Claim:
1. A slice data generator for generating slice data representing a cross section cut from a three-dimensional modeled object comprising: a changing unit for changing topology information of a polygon mesh so that a contour polyline is obtained indicating a contour line of a cut cross unit of the polygon mesh; a modifying unit for acquiring the contour polyline from the polygon mesh, the topology information of the polygon mesh having been changed by said changing unit, and modifying said contour polyline so that an inside which is a region inside said acquired contour polyline can be normally filled; and a setting unit for setting a luminance value for each of a plurality of first pixels constituting the slice data on the basis of a positional relationship between said contour polyline modified by said modifying unit and each first pixel, wherein said setting unit sets a first luminance value for each first pixel that is entirely inside said contour polyline, and sets a second luminance value smaller than said first luminance value for each first pixel that is entirely outside said contour polyline.
