ABSTRACT:
In a two-dimensional image display device for a three-dimensional computer graphics model, adjacent display screen units are combined by a joint with a sensor. The relative positions or relative angles of the adjacent display screen units are obtained by a sensor, and the result is output to a projection adjusting unit. When a sensor value is changed, the projection adjusting unit changes a viewpoint description and projection plane description in a way that the relative position or relative angle of the display screen unit satisfies the value obtained by the sensor. If the description of a specific projection plane is changed, then the description of the other projection plane is changed to satisfy the sensor value. Based on the changed contents of the viewpoint description unit and the projection plane description unit, a two-dimensional image of the three-dimensional computer graphics model is generated and displayed on the display screen unit.
