Abstract:
A driving game machine wherein a player automobile is displayed by a display device in a three-dimensional depiction along with at least one general automobile on a three-dimensional road, the driving game machine comprising:three-dimensional data memory means for storing coordinate data of said three-dimensional road in a three-dimensional coordinate system;two-dimensional data memory means for storing coordinate data of a two-dimensional road corresponding to said three-dimensional road transformed to a two-dimensional coordinate system;player automobile control means for controlling said player automobile on said three-dimensional road in response to input by a player and for generating three-dimensional player automobile coordinate data representing a position of said player automobile on said three-dimensional road;a dimensional coordinate system transforming means for transforming coordinate data between said two-dimensional coordinate system and said three-dimensional coordinate system;said two-dimensional coordinate system having a first coordinate axis corresponding to a road length of said three-dimensional road and a travel distance of said player automobile on said three-dimensional road being represented in terms of a first coordinate corresponding to a position on said first coordinate axis;an image display processor for driving said display device to produce said three-dimensional depiction based on said coordinate data of said three-dimensional road in said three-dimensional coordinate system;a course coordinate system processor for controlling said dimensional coordinate system transforming means and said image display processor to produce said three-dimensional depiction; andsaid course coordinate system processor including a general automobile control means for controlling said at least one general automobile on said two-dimensional road and for generating two-dimensional general automobile coordinate data representing a position of said general automobile on said two-dimensional road.
