Summary:To perform three-dimensional graphics processes by reducing the number of polygons to be processed, a storage unit ( 202 ) of an image processor ( 201 ) stores each of a plurality of polygons making up the surfaces of an object placed in a virtual three-dimensional space, in association with any of the surfaces of an approximate polyhedron which approximates the shape of the object, a determination unit ( 203 ) determines whether or not each of the surfaces of the stored approximate polyhedron can be seen in a case where the virtual three-dimensional space is observed along a predetermined sight line direction from a predetermined viewpoint, and a generation unit ( 204 ) generates an image, as observed along the predetermined direction from the predetermined viewpoint, of polygons, among the plurality of polygons stored in association, that are determined at a determining step as can been seen.
