Recently, most of CG (computer graphics) have been changing from methods of vector scan graphics which are represented with lines, to methods of luster scan graphics with surfaces. The latter methods represent objects as being in the state of natural hue, therefore we need a high resolutional full-colored CRT and computer in order to display natural pictures. They are composed of, for example, a CRT, a large scale flame buffer where millions of colors are displayed, algorithm and processing of hardwares. So lots of beautiful pictures are published, which are drawn with specific machines and super computers. On the other hand, it can be said in using a micro computer that (1) the executing CG consumes much time, (2) the pixels are coarser to display CG, and (3) the number of colors is fewer than that in the above methods. We, however, can get quite beautiful pictures if we spend more time and efforts.<BR>In this study, we tried successfully to use the specified Z-buffer method that is one of the luster scan graphics methods. In addition, special semi-transparent and shadowing techniques are introduced to display more beautiful are natural images as its advanced applications with the low priced hardwares.
