ABSTRACTA 3D GARMENT DESIGN AND SIMULATIONSYSTEMFunda DurupınarM.S. in Computer EngineeringSupervisor: Asst. Prof. Dr. Uğur Güdükbayg uuJuly, 2004In this thesis study, a 3D graphics environment for virtual garment design andsimulation is presented. The proposed system enables the three dimensionalconstruction of a garment from its two dimensional cloth panels, for which theunderlying 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 isimplemented applying a physically-based approach. As well as the simulation ofthe draping of garments, efficient and realistic visualization of garments is an im-portant issue in cloth modelling. There are various material types and reflectanceproperties for fabrics. We have implemented a number of material and renderingoptions such as knitwear, woven cloth and standard shading methods such asGouraud shading. Performance results of the system are presented at the end.Keywords: garment design, garment simulation, fabric rendering, physically-based modeling.iii
