PURPOSE: A morphing method of a descriptive geometry using a direction map is provided to extract direction maps from different descriptive geometries, and to apply a merge operation to the extracted direction maps, then to generate a polygon through a direction map reversed function, thereby smoothly morphing a specific descriptive geometry into different geometries. CONSTITUTION: By selecting a scaling and speed controlling method, a system is initialized(S301,S303). A control geometry is inputted(S305), and direction maps are extracted(S307). The extracted direction maps are merged together(S309). A trimming process for a concave feature shape is carried out(S311). Size of group units is controlled(S313). A polygon is created by using the merged direction maps(S315). In order to continuously generate a morphing intermediate geometry, a scaling factor value is changed from the fourth step, and the above procedure is repeated(S317).
