An implementation of interactive assistant system for shape creation through the genetic operations

On industrial design, human designer intuitively and subjectively creates the shape. In order to assist this process by artificial system, it is important to suggest the variety of the design candidates. In this article, we propose an interactive design assistant system in the case of bottle or bowl. The initial shape candidate population is made of the user-specified object´s profile curve and the randomly generated ones. When the designer selects a candidate, population is updated to novel one by the crossover and mutation in terms of genetic algorithm. The designer can reach preferable shape on the candidate population and refine this shape by his/herself A proposed framework is implemented on the conventional 3-D modeling software in order to handle the geometric model for following detailed design. Through the case study, the framework demonstrates the applicability to suggest the various shape candidates reflecting the subjective preferences.
