The purpose of this paper was to develop an individual prototype garment pattern based on  3D body scanning data. Firstly, the cross-sections of scanning data were preprocessed by three methods, including re-sampling, symmetrising and convex hull calculating. Secondly, NURBS modeling technology was adopted to create a basic garment model based on the curve network. According to different traditional flat prototype patterns, the corresponding feature lines are defined on the models through calculating the intersection curves of the body surface and local planes. Finally, three 3D garment models were subdivided by different cutting methods and the advancing front triangulation method. Surface flattening based on the energy model was adopted to generate the corresponding 2D patterns. In order to analyse the error, the area and length of the 3D and 2D patterns were calculated and compared, respectively, the results of which promote the practicability of the 2D pattern design system in MTM garment production through 3D CAD technology.

Abstract:

 The purpose of this paper was to develop an individual prototype garment pattern based on  3D body scanning data. Firstly, the cross-sections of scanning data were preprocessed by three methods, including re-sampling, symmetrising and convex hull calculating. Secondly, NURBS modeling technology was adopted to create a basic garment model based on the curve network. According to different traditional flat prototype patterns, the corresponding feature lines are defined on the models through calculating the intersection curves of the body surface and local planes. Finally, three 3D garment models were subdivided by different cutting methods and the advancing front triangulation method. Surface flattening based on the energy model was adopted to generate the corresponding 2D patterns. In order to analyse the error, the area and length of the 3D and 2D patterns were calculated and compared, respectively, the results of which promote the practicability of the 2D pattern design system in MTM garment production through 3D CAD technology.
