4.2 Spline interpolation (ASPLINE, BSPLINE, CSPLINE, BAUTO, BNAT, BTAN, EAUTO, ENAT, ETAN, PW, SD,
Spline type
C spline
254
Properties and use
Features:
•
The passes precisely through the specified intermediate points along the
curve.
•
The curve characteristic is tangential with continuous curvature.
•
Frequently generates undesirable oscillations, especially at positions where
the gradient changes significantly.
•
The area of influence of changes to the intermediate points is global. This
means that if an intermediate point is changed then this influences the
complete curved characteristic.
Application:
The C spline can be well used if the intermediate points lie on a curve that can be
analytically calculated defined (circle, parabola, hyperbola).
