  • Image processing device, image processing method, game device, and craft simulator
    Patent number: 6731278
    Abstract: To achieve a more realistic and richer shifting field, such as water surface over which a jet-ski or other object travels, thereby heightening the interest and ambiance of the game. An image processing device for processing image data for moving an object such as a watercraft over a water surface in three-dimensional space. Comprises means for cyclically shifting the height at given positions of the water surface over time (CPU 101) and means for moving the watercraft while contacting the water (CPU 101). Determination of contact between watercraft and water surface, watercraft tilt correction, boat wake drawing processing, and the like are performed by the CPU 101.
