Claim 0:
1. 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
generating and storing the intermediate model data based on a set of images showing the garment from a plurality of viewing angles, wherein generating the intermediate model data includes 3D reconstruction for generating the intermediate geometry data and texture mapping for generating the intermediate texture map, and the set of images are one of:
photographs of the garment being dressed on a mannequin or on a person;
rendered images of a CAD model of the garment in a worn state,

wherein generating the intermediate model data is further based on a further set of images showing the garment from a plurality of viewing angles, the images of the further set of images showing the garment with added visually distinctive features, in particular virtual or real patterns and/or stickers and/or tapes, at a surface of the garment, and
wherein generating the intermediate model data comprises
generating auxiliary geometry data by performing 3D reconstruction based on the further set of images; and
aligning the intermediate texture map to the auxiliary geometry data by aligning the intermediate geometry data to the auxiliary geometry data.
