Abstract:
1. A computer-based design shape generating apparatus for generating a new design shape of an article by performing a shape transformation process, using a transformation processing device, with respect to a design shape of the article which has been already generated, the apparatus comprising: an input device receiving transformation instructions from an operator; and the transformation processing device performing an operation of the design shape which has been already generated in accordance with the transformation instructions, wherein the input device receives input for designating a shape attribute of the article between a transformation region for which the shape transformation process is to be performed and a maintaining region which maintains its shape, and input of a transformation instruction vector which is defined by a direction and an amount of transformation with respect to the article, and wherein the transformation processing device is configured to: not displace a node located at a boundary between the transformation region and the maintaining region; subdivide the transformation region into a plurality of shape elements; and displace a node defining the shape of the shape elements and belonging only to the transformation region in accordance with the input transformation instruction vector as follows:
