<p>A graphics system in which processing speed can be improved by merely increasing the number of drawing mechanisms when an image containing a transparent object is generated. The graphics system comprises synthesizing means that includes a plurality of drawing mechanisms each comprising a geometric processor, a rendering processor and a frame memory for holding color, depth and weight information in a bit map form of a screen. The synthesizing means first compares the depth information from the color, depth and weight information of the same pixel position (the same address) read out from the frame memory of each drawing mechanism, multiplies the weight information by the color information from the figure on the front side, and generates a new pixel information, in this way, transparent objects can be merged.</p> |
