METHOD AND DEVICE FOR CONTROLLING 3 DIMENSION ON SCREEN

PURPOSE: A method and a device for controlling the 3-dimension on a screen are provided to input of 3-dimensional graphic image in real time in order to easily control the movement of view point and the manipulation of object in a 3-dimensional environment. CONSTITUTION: The method comprises steps of controlling the far and near of object on a screen by moving forward or backward output device in order to control the object representing on the screen of output device to the near or far distance(200), controlling the up/down rotational movement of object by rotating up/down the output device according to a virtual horizontal line crossing the center of object in order to control the rotational movement following to the virtual perpendicular line crossing the object center from a bottom to a top(220), and controlling the left/right movement of object by rotating left/right the output device to the virtual perpendicular line crossing the object center in order to control the rotational movement following to the virtual horizontal line crossing the object center from a left side to a right side(240).
