摘要： In coloration of a shaped article composed of a curable resin, the addition operation can be reliably conducted and a reliable coloration effect can be obtained in both the single-color addition and in the multicolor addition. A liquid-phase, non-colored photo-curable resin is cured by irradiation with laser light and a lowermost layer 5n is formed. A liquid-phase, photo-curable resin is applied on the upper surface thereof and a colored layer 5n-1 comprising a cured non-colored region and a liquid-phase pool region is formed. A color ink is drop-wise added to the liquid-phase pool region. The pool region is irradiated with laser light and cured to the same hardness as that of the non-colored region. A block-like coating film having the prescribed thickness if formed from the surface coating film produced by the color ink covering the pool region. As a result, the formation of the next layer (colored layer 5n-2) on the upper surface of colored layer 5n-1 can be conducted without obstacles. Colored layer 5n-2 through colored layer 53 are formed by repeating this process, a colored layer 52 is formed on the upper surface of colored layer 53, and then the uppermost layer 51 is formed on the colored layer 52.

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.

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.

摘要： An original curved surface S is divided into up to six curved surface units by combinations of signs (+, 0, −) of a principal curvature (k1, k2) in each point on the curved surface. A distorted curved surface S′ is associated with the original curved surface S and divided into curved surface units having the same boundary. An average normal vector is obtained for each curved surface unit with respect to the original curved surface and the distorted curved surface. “A bent component” and “a twisted component” in all the combinations of pairs of different curved surface units are obtained with respect to the original curved surface and the distorted curved surface. A difference between “the bent component” and “the twisted component” in each combination in the original curved surface and “the bent component” and “the twisted component” in each identical combination in the distorted curved surface is calculated.
