Resizable trouser template for virtual design and pattern flattening

摘要

A novel resizable design platform to execute three-dimensional (3D) design and grading as well as pattern flattening of lower-body outerwear is developed. A set of Point-Cloud data, captured by a modern body-scanner is used as raw material to generate a virtual model, which is further sliced at pre-determined horizontal displacements to extract a set of sectional curves. The extracted curves are modified, made symmetrical as necessary, scaled and programmed to be linked with size databases before using them to generate a new surface, which forms a resizable design platform. It has been found to be possible to use the resizable design platform as a 3D drawing board for the creation of virtual trousers and shorts and for the execution of 3D grading and automatic pattern flattening within the environment of an available computer-aided design system. Hence, the processes of fashion illustration and pattern creation may be combined into a single step. As far as is known, such a resizable design platform for combined virtual design, automatic pattern creation and 3D grading of outerwear has not been previously demonstrated.
