Method and computer program product for producing 3 dimensional model data of a garment

A computer implemented method for producing 3-dimensional model data of a garment having a target garment size, the method comprising

• storing, in a computer system, intermediate model data of the garment, the intermediate model data being associated with a base garment size and comprising intermediate geometry data and at least one intermediate texture map having a plurality of elements associated with the intermediate geometry data;
• performing, in the computer system, a semantic segmentation of the intermediate texture map for generating a label map, the label map associating each element of the intermediate texture map to a respective one of a set of segments of the garment, and each segment having an associated resizing rule;
• generating, in the computer system, geometry data for the 3-dimensional model data of the garment by resizing the intermediate geometry data based on the label map, on the resizing rules associated with the segments, on a body model associated with the garment and on two or more scaling factors, each of the scaling factors being associated with a respective portion of the body model;
• and
• generating, in the computer system, a texture map for the model data of the garment based on the intermediate texture map, on the label map, on the resizing rules associated with the segments and on the scaling factors.
