摘要
To judge impacts with a three-dimensional model constituted by a plurality of polygons, rapidly and accurately. The vertex-coordinates of the partial models constituting the three-dimensional model are represented by central-coordinates being the average values of the maximum values and minimum values of respective coordinate components, an expansion factor for achieving prescribed values by multiplication by the differentials between the maximum values and minimum values of each coordinate component, and converted vertex-coordinates obtained by subtracting the central-coordinates from the respective vertex-coordinates and then multiplying by the expansion factor; the central-coordinates and the expansion factor being stored as floating-point values, and the converted vertex-coordinates being stored as integers (ST3). Moreover, a judgement subject partial model, being a partial model of the partial models constituting the three-dimensional model to which impact judgement is to be applied, is selected (ST1), and impact judgement is performed with respect to this judgement subject partial model (ST7-ST11).
