    Abstract: 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.

    Abstract: (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.

    Abstract: A method comprises A: dividing an original curved surface (S) into at most six curved-surface units by combinations of signs (+, 0, -) of the principal curvature (k1, k2) at points on the original curved surface (S), B: dividing a changed curved surface (S') into curved-surface units having the same boundaries in such a way as to correspond to the original curved surface (S), C: finding average normal vectors of the curved-surface units of the original and changed curved surfaces, D: finding the "warp" components and "twist" components of all the combinations of pairs of different curved-surface units of the original and changed curved surfaces, and E: finding the differences between the "warp" and "twist" components of the combinations of the original curved surface and those of the combinations of the changed curved surface. Thus the overall shapes and errors of the original and changed curved surfaces after forming such as CAD data are readily and objectively compared, and the overall shape of a free curved surface is evaluated without being influenced by local "wrinkles" and "cavities". The numerical calculation of this method is easy, and the method is hardly influenced by numerical error and measurement error and applicable even to parametric curved surface and point group.
