Abstract
In this paper the authors propose new fast data generation method for the computer graphics which is effectively used in civil engineering field.The method is divided into three functions.The first function generates triangles which can cover any natural ground surface, the second function operatesto generate surface of artificial 3D body, and the last function defines whole triangles of these two kind of surface. Proposed method is based on the Delaunay Triangulation. The method can generate not only all counter lines but also triangles to show actua topography. A number of test problems show the efficiency of the proposed method.
