This paper aims to describe the development of an interactive body model that can be altered to match individual body perimeter, postures and depth for the purpose of computerized pattern making.
Construction of the posture and depth adjustable body model requires the extraction of ten points, adjustment of coordinate points, linking of points by spline curves, control of section lengths and selectability of three hip types. Front to back depth of the model is adjusted by scaling ratio.
Good results were achieved in modelling back shapes, such as flat shape and stoop shape, and of modelling various hip shapes, such as flat shape and protruding shape. Also the presented body model is able to accurately simulate individual depth of bust, waist and hips. Silhouette comparison between the fully adjusted virtual body model and real body shapes shows an almost perfect match. A primary dialog for altering perimeter, length and depth, and a posture dialog for controlling back and hip shapes was developed.
By making fine adjustments to posture and depth, it is possible to make patterns which result in clothing that not only fits well, but also exhibits other desirable properties. This system could, therefore, be seen as a major step forward in pattern making.
