ABSTRACT:
A form analyzing unit receives 2-D outline data stored in an outline data storing unit via an outline data obtaining unit, and judges from the received 2-D outline data whether an outline of a character includes an outline of a hole formed in the character. If so, a top/bottom dividing unit divides an area surrounded by the two outlines into convex polygons. A side generating unit moves each divided structure element in a z-axis direction to generate a side plane of the 3-D character, and generates 3-D data for the character.
