Objective Analysis of the Drape Behaviour of Virtual Shirt, Part 1: Avatar Morphing and Virtual Stitching

This research addresses an objective approach to analysing the drape behaviour of virtual shirts with varying eases at the chest area and two different lengths. A set of bodyscan data was utilised to identify body measurements of M-sized British men for the purpose of pattern drafting as well as for avatar morphing within 3D CAD systems. Two different sets of pattern pieces (each set comprising 31 pairs of front and back panels with varying ease from 0.0 to 15 cm at the chest area at an interval of 0.5 cm) of sleeve-less men’s shirt were drafted using a clothing CAD system. Size and shape of virtual avatars in two CAD systems were adjusted according to the anthropometry of M-sized British men before simulating pattern pieces on to them utilising the fabric parameters derived from the FAST system. This facilitated the objective analysis of the virtual drape of the simulated shirts with varying ease at the chest girth using three technical parameters namely tension, stretch and pressure. The results and findings will be presented later in part 2 of this paper
