Figures of out surface of an airplane model.

Computational figures of airplane surface are made to catch an airplane shape in the sence of sight. The airplane surface is described with a large number of quadrangles which are based on section lines of the airplane. In one concrete example, the section lines of an airplane model are measured. This airplane model is composed of a body, a wing, a tail unit and two jet engine nacelles. Several figures of the airplane model in various point of vision are drawn by using the law of perspective. These figures give us clear information of the Shape of the airplane model.
