Abstract: Methods and systems for modelling and modifying garments, providing a basis for integrated “virtual tailoring” systems and processes. The garment models provided relate specific design points of the garment to specific body regions in terms of explicit 3D relationship rules, enabling garments to be modified holistically, by a constrained 3D warp process, to fit different body shapes/sizes, either in order to generate a range of graded sizes or made-to-measure garments, for the purposes of visualization and/or garment production. The methods described further facilitate the generation of 2D pattern pieces by flattening 3D representations of modified garments using a constrained internal energy minimization process, in a manner that ensures that the resulting pattern pieces can be assembled in substantially the same way as those of the base garment.
