Game apparatus, storage medium and computer program

Abstract

A game apparatus, a storage medium and a computer program, capable of reducing all processing of generating an image of a predetermined object in a virtual three-dimensional space without providing a substitute model for the predetermined object in the virtual three-dimensional space. The game apparatus comprises: an arrangement position setting section ( 212 ) for setting an arrangement expected position ( 20 a ) of a predetermined object in a virtual three-dimensional space; an image generation section ( 250 ) for generating a two-dimensional space image viewed from a virtual camera ( 10 ), based on the virtual three-dimensional space including the arrangement expected position; an image insertion section ( 254 ) for inserting a two-dimensional object image ( 20 ) expressing the predetermined object into a position corresponding to the arrangement expected position, of the two-dimensional space image; and an execution section for executing a predetermined game by displaying the two-dimensional space image including the two-dimensional object image.

What is claimed is:  
     
         1 . A game apparatus comprising: 
 an arrangement position setting section for setting an arrangement expected position of a predetermined object in a virtual three-dimensional space;    an image generation section for generating a two-dimensional space image viewed from a virtual camera, based on the virtual three-dimensional space including the arrangement expected position;    an image insertion section for inserting a two-dimensional object image expressing the predetermined object into a position corresponding to the arrangement expected position, of the two-dimensional space image; and    an execution section for executing a predetermined game by displaying the two-dimensional space image including the two-dimensional object image.    
     
     
         2 . A game apparatus as claimed in    claim 1   , 
 wherein the image insertion section changes a size of the two-dimensional object image to be inserted into the position of the two-dimensional space image, according to a distance from the virtual camera to the arrangement expected position in the virtual three-dimensional space.    
     
     
         3 . A game apparatus as claimed in    claim 1   , 
 wherein the image insertion section changes a color of the two-dimensional object image to be inserted into the position of the two-dimensional space image, on the basis of a predetermined attribute at the arrangement expected position in the virtual three-dimensional space.    
     
     
         4 . A game apparatus as claimed in    claim 3   , 
 wherein the predetermined attribute is an information on a light source or a fog.    
     
     
         5 . A storage medium having a computer-executable program recorded thereon, wherein the program comprises: 
 a program code of setting an arrangement expected position of a predetermined object in a virtual three-dimensional space;    a program code of generating a two-dimensional space image viewed from a virtual camera, based on the virtual three-dimensional space including the arrangement expected position;    a program code of inserting a two-dimensional object image expressing the predetermined object into a position corresponding to the arrangement expected position, of the two-dimensional space image; and    a program code of executing a predetermined game by displaying the two-dimensional space image including the two-dimensional object image.    
     
     
         6 . A storage medium having a computer-executable program recorded thereon, as claimed in    claim 5   , wherein the program further comprises: 
 a program code of changing a size of the two-dimensional object image to be inserted into the position of the two-dimensional space image, according to a distance from the virtual camera to the arrangement expected position in the virtual three-dimensional space.    
     
     
         7 . A storage medium having a computer-executable program recorded thereon, as claimed in    claim 5   , wherein the program further comprises: 
 a program code of changing a color of the two-dimensional object image to be inserted into the position of the two-dimensional space image, on the basis of a predetermined attribute at the arrangement expected position in the virtual three-dimensional space.    
     
     
         8 . A storage medium having a computer-executable program recorded thereon, as claimed in    claim 5   , wherein the program further comprises: 
 a program code of changing a color of the two-dimensional object image to be inserted into the position of the two-dimensional space image, on the basis of an information on a light source or a fog at the arrangement expected position in the virtual three-dimensional space.    
     
     
         9 . A computer program comprising program code means for performing the steps of: 
 setting an arrangement expected position of a predetermined object in a virtual three-dimensional space;    generating a two-dimensional space image viewed from a virtual camera, based on the virtual three-dimensional space including the arrangement expected position;    inserting a two-dimensional object image expressing the predetermined object into a position corresponding to the arrangement expected position, of the two-dimensional space image; and    executing a predetermined game by displaying the two-dimensional space image including the two-dimensional object image.    
     
     
         10 . A computer program as claimed in    claim 9   , further comprising program code means for performing the step of: changing a size of the two-dimensional object image to be inserted into the position of the two-dimensional space image, according to a distance from the virtual camera to the arrangement expected position in the virtual three-dimensional space.  
     
     
         11 . A computer program as claimed in    claim 9   , further comprising program code means for performing the step of: changing a color of the two-dimensional object image to be inserted into the position of the two-dimensional space image, on the basis of a predetermined attribute at the arrangement expected position in the virtual three-dimensional space.  
     
     
         12 . A computer program as claimed in    claim 9   , further comprising program code means for performing the step of: changing a color of the two-dimensional object image to be inserted into the position of the two-dimensional space image, on the basis of an information on a light source or a fog at the arrangement expected position in the virtual three-dimensional space.
