<p>PURPOSE:To attain the input of the 3-dimensional space coordinates by using one of both graphic input devices for the input of the Z axis coordinates. CONSTITUTION:A Z coordinate data bus is provided in addition to the x/y coordinate bus and a switch part 4 performs the switch of connection between those data buses and a graphic input part 5. In such a constitution, a control part 1 interprets a program stored in a program store part 2 and switches the Z coordinates supplied from the part 5 to the Z coordinate data bus by the function of the part 4 and according to said interpreted program. Thus a pattern displayed by the Z coordinates can be displayed at a display part 3. As a result, the simultaneous input is possible with (x), (y) and (z) coordinates together with use of a conventional graphic input device. This facilitates the easy input of the 3-dimensional coordinates.</p> |
