Abstract:
A method of generating graphic images on a display device of a computer system, comprising the steps of:dividing the viewable area of the display device into a plurality of tiles;assigning each of the tiles to a respective one of a plurality of rendering processes;rendering a frame on the display device using the respective rendering processes;adjusting the sizes of at least two of the tiles in response to said rendering step, andsmoothing at least two of the adjusted tile sizes, by calculating a smooth tile size aavg according to the formula:aavg=[w(0)*a(j)]+[w(1)*a(j-1)]+[w(2)*a(j-2)]+ . . . +[w(M)*a(j-M)]where a(j) is the size of a tile for the j-th frame rendered, M is an integer less than j, and w(i) is a weighing factor subject to the further formulaw(0)+w(1)+w(2)+ . . . +w(M)=1.
