The study is an attempt to compare the numerical model of dress: "stitched virtually" on a digital avatar issued from the body scanner and its “scanned” real form made for the same user in order to prove a proper design and garment fit to the given user morphology. Keywords: 3d body scanning, proceedings, format 1. Introduction Design and modeling of forms of clothing is a tedious process and requires the designer experience and years of practice. Manual exercise and gradation of clothing, sewing prototypes to validate the modeling in order to match the product to the figure, as part of the preparation process of production, occupy a significant part of the time it takes to process the production of clothing. This means that the process of preparing production carried out traditionally it generates large losses both financial and time. The current trend influenced by dynamic changes in fashion requires manufacturers to quickly adapt new models or colours. The use of CAD/CAM software in garment industry reduces and streamlines the process of garment production preparation. Computerization of this industry is also reflected in the increasingly wider use of 3D scanners [1, 2] for non-contact measurement of the human body. Avatar retrieved from the scanning process can be used in the virtual simulation of garment, Internet, and ultimately on the purchasing of tailored garment. The current trend towards dynamic changes of fashion requires the manufacturer to quickly adapt new models or colors. 2. Methodology The aim of the study was to evaluate the applicability of 3D garment prototyping in implementing a virtual simulation of the garment to garment production process on the example of Lectra software. Our assumptions take into account that the use of CAD software implementing virtual garment simulation to the process of preparing garment manufacturing at the present stage of advancement of technology cannot replace, in some cases, these traditional prototypes sewn to validate the design and modeling, the accuracy of the selection of materials and accessories, as well as the quality of the process. However, it represents a useful tool to assess the correctness of the design or selection of the size of the garment to the body. The work attempts a visual comparison of the product " virtually stitched " for scanned avatar of wearer and the garment prototype sewn and tried-on by the same wearer in reality. 2.1. Scope of work Our study included several stages where we makes a prototyping process in the virtual environment employing 3D body scanner and software solutions of CAD system, as well as the part of industrial prototyping process usually realized in manufactory, mentioned below: • Dress model designed in Kaledo software, • Numerical avatar generated in 3D scanning process by TC2 scanner, • Fabric parameters of chosen fabrics: cotton and polyester analyzed by simple metrological tests, • Patterns of dress designed and modelled, based on the basic method of woman blouse employing Modaris software, 5th International Conference on 3D Body Scanning Technologies, Lugano, Switzerland, 21-22 October 2014 - 66 -
