CAD methods in garment design

Three dimensional Computer-Aided-Design (CAD) technology is gradually

diffusing into the garment design and manufacturing applications. At present, the

apparel industry widely uses two-dimensional CAD tools. It is anticipated that

three-dimensional design tools will be the next evolving technology for the apparel

industry. The basic problems in apparel products design are the fitting problem and

the related 2D-pattern generation problem. The ultimate goal is to design and produce

well-fitted personalized garments for individuals, and the 3D approach is the most

rational approach to be adopted to realize this goal. The 3Dapproach consists of

first paper serves as a cursory review of cloth simulation technology which lays the

foundation of 3D-garment design. The following three papers show techniques for

3D-garment design in a virtual environment. The last paper in this special issue gives

a novel technique to convert 3D-garment pieces into corresponding two patterns.

The first paper is a review paper from Choi and Ko on research problems in cloth

simulation. As a fundamental technique for the design and modification of apparel

items, the physics-based cloth simulation technique is used to generate realistic cloth

motion in real-time. Three technical aspects of cloth simulation are reviewed in this

paper: (1)garment construction; (2) physically based simulation, and(3) collision

detection and response. The technical challenges, namely creating more realistic

the framework presented in this paper integrates the state-of-the- art physical

simulation algorithms with the innovative design tools to provide an efficient and

quality garment design and prototyping procedure.

The third paper describes an integrated environment, which allows designers to

validate their style and design options through the analysis of garment virtual

prototypes and simulation results, so that the number and role of physical prototypes

are reduced. In line with the previous paper, the garment virtual prototyping method

presented in this paper is also physics-based. They define the particle mesh associated

with each fabric panel as a structured 2Dgrid whose coordinates aligned with the

directional anisotropic warp and weft properties of the fabric. The constrained

approach, the 3Dgarment fitting simulation is not required to repeat the entire

simulation for every 2D-pattern modification, the efficiency of the pattern

modification processing is greatly enhanced. Another advantage of the proposed

algorithm is that the mesh topology of the 2D-garment pattern is preserved and thus

simplifies the numerical scheme by maintaining the consistency of the matrix

equation.

In order to determine good fitting two-dimensional flattened patterns from user

defined three-dimensional surface regions, an approach is presented by McCartneyet

al. in the fifth paper. In their algorithm, an orthotropic strain model is adopted to

convert the strain values locked in undevelopable regions to energy functions. These

considered in their paper.

and insights for all papers in this special issue. The papers in the special issue indicate

of physics-based simulation, collision detection, 3D/2D-conversion, and effective

design interface, but we would expect that the complex garment design tasks could be

virtually completed by CAD systems in the very near future.
