Abstract

In curve design, understanding macroscopic feature that emerges from the combinations of shape elements and controlling it are important. However, it is difficult to understand macroscopic feature using conventional shape-information displayed in computer aided design system. On the other hand, trial and error is required in order to create curved profile reflecting macroscopic feature imaged by designer. We proposed shape-generation method using curvature integration and genetic algorithm, and applied it to the design of automobile side-view. Moreover, the index using multi-resolution representation was proposed in order to consider the influence of resolution on macroscopic feature. As a result, it was confirmed that the control of macroscopic feature in consideration of resolution was possible using proposed shape-generation method and the index. In the present study, it was shown that the possibility of new design-support in curved profile using them.
