Abstract
An image processing method and apparatus are described for polygon rendering in two dimensional screen space, where the rendering includes mapping of texels from a texture map onto pixels within the polygon. The texture map (18) holds fewer texels than would be required to render a full screen of pixels, or even a large polygon, and the rendering process is carried out in a sequence of rendering windows overlying successive areas of a polygon, with the texture memory (18) being refreshed from mass storage (12) as required between windows. Storage (20) is provided for calculated polygon edge data to enable continuous edges to be maintained over two or more rendering windows to avoid discontinuity effects.
