<p>PROBLEM TO BE SOLVED: To more appropriately express the contour line of a model.SOLUTION: A model formation method for, when plotting a first model configured of a plurality of polygons, forming a second model for expressing the contour line of the first model such that it is plotted so as to be overlapped with the first model includes: a first step (SP10) of acquiring extrusion vectors whose directions are different from those of normal vectors set in at least partial vertexes among the vertexes of the plurality of polygons; and a second step (SP12) of forming the second model on the basis of at least the first model and the extrusion vectors.</p> |
