Abstract

A system and method for designing a wear article for an object comprises providing a virtual three-dimensional model of the object, including first data representing three dimensions of the object. Virtual two-dimensional patterns representing different portions of the wear article are assembled into a virtual three-dimensional wear article. The virtual three-dimensional wear article includes second data representing three dimensions of the wear article. A material type is associated with one or more of the virtual patterns and the virtual three-dimensional wear article. The material type has third data representing at least one physical property of the material type. In order to display the virtual three-dimensional wear article on the virtual three-dimensional model, the first and second data are compared to determine the non-intersection of the virtual three-dimensional wear article with the virtual three-dimensional object. The virtual three-dimensional wear article is then conformed to the virtual three-dimensional model within constraints imposed by the third data. With this arrangement, the system and method enables the virtual wear article to stretch, flex, sag, etc., on the virtual model to better approximate the real-life fit and look of the wear article on an object during design of the wear article.
