摘要： A method of converting three-dimensional shape data into cell internal data. The method includes an oct-tree division step of dividing external data including boundary data of a target object into rectangular parallelepiped cells having boundary planes orthogonal to each other by oct-tree division. The method further includes a cell classification step of classifying each of the cells into an internal cell positioned inside or outside the target object or a boundary cell including the boundary data, and a cut point determination step of determining cut points of edges of the boundary cell based on the boundary data. The method further includes a boundary surface determination step of connecting cut points to form a polygon, and determining the polygon as the cell internal data when the number of the determined cut points is no fewer than 3 and no more than 12.

摘要： A principle curvature of a target curved surface S′ and a principle curvature of a corresponding position of a reference surface S are obtained and each part is displayed by being classified into (a) a case where two principle curvatures increase, (b) a case where two principle curvatures decrease, and (c) a case where one of the principle curvatures increases and the other decreases from the difference between the principle curvatures. (a), (b), and (c) are determined as mountain, valley, and twist, respectively, and are displayed in different symbols or colors on an image. Consequently, a different part between two three-dimensional shapes can be accurately grasped, the cause of the occurrence of the error such as a partial curve or the like can be easily found, how much the shapes coincide with each other as a whole can be indicated by an objective numerical value, and the error can be easily determined even if the reference shape is complicated.
