Research on the methods of form semantic about the product design based on NURBS surface technology

This issue combined the theory about history of auto style design, configurations and the semantic of product, through the investigation and study among the people, found out the most impressive distinguish among all kinds of cars; next, analyzing the different semantic relations among the different surfaces which are pieced together into the whole configuration of a car, simulating the surface with NURBS technology in the 3D-modleing software, and to obtain the data from these parameter surfaces. Finally, this issue build a ¿semantic-data corresponding system¿ contains the correspondence of data about surfaces and semantic about surface. To prove the system, the issue finished an auto style design with the data which were get from it, then made a investigation about the impressing when people gave the first sight to the work. The result of the study show us that this system was rational and it worked well in the process of style design because it can provide efficient directions to the designers.
