There is provided a method for texturing and shading a 3D computer graphic image on a plurality of shading engines. First, the image is subdivided into a plurality of tiles and each tile is subdivided into a plurality of micro tiles. An object list is allocated to each tile, the object list containing data defining objects visible in the tile. For one micro tile, it is determined which pixels in the micro tile are intersected by an object A in the object list and it is determined which pixels in the micro tile are intersected by at least one other object in the object list. In parallel with the determination step, pixel intersection data is outputted for an object B for which all intersection determinations for each of the micro tiles in a selected tile have been performed. The pixel intersection data is output to at least one of the plurality of shading engines. Then, those steps are repeated for each micro tile in the selected tile in which there are visible objects. The pixels corresponding to the pixel intersection data for the object B are textured and shaded with the at least one of the plurality of shading engines. Finally, the data derived by the texturing and shading is stored.
