PURPOSE:To easily recognize and specify an optional position in a three- dimensional(3-D) space in a system for processing a 3-D graphic. CONSTITUTION:This 3-D coordinate value input system is provided with an input coordinate processing part 1 for inputting a 2-D coordinate value from an input device for determining a 3-D coordinate position, a 3-D coordinate conversion processing part 2 for converting the 2-D coordinate value into a 3-D coordinate value, a multi-view cursor display processing part 3 for displaying a cross hair cursor on each view window based upon the converted 3-D coordinate value, and a coordinate output processing part 4 for receiving a current 3-D coordinate value from the processing part 2 based upon a trigger input and determining the received value. |
