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. The game image display method can conduct image display suitable for 3D games which gives the 3D games suitable difficulty and makes display images thereof realistic to make the 3D games amusing.
