Spline type Properties and use
C spline
P1 to P7: specified coordinates
C spline (cubic spline)
P5
P7
P6
P4
P3
P2
P1
Properties:
Passes exactly 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 com‐
plete curved characteristic.
Application:
The C spline can be well used when the intermediate points lie on a curve defined
analytically (circle, parabola, hyperbola).
