| 摘要 | This shape data generation method include: setting an input shape that has a simple shape that has a same topology as the target shape for a target shape that is a shape of a transformation target identified from image data; identifying first vertices that satisfy a predetermined condition including a first condition that a normal line of a certain vertex of the plural vertices crosses with the target shape, among plural vertices of the input shape; transforming the input shape so that a first vertex is moved in a direction of a normal line of the first vertex by a first distance that is shorter than a distance up to the target shape; and performing the identifying and the transforming a predetermined number of times while changing the input shape after the transforming as the input shape to be processed. | ||

| 主权项 | 1. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a process, the process comprising: setting an input shape for a target shape that is a shape of a transformation target identified from image data, wherein the input shape has a simple shape that has a same topology as the target shape; identifying first vertices that satisfy a predetermined condition among a plurality of vertices of the input shape, wherein the predetermined condition includes a first condition that a normal line of a certain vertex of the plurality of vertices crosses with the target shape; first transforming the input shape so that a first vertex is moved in a direction of a normal line of the first vertex by a first distance that is shorter than a distance up to the target shape; and performing the identifying and the first transforming a predetermined number of times while changing the input shape after the first transforming as the input shape to be processed, wherein the setting comprises upon detecting that the target shape is a three-dimensional surface with an opening, second transforming a flat input shape in conformity with the opening, and the first transforming comprises fixing an edge portion of the flat input shape that was transformed in conformity with the opening. | ||
