Abstract:
A method for a three dimensional parallax drawing system having a 3-D address generator which generates an original X-axis address, a Y-axis address, and a Z-axis address of an image, the method comprising:generating a corrected X-axis address in response to the original X-axis address and the Z-axis address; selecting either the original X-axis address or the corrected X-axis address as a resultant X-axis address in response to a stereo graphic mode request signal; converting the resultant X-axis address and the Y-axis address into a frame buffer address; determining whether a Y-axis vertical line is one that is necessary to give a parallax on X-axis scan lines; if the Y-axis vertical line is one that is necessary to give a parallax on X-axis scan lines, determining a horizontal point for the vertical line by the following expression: mod (frame buffer address/horizontal resolution)+F(z) where F(z) is a correction amount, and the frame buffer address denotes a linear address that is converted from the resultant X-axis address and the Y-axis address according to the following equation: frame buffer address=(Y-axis pixel numbers*horizontal resolution)+last scan line pixel numbers where the horizontal resolution is the number of pixels in a scan line; and if the Y-axis vertical line is not one that is necessary to give a parallax on X-axis scan lines, determining a horizontal point for the vertical line by the following expression: mod (frame buffer address/horizontal resolution).
