Spline function interpolation smooth curve
no vote
Application background Spline function interpolation smooth curve, can realize the smooth curve of the discrete points, in the contour tracing to complete the available magnetic algorithm for smooth. For closed curves, the code should be improved. Key Technology Using the three spline function method to smooth the curve interpolation, the speed is very fast, the only drawback is that the closure of the line is not smooth, the need to improve the user to improve.
