3D image processing program, 3D image processing apparatus, 3D image processing system, and 3D image processing method

摘要

A game apparatus functioning as a three-dimensional image processing apparatus includes a CPU. The CPU executes three-dimensional image processing. When a cursor on a display screen is moved according to an instruction from a user, a gazing point is also moved acceding thereto. At this time, a view volume (cone) is deformed such that a gazing point plane is maintained at an original position. Thus, the gazing point and a vanishing point are overlapped with each other on the display screen.
