Abstract

An apparatus of the invention generates an image including a plurality of pixels by mapping a plurality of texture data onto a surface of an object. The apparatus includes: a geometrical transformation section for geometrically transforming a curved surface defined in a 3-dimensional space into a curved surface in a 2-dimensional screen space; a micro-polygon generating section for dividing the curved surface in the 2-dimensional screen space into a plurality of partial curved surfaces in accordance with the number of the plurality of texture data, and for generating a micro-polygon in accordance with each of the plurality of partial curved surfaces; an area contribution determining section for determining an area contribution of the micro-polygon to a pixel included in the image, based on a relative positional relationship between the micro-polygon and the pixel; a texture data acquiring section for acquiring texture data in accordance with the micro-polygon; and an intensity-value determining section for determining an intensity value of the pixel, based on the area contribution determined by the area contribution determining section and the texture data acquired by the texture data acquiring section.
