摘要： V-CAD data is prepared by dividing external data 12 consisting of boundary data of an object into rectangular parallelepiped cells 13 having boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cells 13a positioned on the inner side of the object and boundary cells 13b including a boundary face, and a modeling unit quantity of a prototyping material 7 is changed in accordance with sizes of the internal cell 13a and the boundary cell 13b of a modeling portion. The prototyping material 7 is a resin, lumber powder, a low-fusing-point metal, metal powder, ceramics powder or a mixture of a binder and one of these materials, and its modeling unit quantity is set in such a manner that the modeling unit quantity is smaller than a capacity of a corresponding cell and does not protrude from the boundary plane of the cell. As a result, by using the V-CAD data, a program for rapid prototyping can be simplified, and a model production time can be greatly reduced.

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.

摘要： (A) The surface shape of an object (1) is measured by varying the position and/or direction of measurement, and a plurality of sets of partially measured data (2) including the common parts (2a) are acquired, (B) for all the partially measured data (2), the overlapped ranges (3a) of the adjacent common parts (2a) are determined within the measurement error ranges (3), (C) when there are no superposition ranges (3a), it is decided that a combination is not possible, and (D) when there are overlapped ranges (3a), the common parts of each set of partially measured data are combined within the ranges. Thus, combined data can be created at a high accuracy from a plurality of sets of partially measured data based on a small number of repeated calculations.

摘要： A coordinate system R is set in which P0 is a coordinate origin, P0P1 conforms to a first U axis to have a unit length, P0P2 conforms to a second V axis to have a unit length, and P0P1×P0P2 is a unit vector conforming to a third N axis. A transforming matrix M that transforms an ordinary coordinate system into the coordinate system R and the u-, v- and n-coordinate values of the both ends of the line segment are calculated. It is determined whether or not the line segment intersects with the triangle, on the basis of the u-, v- and n-coordinate values. The u-, and v-coordinate values of the intersection point are calculated. It is determined whether or not the intersection point is positioned inside the triangle, on the basis of the u-, and v-coordinate values of the intersection point.
