ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a a game system for displaying an image of an object moving in a virtual three-dimensional space.
2. Description of the Related Art
Recently, a game system which performs three-dimensional processing for a game picture has become common. For example, such as a shooting game, a game with a full of presence can be provided by displaying a three-dimensional situation in which an encountered opponent character is attacked.
In such a game system, a view point position and an observation paint, as standards for a display range, are settled in accordance with the situation as adz display object for a character or a various kind of constitution arranged at a predetermined coordinate position respectively on a game field settled in a virtual three-dimensional space.
Thus, a player can operate the character while watching a picture as if captured by a virtual camera which moves around freely in a three-dimensional game field.
However, for example such as in a shooting game, a character as an operation object generally moves very rapidly. Furthermore, the character changes its position intensely at a battle scene against an opponent character. Therefore, a problem which makes the player uncomfortable occurs, because a display picture in the three-dimensional space turns around rapidly when the player watches a specific observation point while following the movement of the character as an operation object by the above mentioned virtual camera to enhance the reality of the game.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a game system capable of solving the above mentioned problem. The game system is capable for displaying a game picture which makes the player feel presence and does not give the player an uncomfortable feeling when an operation object moving freely on the game field in the three-dimensional space is displayed.
Now, the present invention will be described.
According to the first embodiment of this invention, there is provided a game system arranging an object in a virtual three-dimensional space and displaying a visual field image on a game screen viewing the object from a predetermined view point position. In the game system, a plurality of view point positions are arranged in the virtual three-dimensional space, the view point position is selectively switched in accordance with a state of the object, and a visual field image is displayed on a game screen viewing the object from view point positions moving from one position to another when the view point position is switched.
According to another aspect of the first embodiment of this invention, there is provided a computer readable recording medium including a program for allowing a computer, included in a game system arranging an object in a virtual game space and displaying a visual field image on a game screen viewing an object from a predetermined view point position, to function so as to switch the view point position selectively in accordance with a state of the object by setting a plurality of view point positions in the virtual three-dimensional space, and to display the visual field image on the game screen viewing the object from view point positions moving from one position to another when the view point position is switched.
According to another aspect of the first embodiment of this invention, there is provided an image displaying method arranging an object in a virtual three-dimensional space and displaying a visual field image on a game screen viewing the object from a predetermined view point position. A plurality of view point positions are set or determined in the virtual three-dimensional space, the view point position is selectively switched in accordance with a state of the object, and a visual field image viewing the object from view point positions moving from one position to another is displayed on the screen.
According to these aspects of the first embodiment of the invention, an object in the virtual three-dimensional space is displayed on the game screen and the view point position is switched one after another in accordance with the state change of the object position. The view point position moves smoothly while displaying the object when the position is switched. Accordingly, the player can watch a picture from the most appropriate position in accordance with the game progress. Further, the player does not feel uncomfortable, resulting in a comfortable three-dimensional game with full of presence.
According to the second embodiment of this invention, there is provided a game system displaying an image on the game screen captured by a virtual camera from a predetermined view point position to an object moving in a virtual three-dimensional space in accordance with a player's operation, wherein the game system comprises a view point position setting device for setting a first view point position from which a predetermined observation point is viewed while following a movement of an operation object, and a second view point position from which the operation object is viewed in a predetermined fixed direction, and a virtual camera setting device for arranging the virtual camera by switching alternatively the first view point position to the second view point position corresponding to a state of the operation object and for moving the virtual camera along a virtual line connecting the first view point position with the second view point position while keeping a state of capturing the operation object when the view point position is switched.
According to another aspect of the second embodiment of this invention, there is provided a computer readable storage medium including a program for allowing a computer constituting a game system, the game system displaying a picture captured by a virtual camera from a predetermined view point position to an object moving in accordance with a player's operation in a virtual three-dimensional space, to function as, a view point position setting device for setting a first view point position to view a predetermined observation point following a movement of an operation object and a second view point position to fixedly view the operation object in a predetermined direction, and a virtual camera setting device for arranging the virtual camera by switching the first view point position alternatively to the second view point position corresponding to a state of the operation object, and for moving the virtual camera along a virtual line connecting the first view point position to the second view point position while keeping a state of capturing the operation object when the view point position is switched.
According to another aspect of the second embodiment of this invention, there is provided an image displaying method displaying a visual field image viewed from a predetermined view point position by a virtual camera toward an object moving in accordance with a player's operation in a virtual three-dimensional space, comprising, a view point position setting device for setting a first view point position for viewing a predetermined observation point by following a movement of an operation object, and a second view point position for fixedly viewing the operation object in a predetermined direction, and a virtual camera setting device for arranging the virtual camera by alternatively switching the first view point position to the second view point position in accordance with a state of the operation object, and moving the virtual camera along a line connecting the first view point position with the second view point position while keeping a state of capturing the operation object when the view point position is switched.
According to these aspects of the second embodiment of the invention, if the player operates the object so as to move it in the three-dimensional space during watching the game screen, the virtual camera is shifted between the first and the second view point position as occasion demands in accordance wi
