16、 the vast online fashion market, including the internet, smart phones, smart TVs, and virtual fittings at bricks-and-mortar stores. Meanwhile, the increased demand for ubiquitous fashion business services is encouraging efforts to innovate with regard to the traditional processes of planning, produc

17、tion and sales. The use of digital technology in the modern international apparel industry is leading to the use of three-dimensional information for fashion products. These products reflect appearance, design and texture characteristics of garments. It is envisaged that consumers will be able to go

18、 online anytime, anywhere, to try on clothes, evaluate the style and fit and place orders. Despite such advances, there is no International Standard related to virtual garments.The purpose of this International Standard is to specify the data attributes and formats required for the creation of virtu

19、al garments, facilitating clear and synchronized communication of terminology.This International Standard provides a platform that unifies specified vocabulary and terminology for the development of virtual garment systems. In addition, online consumers, fashion designers, manufacturers and retailer

20、s will be able to become familiar with and make use of this vocabulary.NOTE Measurements of the body and garments are in millimetres (mm). Upward direction corresponds to the +y-axis (height), a leftward direction to the +x-axis (width), and a forward direction to the +z-axis (depth). The origin of

21、body and garment is X = 0, Y = 0, Z = 0 in local coordinates; the common import/export formats for body and garment is dxf format.

22、l Standard defines the terms that are commonly used for the digital fitting system. The digital fitting system includes virtual fabric, virtual fabric properties, virtual garment pattern, virtual garment pattern properties, virtual sewing line, virtual garment, and virtual garment simulation of a vi

27、al sewing is shown in Figure 2.Note 2 to entry: For each pair of patterns to be sewn together, a pair of virtual sewing line segments is defined. The pattern pieces are then arranged in a space and the points (2.2.1.1) on each pair of line segments are pulled together through physical simulation. Th
