A method to design the function of the brassiere cup shape as developable surfaces and its developed shape using Gaussian Process Regression is proposed. A developable surface, which is generated by sweeping a straight line along a three-dimensional curve, can be seen many products such as ships, buildings, clothes, and so on. The shape has not only its aim which can be formulated but also that which cannot be formulated such as creativity. In this paper, we focus on a brassiere cup. A brassiere cup is composed of several patterns and the cup shape is designed by repeatedly making paper cup model and then checking its three-dimensional shape. For improvement of design efficiency of brassieres, such trial and error must be reduced. The difficulty of the design process is caused by the function of a brassiere cup. Its function, such as to enhance woman’s breast size, et.al., is difficult to formulate and not correlate its three-dimensional cup shape. In this paper, we aim to predict the function of brassiere cup from its cup shape for efficiency of design process of a brassiere cup. First, we formulate the cup shape as developable surface using differential geometry. Then, we proposed a method to parameterize a set of function which characterize the surface using Gaussian Process Regression. Finally, we experimented our proposed method when the evaluated value using its volume and size of the cup is given.
