Abstract
A polygon rendering capability detecting part detects the rendering capability of the equipment used so as to calculate the total number of polygons Nap that can be allocated in one frame. A visual quality determining part determines an average area Sp represented by one polygon on a display screen as visual quality, and an optimum polygon number calculating part calculates the optimum number of polygons Np that can be allocated based on the size of a three-dimensional character projected on the display screen while maintaining the visual quality Sp constant. A polygon number adjusting part lowers the progressive polygon level of the three-dimensional character so that the number of polygons of the three-dimensional character is not less than the calculated optimum number of polygons and is the smallest number of polygons to which the number of polygons can be reduced. When the three-dimensional character moves and the Z value is changed, Np is updated so that Sp becomes constant.
