Abstract

A three-dimensional shape model indicating a first part is constructed and a three-dimensional shape that works as a transparent screen is disposed thereon continuously. A sight line direction is set and the three-dimensional shape model is displayed after rotated in accordance with the set sight line direction. A first two-dimensional image is constructed in accordance with the sight line direction, and a second two-dimensional image is constructed. The first two-dimensional image and the second two-dimensional image are combined with each other so as to construct a combined two-dimensional image. The combined two-dimensional image is assigned so that the part thereof corresponding to the first two-dimensional image agrees with the three-dimensional shape model, and the combined two-dimensional image is displayed visually.

Claims
