BS ISO 20947-2:2020 pdf free.Performance evaluation protocol for digital fitting systems Virtual garment.
BS ISO 20947-2 1 Scope :This document specifies a method for describing the functions and the method for evaluating the
performance of the virtual garment pattern cutting and clothing simulation modules of digital fitting systerms. This document is applicable to fashion designers and pattern technologists (makers) for generating virtual garment patterns, and testing them on a virtual fit mannequin (fit form).2 Normative references.There are no normative references in this document.3 Terms and definitions

3.1 General 3.1.1 digital fitting system.simulation of a virtual garment pattern or virtual garment over a virtual fit mannequin (fit form) (3.1.2) providing qualitative and/or quantitative evaluation of the fit through analysis of the distribution of,among other things, surface strain, gap between body and garment, tension map, cross section, surface wrinkles, garment balance 3.1.2 virtual fit  annequin (fit form)model used for draping and examining silhouette and fit of a garment in a virtual space used fordigital fitting
3.1.3virtual garment three-dimensional clothing in digital form that exists in virtual space 3.1.4 .virtual garment pattern
shapes consisting of straight lines and closed curves that mark the area of a digitized pattern used on the virtual garment (3.1.3)
Note 1 to entry: Each pattern consists of a contoured and multiple internal lines, which are used to express seams, internal openings, fold lines, and other gar ment characteristics.4.2 Data import a)Function to import three-dimensional virtual fit mannequin (fit form) in file format.b) Function to import two-dimensional virtual garment pattern in file format.c Function to import three-dimensional virtual body.d) Function to specify the material properties of cloth.e) Function to specify the layers.f Function to specify the sewing information.4.3 Digital ftting.Qualitative and/or quantitative evaluation of overall and/or specific simulation garment fit through
analysis of the distribution of surface strain, gap between body and garment, tension map (stress area),cross section, surface wrinkles, garment balance, etc.BS ISO 20947-2 pdf download.
