Photo-Realistic Rendering and Its Key Techniques on Shoe CAD

This paper introduces a shoe CAD system, used to design 3D shoes by computer directly. By the system, a designer can modify the design conveniently until a satisfactory result is obtained. In the paper, the key techniques of the realistic shoe design and its implementation are presented, including those on 3D shoe last construction, shoe pieces creation, pieces flatting, sewing modeling between pieces, texture mapping and bump mapping controlled by bump image. By using these techniques in our shoe design CAD system, the realistic shoe model can be obtained.
