Modeling virtual garments is known as a very laborious process, which includes designing 2D patterns, positioning, and sewing them in 3D, performing a physically-based simulation, and then iteratively adjusting patterns and parameters, repeating the process until the expected effect is achieved. The aim of this paper is to make a 2D pattern and 3D simulation of a men's shirt. First, the computer construction of the men's shirt model was made on a sketch-based, i.e. a 2D pattern is developed. Secondly, 2D pattern is developed by flattening 3D surface patches, then a 3D fine garment is formed directly based on the information of sewing relations and correspondence between 3D surfaces and 2D patterns. The method is able to design 3D garments and 2D patterns efficiently and accurately.

We describe a simple new CAD operator that allows draping of given 2D patterns onto the surface of a 3D mold. The 2D pattern is any closed, connected polygon or a polygonal approximation of a shape bounded by curves. The mold is typically described in terms of any standard surface representation scheme, such as NURBS or B-Splines. The draping is achieved by mapping skeletal lines on the 2D pattern onto corresponding geodesic curves on the 3D surface. If the mold surface is developable, our method gives a draping with zero distortion. A useful application in the CAD of footwear is demonstrated as a motivation for this work. A simple software program has been implemented to test the operator, and examples are provided to demonstrate its use.

AbstractMass spectrometry–based imaging (MSI) has emerged as a promising method for spatial metabolomics in plant science. Several ionisation techniques have shown great potential for the spatially resolved analysis of metabolites in plant tissue. However, limitations in technology and methodology limited the molecular information for irregular 3D surfaces with resolutions on the micrometre scale. Here, we used atmospheric-pressure 3D-surface matrix-assisted laser desorption/ionisation mass spectrometry imaging (3D-surface MALDI MSI) to investigate plant chemical defence at the topographic molecular level for the model system Asclepias curassavica. Upon mechanical damage (simulating herbivore attacks) of native A. curassavica leaves, the surface of the leaves varies up to 700 μm, and cardiac glycosides (cardenolides) and other defence metabolites were exclusively detected in damaged leaf tissue but not in different regions of the same leaf. Our results indicated an increased latex flow rate towards the point of damage leading to an accumulation of defence substances in the affected area. While the concentration of cardiac glycosides showed no differences between 10 and 300 min after wounding, cardiac glycosides decreased after 24 h. The employed autofocusing AP-SMALDI MSI system provides a significant technological advancement for the visualisation of individual molecule species on irregular 3D surfaces such as native plant leaves. Our study demonstrates the enormous potential of this method in the field of plant science including primary metabolism and molecular mechanisms of plant responses to abiotic and biotic stress and symbiotic relationships.

The purpose of this study was to provide the reference information for current and potential users of apparel 3D CAD system by studying the functional characteristics of apparel 3D CAD study. The apparel 3D CAD system of Optitex, V-Stitcher and DC-Suite was selected for technical compara tive study.The results were at follows: 1. Three systems are similar in basic 3D system configuration and working flow. 2. In configuring a module, Optitex and V-Stitcher separate a 2D pattern and a 3D simulation, whereas DC-Suite configures a 2D pattern and a 3D simulation in one system. 3. In Optitex, a 3D Runway system performs 3D simulation works linked with its own 2D pattern - making software, Optitex PDS, after the 2D pattern is made. 4. In case of V-Stitcher, 2D pattern making is done linked with Gerber Pattern CAD and a 3D simulation proceeds. 5. DC-Suite was developed based on 3D simulation technologies, different from other systems. It includes its own 2D pattern-making technologies.
