Three-dimensional game of the display system, display method and a display program

The three-dimensional space 35 virtually configured, the 3D structure unit 23 for controlling the coordinate position of the object, the window control section 22 for controlling the window 31 to 33 displayed on the screen, the type of window, area and shape depending on the field of view based on, is arranged a three-dimensional space 35 to two-dimensionally display 2D configuration unit 27 and the window in 33 for the window, GUI control unit for controlling the GUI34 for the display and operation relating to the game comprises a 24, an input interface 15 for performing an operation on the window 31 to 33 and GUI 34, and a scaling control unit 25 for changing the area or shape of the window 31 to 34 based on the operation by the input interface 15. In this way 3D games, as well as enable the display of diversified game content by a plurality of multi-window, while maintaining the operability of the GUI, it is possible to keep the balance between the display and the GUI of the game content itself.
