Abstract
A graphics plotting apparatus has a decision unit for determining whether or not a polygon is smaller than a predetermined size, for example, the size of a pixel on a display screen or the size of a pixel on a texture pattern according to data of the vertexes of the polygon, a divider for dividing the polygon into small polygons if the polygon is not smaller than the predetermined size, and a plotting unit for plotting pixels corresponding to the polygon if the polygon is smaller than the predetermined size. This apparatus is capable of plotting perspective three-dimensional graphics with smooth shading and texture mapping at a high speed in real time.
