PURPOSE:To hold relative positions of control points at the time of designing and control the contour line by a simple process with a small volume of data. CONSTITUTION:The dot numbers of the contour line are held in Ns and Ne (step 101), and the difference between the (x) coordinates of Ns and Ne is held in X and the difference between the (y) coordinates is held in Y (step 102). Then X(N) is regarded as the (x) coordinate of a dot N and Y(N) is regarded as the (y) coordinate of the dot N; and X'(N) is regarded as the (x) coordinate of the dot N after movement and Y'(N) is regarded as (y) coordinate of the dot N after the movement, and a point right after the starting point is set to N (step 104). Further, N'(N) and T'(N) are calculated until the point N reaches the end point Ns, and N is increased to N+1 and the calculation is repeated (step 105, 106, and 107). Consequently, points between the dots Ns and Ne are moved so that the initial relative positions are maintained. |
