Systematic representation and application of a 3D computer-aided garment construction method - Part II: spatial transformation of 3D garment cut segments

Purpose - To establish a method of transforming the 3D cutting patterns constructed and modelled into 2D patterns, excluding the fabric parameters. Design/methodology/approach - Three methods have been developed for transforming 3D cutting part segments into 2D segments. They are based on the computer-based application of the mathematical models developed. The mathematical models differ in their concepts and the application in a particular manner of transforming the 3D segments. Complex spatial matrix transformations have also been developed and used to further transform the 2D segments into the plane of chained 2D cutting pattern segments. Findings - Two-dimensional cutting patterns have been defined for the 3D garment model, initially constructed on a computer-generated body model. Research limitations/implications - The method has been developed on an example of a 3D garment basic cut construction of a single article of clothing. However, the same principles can be applied and developed for any garment basic cut. Practical implications - The mathematical models developed can be used in a new computer-based application for the 3D garment construction and the development of the 2D cutting patterns, matched to individual physical characteristics. Originality/value - The most outstanding property of the method developed is the possibility of gradual transformation of 3D cuts into 2D ones, with no need to define physical-mechanical properties, of the fabric used and no need to introduce fabric drape. The newly created 2D cutting patterns are of outstanding quality and preciseness.
