This paper reports on a project, called CADwalk, for the three-dimensonal display of garments on commonly used PCs. The basic idea is to show a customer in a taylor's workshop, in a made-to-measure shop or in a designer studio how she or he looks in the new clothes, before the cloth is cut. This contribution therefore deals with problems of constructing realistic computer models of the customer, of scaling anthropometrical figurines, of algorithms for modelling two-dimensional patterns onto 3D-figurines. The name of the project is derived from CAD and catwalk.
