PURPOSE:To attain an accurate correction processing by adding newly a means which changes automatically an unnatural pattern produced by a CAD into a smooth pattern. CONSTITUTION:As a start point P1 has a preceding shift of zero, 0 is added to codes I and J, and + and 0 are added to a mesh P2 since the shift started from the direction I has an increase with no change given to the shift started from the direction J respectively. Then codes (+) and (+) are added to a mesh P3 since it has an increment from the P2 in both directions I and J. The codes of refracted points are scanned successively to the coupled segments to which such said codes are added to detect a point where the code changed to (-) from (+) and vice versa. This mesh point is defined as a smoothing start point. In such a way, an unnatural region (window W1) on a memory with the detected smoothing base point mesh (P8) defined as an original point. |
