Abstract
This invention provides a three-dimensional (3D) simulator apparatus that is capable of forming a high-quality pseudo-3D image in real time, even when a large number of display objects crowd in close to a given viewpoint. An object image information storage section (212) stores image information for a plurality of types of objects with differing numbers of polygons (resolutions). A first setting unit (120) sets resolutions in such a manner that the resolution of a display object increases as the sequence number group to which the sequence number of the display object belongs gets closer to the viewpoint. A second setting unit (122) sets resolutions in such a manner that the resolution of a display object increases as the distance range in which the display object is positioned comes closer to the viewpoint. The setting made by the second setting unit (122) is modified by the setting result of the first setting unit (120).
