The authers describe the algorithms for the half toned presentation of objects projected by a parallel light, and show the usefulness of the algorithms by some examples. The input data are represented by a set of the convex polyhedra constructing a object The algorithms are as follows. The light source is assumed the first observation point..The back faces to the light source are shading planes. Then wheter the contour lines on the projection plane intersect or not is decided. The intersecting area are shadows on to thefaces of a convex polyhedron hidden by another. The observers observation point is treated the second observation point.Then the relation of intersection of each polyhedron on the projection plane is decided.The last step is scanning to make the figure on the projection plane like the scanning of television.
