Curve::Spline class reference
[Core module]

This class is a member of the Curve namespace.

This class uses a 1d discrete data set to define a rotationally symmetric sagitta/gradient curve. Several data interpolations algorithm are available allowing use of Smooth Cubic spline interpolation with or without prescribed derivative/gradient data.

See also Data::DiscreteSet class.

Spline()

Create an empty spline curve with no defined point

~Spline()

No documentation available

virtual double derivative(double r) const

This virtual function overrides the derivative virtual function defined in the Rotational base abstract class.

Documentation inherited from base class:

Get curve derivative at specified distance from origin.

• r: distance from curve origin (0, 0)

void fit(const Rotational &c, double radius, unsigned int points)

Clear all points and fit to an other rotationally symmetric curve.

• c: Curve to fit
• radius: Maximum radius where curve is defined
• points: Number of sample points

const Data::DiscreteSet & get_data() const

Get sagitta/derivative data container

Data::DiscreteSet & get_data()

get sagitta/derivative data container

virtual double sagitta(double r) const

This virtual function implements the sagitta pure function declared in the Rotational base abstract class.

Documentation inherited from base class:

Get curve sagitta at specified distance from origin.

• r: distance from curve origin (0, 0)
