<p><P>PROBLEM TO BE SOLVED: To conduct processing so that an object included in a right visual field area for generating a right visual field image may not be different from an object included in a left visual field area for a left visual field image to interactively operate a sight line without restricting the contents of expression about an object to be displayed when stereoscopic image data of double-eye parallax system are generated by a three-dimensional figure drawing method using computer graphics. <P>SOLUTION: When coordinate conversion is made by a geometry computation means 11 from object coordinates to displaying coordinates for a right visual field image and for a left visual field image, a common area clipping determination part 114a defines a third area 23 which is included both in a right visual field area and in a left visual field area, determines whether an object (a polygon) to be displayed is included in the third area 23, and displays only the object completely included in the third area 23. When only a part of an object to be displayed is included in the third area 23, only the included part is cut, hauled out and then displayed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
