Abstract
Abstract A three dimensional image of a solid form is presented to an operator by means of a stereoscopic display. The operator defines a panel on the surface of the form with a set of bounding seam lines. A polygonal mesh is generated between the seam lines and is manipulated in three dimensions by the operator to achieve a desired surface appearance, including wrinkles, folds, pleats and other details. Manipulation of the mesh is constrained by the mechanical properties of the surface material or fabric being modelled. Surface texture and shading are then mapped onto the mesh to fully render the surface appearance in three dimensions.
