3d game display system, display method, and display program

A 3D game display method for displaying the progress of a game program in a two-dimensional screen with objects arranged in a virtual 3D space, the display method comprising:

• constructing the 3D space virtually, and controlling the position coordinates of the objects;
• displaying the 3D space two-dimensionally in the window in accordance with the field-of-view range on the basis of the type, area and shape of the window in the two-dimensional screen by the use of a 2D configuration unit, and controlling a graphic user interface which is arranged in the window for use in displaying information about the game and inputting operation to the game by the use of a user interface control unit;
• and
• receiving operation of the graphic user interface through an input interface, and changing the window in area or shape by the use of an expansion/contraction control unit on the basis of the operation input through the input interface,
• wherein the graphic user interface is displayed on the basis of the position and scale determined in accordance with the distance in relative coordinates from the base point which is unique to the window, and
• the expansion/contraction control unit calculates the position of the base point and the scale of the relative coordinates in accordance with the shape of the window.

A 3D game display program for displaying the progress of a game program in a two-dimensional screen with objects arranged in a virtual 3D space, the display program causing a computer to perform

• a step for virtually constructing the 3D space, and controlling the position coordinates of the objects;
• a step for two-dimensionally displaying the 3D space in the window in accordance with the field-of-view range on the basis of the type, area and shape of the window in the two-dimensional screen by the use of a 2D configuration unit, and controlling a graphic user interface which is arranged in the window for use in displaying information about the game and inputting operation to the game by the use of a user interface control unit;
• and
• a step for receiving operation of the graphic user interface through an input interface, and changing the window in area or shape by the use of an expansion/contraction control unit on the basis of the operation input through the input interface,
• wherein, in the step for two-dimensionally displaying the 3D space, the graphic user interface is displayed on the basis of the position and scale determined in accordance with the distance and angle relative to a base point in coordinates which is unique to the window, and
• in the step for receiving operation of the graphic user interface, the expansion/contraction control unit calculates the position coordinates of the base point in accordance with the shape of the window.
