2148121 9410633 PCTABS00032 A rasterizer for generating pixel values for a pattern generation apparatus (503). The pixel value drives the printing mechanism (104) of the pattern generation apparatus. The rasterizer receives a file defining the pattern to be printed, fractures the pattern into sub frames, rasterizes each sub frame and then coordinates the provision of the shaded pixel values to the pattern generation apparatus. The rasterizer of the present invention is comprised primarily of a host processing means (501) for fracturing and translating the file into one or more subframes of pixels; geometry engines (505-508) for rasterizing each sub frame; beam board (512-513) for providing the pixel shading values to a pattern generation system; a serial bus for coupling the host processor means for geometry engines and beam boards and a pixel bus (514) for coupling each of the geometry engines to each of the beam boards.
