In curve design, controlling the characteristics of the overall shape is difficult using conventional microscopic shape-information such as dimension. Curvature entropy as calculated by the distribution of curvature was proposed as the macroscopic shape-information, and was confirmed to represent the complexity of a shape. In order to adjust the shape recognition of human beings, a Markov process was introduced into the definition of the macroscopic shape-information. Shape-generation method using the macroscopic shape-information was developed, and was applied to the design of an automobile side-view. Thus, the possibility of curve design-support using the macroscopic shape-information was indicated.
