PROBLEM TO BE SOLVED: To provide a three dimensional simulator equipment and an information storage medium capable of suppressing increase in operation volume. SOLUTION: This device includes a map information storage part 130 storing information on X- and Y-coordinates of Y-coordinate operation map formed as a combination of plural polygons for representing a boundary of a three- dimensional object in Y-coordinate direction, a plane coefficient storage part 140 storing coefficients of equation of a plane including each polygon in relation to the polygon for every polygon of the Y-coordinate operation map, a polygon selection part 110 selecting a corresponding polygon based on the information stored in X- and Z-coordinates of the aforesaid mobile body and the map information storage means, and a Y-coordinate calculation part 120 for reading the equation of the plane including the polygon based on the selected polygon and calculating the Y-coordinate of a corresponding point on the Y-coordinate calculation map based on the coefficients of the equation of the plane and the X- and Y-coordinates of the mobile body. |
