Free-form surface subdivision method for car style design

International Journal of Vehicle Design (IJVD), Vol. 17, No. 3, 1996

Abstract: Bezier patches subdivision and manipulation methods are developed to design 3-D automobile surface models in this study. A program is constructed based on the object-oriented programming technique with the language C⁺⁺. With this tool, the designer can construct the desired car styles started with a basic configuration by subdividing the surfaces and manipulating the continuity between the connected patch boundaries. The local shape control of a region is performed by subdividing a surface. Although the Bezier surfaces arc used, the shortcoming of lack of flexibility in local control can be prevented. This approach also easily avoids cracks between patches and surfaces. Thus, it is suitable for the generation of a 3-D surface model for many engineering applications.
