Abstract:
1. A polygon rendering device comprising: a polygon division section for dividing, based on polygon data which specifies a polygon to be rendered, the polygon into a plurality of partial polygons such that at least one of the plurality of partial polygons has formed therein, from vertices thereof, a plurality of triangles which respectively share a vertex of the polygon; and a partial polygon rendering section for performing a rendering process and, without requiring, further division of any of the plurality of partial polygons, generating partial image data which represents an image of the at least one partial polygon from partial polygon data, wherein a plurality of partial image data represents an image of the polygon when combined, the polygon data includes n sets of vertex coordinates P said polygon division section generates the partial polygon data specifying at least the partial polygon formed by the reference vertex Pb, and the vertexes Pc, P(c+1), and P(c+2).
