To provide a new program and an apparatus for three-dimensional image processing, capable of easily recognizing a three-dimensional virtual space.
A game apparatus 12 includes a CPU (40), and the CPU (40) executes three-dimensional image processing. When a cursor (106) on a display screen (100) is moved according to a user instruction, a gazed point is moved accordingly. In this case, a viewed volume (cone 200) is deformed so that the surface of the gazed point is maintained in an original position. Thus, in the display screen (100), the gazed point overlaps with a disappearance point (110). As a result, because of the overlap of the gazed point with the disappearance point, a front in the three-dimensional virtual space also becomes a front in the two-dimensional display screen, and it is possible to display a display screen on which the three-dimensional virtual space can easily be recognized.
