  • Game image display method and game device
    Patent number: 6050896
    Abstract: A game image display method displays display objects in a virtual three dimensional space on a display screen. A three dimensional space coordinate system 200 fixed to a reference plane 200, and a three dimensional view point coordinate system 300 to follow a movement of a view point 500, and a two dimensional projection coordinate system 400 defined in relationship with the view point coordinate system 300 are set. Display objects 202-208 belonging to the space coordinate system 200, and display objects 302-304 belonging to the view point coordinate system 300 are projected on the projection coordinate system 400 to display the display objects. A two dimensional judgement coordinate system 350 corresponding to the projection coordinate system 400 is set in the view point coordinate system 300 to judge a collision between the display objects 202-208, 302-304, based on positions of the display objects 202-208, 302-304 projected on the judgement coordinate system 350.
