SPLINE INTERPOLATION SYSTEM.

摘要

A linear differential vector is determined from a predetermined number of points including a start point (P1) and a cubic equation between the start point (P1). A next point (P2) is determined from the coordinates value of predetermined points including the start point (P1) and the end condition of the start point (P1). Then, a spline curve between the start point (P1) and the next point (P2) continuing from the former is determined. Next, a spline curve between points P2 and P3 is determined by adding the linear differential vector at a new point in place of the start point (P1) and (P2).
