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).
