Draft-space warping: grading of clothes based on parametrized draft

摘要

This paper presents a novel framework for garment grading. In CG, an extensive amount of study has been carried out tonclothe human characters, but little attention has been taken to the grading problem itself. For the development of a gradingntechnique, we obtained the insight from the process of drawing the patternmaking draft (sloper) in the clothing field. Notingnthat the draft can be completely determined by supplying the primary body sizes, we abstract the draft construction processnas a computer procedure, which we call the parametrized draft. With the parametrized draft, we develop a grading methodnbased on the draft-space warping, which takes three steps: (i) draft-space encoding, (ii) target draft construction, then (iii)ndraft-space decoding. The proposed grading method can be performed instantly for any given body without calling fornthe user’s intervention. With experimental results, we show that the new grading framework can bring an improvement tongarment grading. Copyright © 2013 John Wiley & Sons, Ltd.
