PURPOSE:To provide a graphic processor which can deal with the stereoscopic graphics and can carry out the geometric change processing of the stereoscopic graphics with high operability. CONSTITUTION:A graphic processor carries out the geometric change processing of the stereoscopic graphics shown on a display screen based on the coordinate position information pointed by a coordinate pointing device. Then the graphic processor is provided with ah acquiring part 13 which acquires the 1st coordinate position information on the stereoscopic graphic pointed by the coordinate pointing device, a specifying part 14 which specifies the stereoscopic graphic element information on the stereoscopic graphic pointed by the 1st coordinate position information, an acquiring part 15 which acquires the 2nd coordinate position information pointed by the coordinate pointing device, a calculating part 17 which calculates the changed graphic information on the stereoscopic graphic that received a geometric change processing request based on the 1st and 2nd coordinate position information and the stereoscopic graphic element information, and a display control part 12 which shows the changed stereoscopic graphic that received the geometric change processing request on a display screen based on the calculated graphic information.
