PURPOSE:To draw a three-dimensionally analyzed figure to be natural and easily analyzed by calculating only a part, where a line segment to be drawn is hidden on the side of an operator, with high resolution and executing a hidden-line processing. CONSTITUTION:A newly added high resolution drawing data generating means 9 generates the drawing data of the part, where the line segment is hidden, with two-dimensional coordinate data from a coordinate converting means 3 and data from a MAX buffer 6 as the inputs. The drawing data generated in this means 9 is impressed to a display means 8 corresponding to the output of a first comparator 5 and displayed while improving the resolution rather than internal picture elements concerning the part where the line segment is hidden in the line segment on the operator side. Thus, time required for display is not increased so much and the three-dimensionally analyzed picture can be drawn by the line segment without interruption. |
