to do fitting on virtual mannequins like in the real life as if in a tai- lor's workshop. The behavior of cloth under different environmental conditions is implemented applying a physically-based approach. As well as the simulation of the draping of garments, efficient and realistic visualization of garments is an im- portant issue in cloth modelling. There are various material types and reflectance properties for fabrics. We have implemented a number of material and render- ing options such as knitwear, woven cloth or standard shading methods such as Gouraud shading in our system. Performance results of the system are presented at the end.

Keywords: garment design, garment simulation, fabric rendering, physically- based modeling.
