A form analyzing unit (4) receives 2-D outline data stored in an outline data storing unit (3) via an outline data obtaining unit (2), 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 (5) divides an area surrounded by the two outlines into convex polygons. A side generating unit (6) 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.
