We developed an idea support morphogenesis system that satisfies the designer's image and proposes the form with high mechanical rationality using a Genetic Algorithm. The image of an old system was input in two directions (X and Y). In the new system, the complex forms are created by the image input for three directions (X1, Y1, and Y2) or four directions (X1, X2, Y1, and Y2). The form is defined by control points of a spline curve. The form created by the image input is changed slightly by moving the control points. This system creates various forms by changing the moving quantities of control points and proposes Pareto solutions of image and mechanical rationality. Based on the results, we analyze how the form is changed by differences in the moving quantities of control points.
