Game device, method of processing and recording medium for the same
A game device models images of moving images such as motor-bikes or cars moving through a virtual space. The track along which a first such moving object moving through the virtual space is sampled at a prescribed interval in time in order to generate track data P 1 –P 6 , while transit points P 1 ′–P 6 ′ are set at prescribed intervals of distance along the track indicated by the track data. A second moving object is moved in such a manner as to pass through these transit points. Accordingly, a course is set that is commensurate with the player's skill level so that the degree of difficulty of the game is not diminished by the degree of experience of the player.
1. A game device wherein viewpoint images are generated whereby a virtual space is viewed from a stipulated viewpoint which moves together with a specific moving object, comprising:
means for determining stance whereby the stance of said moving object within the virtual space is determined;
means for determining a head position of a virtual driver on the basis of the stance of said specific moving object determined by said means for determining stance, relative position coordinates between the head of the virtual driver, which moves with said specific moving object, and said specific moving object itself are determined; and
means for controlling display whereby said viewpoint is set on position coordinates determined by said means for determining head position, and said viewpoint image is generated by approximating the direction of a specified coordinate axis of said viewpoint image viewed from said viewpoint to a preset vertical direction in said space, wherein the specified coordinate axis is the Y-axis of said viewpoint image, and wherein the Y-axis is always maintained parallel to a vertical axis of a world coordinate system, the Y-axis does not shift in the virtual space, and an image is displayed that represents a view perceived by an actual driver.
2. The game device of claim 1 , wherein the specific moving object is a bike and wherein the head position is made to correspond with an inclination of the bike and altered in a direction of one side of the bike.
3. A method for a game device wherein at least one viewpoint image is generated whereby a virtual space is viewed from a viewpoint which moves together with a specific moving object, the method comprising:
determining stance of said moving object within the virtual space;
determining a head position of a virtual driver on the basis of the stance of said specific moving object, wherein relative position coordinates between the head of the virtual driver, which moves with said specific moving object, and said specific moving object itself are determined; and
controlling display whereby said viewpoint is set on position coordinates, and said at least one viewpoint image is generated by approximating the direction of a specified coordinate axis of said at least one viewpoint image viewed from said viewpoint to a preset vertical direction in said space, wherein the specified coordinate axis is the Y-axis of said at least one viewpoint image, and wherein the Y-axis is always maintained parallel to a vertical axis of a world coordinate system, the Y-axis does not shift in the virtual space, and an image is displayed that represents a view perceived by an actual driver.
4. The method of claim 3 , wherein the specific moving object is a bike and wherein the head position is made to correspond with an inclination of the bike and altered in a direction of one side of the bike.
5. A computer-readable medium containing instructions for a method for a game device wherein at least one viewpoint image is generated whereby a virtual space is viewed from a viewpoint which moves together with a specific moving object, the method comprising:
determining stance of said moving object within the virtual space;
determining a head position of a virtual driver on the basis of the stance of said specific moving object, wherein relative position coordinates between the head of the virtual driver, which moves with said specific moving object, and said specific moving object itself are determined; and
controlling display whereby said viewpoint is set on position coordinates, and said at least one viewpoint image is generated by approximating the direction of a specified coordinate axis of said at least one viewpoint image viewed from said viewpoint to a preset vertical direction in said space, wherein the specified coordinate axis is the Y-axis of said at least one viewpoint image, and wherein the Y-axis is always maintained parallel to a vertical axis of a world coordinate system, the Y-axis does not shift in the virtual space, and an image is displayed that represents a view perceived by an actual driver.
6. The computer-readable medium of claim 5 , wherein the specific moving object is a bike and wherein the head position is made to correspond with an inclination of the bike and altered in a direction of one side of the bike.
