Abstract:

In 3D computer graphics, especially entertainments, game, CAD, 3D graphic design, virtual reality and simulation, the stereography is used to augment the sense of presence or to increase three-dimensional effects. The stereography is one of methods to represent artificial image in three-dimension. But all conventional three-dimensional stereographic image generation methods require the amount of computation, which is twice the amount for generating non-stereo image. This results in considerable restrictions in use of stereographic images in three-dimensional real-time rendering. This paper has been made from the observation of the above problem. The objective of this paper is to provide a method for generating a stereographic image using the Z-buffer, where two planar images required for generation of the stereographic image are created through generation of one image and simple additional tasks which are based on the created two-dimensional image, color information, and depth information stored in the Z-buffer. Compared to the conventional three-dimensional stereographic image generation method, which requires twice the amount of computer calculation time of the non-stereo image generation method, the present method can readily and rapidly generate the stereographic image through the simple algorithm without doubling the calculation load of the computer.
