ABSTRACT:
A three dimensional parallax drawing system for use in three dimensional graphics or virtual reality is disclosed. The parallax drawing system includes a three dimensional address generator which generates the original X-axis, Y-axis and Z-axis addresses of an image, and an address correction circuit for producing a corrected X-axis address in response to the original X-axis and Z-axis address outputs from the address generator. Also included is an address selection circuit for selecting either the original X-axis address supplied from the three dimensional address generator or the corrected X-axis address from the address correction circuit as a resultant X-axis address in response to a stereo graphic mode request signal. A frame buffer address generator is provided for converting the resultant X-axis address received from the address selection means and the Y-axis address received from the three dimensional address generator into the frame buffer linear address. The X-axis parallax of human eyes relative to all points of an object can be converted into the X-axis addresses. Thus, once the 3-D image of the object is projected by separating the left and right eyes' views and reflecting the corrected X-axis addresses, a more vivid image having a better perspective of distance can be seen though the LCD shutters.
