Curve::ConicBase class reference
[Core module]

This class is a member of the Curve namespace.

This abstract class contains pure virtuals.

This base class defines common properties of rotationally symmetric conic curves. These curves are all defined by a radius of curvature and deformation coefficient.

Fitting can be used to find best fit conic of an other rotationally symmetric curve either with fixed or free deformation parameter.

See also the full member list section for this class.

• virtual double derivative(double r) const = 0;
• double fit_roc(const Rotational &c, double radius, unsigned int count)

This pure virtual function shadows 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)

Adjust radius of curvature to best fit given curve. Deformation Won't be changed by this function. See Conic::fit() to adjust deformation too.

Parameters list:

• curve: Curve to fit
• radius: Maximum radius used to get sample points
• count: Number of sample points to use

get eccentricity

get Schwarzschild constant

This pure virtual function shadows the intersect virtual function defined in the Base base abstract class.

Documentation inherited from base class:

Get intersection point between curve and 3d ray. Return false if no intersection occurred

This pure virtual function shadows the sagitta pure virtual function defined 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)
