s) to create a prototype of the mold. Next, a mold release agent is applied to the completed mold, and about two glass fiber sheets are stuck thereon, soaked with a polyester resin, and applied and cured to a uniform thickness. After curing, the original form of the mold is removed to complete the FRP mold for mass production. FIG. 24 is a diagram showing an original form of this mold and a mold for mass production. As shown in the figure, a prototype 1 of a mold of an upper body and a mold 2 for mass production of a rear part thereof are shown. The mass production mold for the upper body is composed of two molds, a front body part and a back body part. Similarly, the head, the upper limb, and the lower body are each configured from a plurality of types.

[0004] Mass production of mannequins is performed using the FRP mold for mass production. First, FRP is applied to the inside of each mold for mass production, and a plurality of molds are screwed to each part. FIG. 25 shows an upper body and a head mold in which FRP is applied to the inside and screwed.
In the figure, reference numerals 3 and 4 denote a head type and an upper body type, respectively, and the head includes three types of a right front part, a left front part, and a rear part. Thereafter, when the FRP applied to the inside of the mold for mass production is cured, the mold for mass production is removed, and the mannequin for each part is completed. FIG. 26 shows the completed virgin mannequin before coloring. In the figure, only the head 5 and the upper body 6 are shown, and both are fixed by screws.

Embodiments of the present invention will be described below with reference to the drawings. <First Embodiment> In the first embodiment, an example in which the present invention is applied to a method of manufacturing a mannequin will be described.

FIGS. 1 to 3 show display screens on a display when a completed mannequin is modeled using 3D software on a personal computer. 1 to 3 respectively show a front part of the mannequin, a left side part of the mannequin, and a top part of the mannequin. Note that the mannequin shown in FIGS. 1 to 3 is displayed in a wire frame, and the head and lower limbs are omitted. Also, as the 3D software used in this example, for example, LightWa
ve3D, Expression Shade, or the like is conceivable. FIG. 4 is a diagram illustrating an example of a mannequin modeling method using 3D software. As shown in the figure, for a mannequin composed of a plurality of polygons, for example, when there is a part to be bulged outward,
The vertex 10 of the polygon is pulled out in the direction in which it is desired to inflate. By doing so, a bulge can be provided at that portion. In the figure, one point of the polygon is extremely drawn out for easy understanding. Although not shown, if there is a part to be retracted, the vertices of the polygon of the part to be retracted may be retracted inward of the mannequin, contrary to the case where the part is to be inflated. By repeating such operations, modeling of the mannequin is performed. Therefore, modeling of a mannequin is performed on a personal computer in 3D.
Since it can be performed using software, there is no need for a specialized craftsman to work with clay using handicraft as in the related art, and the modeling work can proceed efficiently.

When the modeling of the mannequin is completed, the modeled mannequin is provided with a division surface at an arbitrary pitch.

In the subsequent processing, since only the outline of the division plane shown in the top view of the upper part of FIG. 7 is meaningful data, the 3D data of the upper part of the mannequin is converted to the upper surface of the upper part of FIG. The data is converted into 2D data composed only of the outlines of the plurality of divided surfaces shown in the figure. In the 2D data, as described above, the outlines of the divided surfaces remain jagged. Therefore, in order to smooth the jagged outlines of the divided surfaces, the outlines are smoothed using draw-based software. Note that as draw-based software, for example, Adobe's illust
