Curve::Grid class reference
[Core module]

This class is a member of the Curve namespace.

This class use the Data::Grid 2d data set container to define a 3d non-symmetric curve. Several data interpolation algorithms are available allowing use of Data::Bicubic spline interpolation with or without prescribed derivative/gradient data. .

The Spline curve model is preferred when dealing with rotationally symmetric curves.

See also Data::Grid class.

Grid(unsigned int n, double radius)

Creates a grid curve with n*n sample points defined over the given radius.

~Grid()

No documentation available

virtual void derivative(const Math::Vector2 &xy, Math::Vector2 &dxdy) const

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

Documentation inherited from base class:

Get curve x and y derivative (gradient) at specified point

void fit(const Base &c)

Set grid values to best fit an other curve. Gradient data will be extracted only if the interpolation have been set to Data::BicubicDeriv previously

const Data::Grid & get_data() const

Get embedded sagitta/gradient data container

Data::Grid & get_data()

Get embedded sagitta/gradient data container

virtual double sagitta(const Math::Vector2 &xy) const

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