Detailed Description

abstract interface for parametric functions

vtkParametricFunction is an abstract interface for functions defined by parametric mapping i.e. f(u,v,w)->(x,y,z) where u_min <= u < u_max, v_min <= v < v_max, w_min <= w < w_max. (For notational convenience, we will write f(u)->x and assume that u means (u,v,w) and x means (x,y,z).)

The interface contains the pure virtual function, Evaluate(), that generates a point and the derivatives at that point which are then used to construct the surface. A second pure virtual function, EvaluateScalar(), can be used to generate a scalar for the surface. Finally, the GetDimension() virtual function is used to differentiate 1D, 2D, and 3D parametric functions. Since this abstract class defines a pure virtual API, its subclasses must implement the pure virtual functions GetDimension(), Evaluate() and EvaluateScalar().

This class has also methods for defining a range of parametric values (u,v,w).

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

Reimplemented in vtkParametricHenneberg, vtkParametricKlein, vtkParametricKuen, vtkParametricMobius, vtkParametricPluckerConoid, vtkParametricPseudosphere, vtkParametricRandomHills, vtkParametricRoman, vtkParametricSpline, vtkParametricSuperEllipsoid, vtkParametricSuperToroid, and vtkParametricTorus.

◆ GetDimension()

virtual int vtkParametricFunction::GetDimension ( )
pure virtual

Return the dimension of parametric space.

Depending on the dimension, then the (u,v,w) parameters and associated information (e.g., derivates) have meaning. For example, if the dimension of the function is one, then u[0] and Duvw[0...2] have meaning. This is a pure virtual function that must be instantiated in a derived class.

Implemented in vtkParametricBohemianDome, vtkParametricBour, vtkParametricBoy, vtkParametricCatalanMinimal, vtkParametricConicSpiral, vtkParametricCrossCap, vtkParametricDini, vtkParametricEllipsoid, vtkParametricEnneper, vtkParametricFigure8Klein, vtkParametricHenneberg, vtkParametricKlein, vtkParametricKuen, vtkParametricMobius, vtkParametricPluckerConoid, vtkParametricPseudosphere, vtkParametricRandomHills, vtkParametricRoman, vtkParametricSpline, vtkParametricSuperEllipsoid, vtkParametricSuperToroid, and vtkParametricTorus.

◆ Evaluate()

virtual void vtkParametricFunction::Evaluate ( double  uvw[3],
double  Pt[3],
double  Duvw[9] 
)
pure virtual

Performs the mapping $f(uvw)->(Pt,Duvw)$f.

This is a pure virtual function that must be instantiated in a derived class.

uvw are the parameters, with u corresponding to uvw[0], v to uvw[1] and w to uvw[2] respectively. Pt is the returned Cartesian point, Duvw are the derivatives of this point with respect to u, v and w. Note that the first three values in Duvw are Du, the next three are Dv, and the final three are Dw. Du Dv Dw are the partial derivatives of the function at the point Pt with respect to u, v and w respectively.

Implemented in vtkParametricSpline, vtkParametricBohemianDome, vtkParametricBour, vtkParametricBoy, vtkParametricCatalanMinimal, vtkParametricConicSpiral, vtkParametricCrossCap, vtkParametricDini, vtkParametricEllipsoid, vtkParametricEnneper, vtkParametricFigure8Klein, vtkParametricHenneberg, vtkParametricKlein, vtkParametricKuen, vtkParametricMobius, vtkParametricPluckerConoid, vtkParametricPseudosphere, vtkParametricRandomHills, vtkParametricRoman, vtkParametricSuperEllipsoid, vtkParametricSuperToroid, and vtkParametricTorus.

◆ EvaluateScalar()

virtual double vtkParametricFunction::EvaluateScalar ( double  uvw[3],
double  Pt[3],
double  Duvw[9] 
)
pure virtual

Calculate a user defined scalar using one or all of uvw, Pt, Duvw.

This is a pure virtual function that must be instantiated in a derived class.

uvw are the parameters with Pt being the cartesian point, Duvw are the derivatives of this point with respect to u, v, and w. Pt, Duvw are obtained from Evaluate().

Implemented in vtkParametricSpline, vtkParametricBohemianDome, vtkParametricBour, vtkParametricBoy, vtkParametricCatalanMinimal, vtkParametricConicSpiral, vtkParametricCrossCap, vtkParametricDini, vtkParametricEllipsoid, vtkParametricEnneper, vtkParametricFigure8Klein, vtkParametricHenneberg, vtkParametricKlein, vtkParametricKuen, vtkParametricMobius, vtkParametricPluckerConoid, vtkParametricPseudosphere, vtkParametricRandomHills, vtkParametricRoman, vtkParametricSuperEllipsoid, vtkParametricSuperToroid, and vtkParametricTorus.

Set/Get the flag which determines whether derivatives are available from the parametric function (i.e., whether the Evaluate() method returns valid derivatives).

◆ GetDerivativesAvailable()

virtual vtkTypeBool vtkParametricFunction::GetDerivativesAvailable ( )
virtual

Set/Get the flag which determines whether derivatives are available from the parametric function (i.e., whether the Evaluate() method returns valid derivatives).

◆ DerivativesAvailableOn()

virtual void vtkParametricFunction::DerivativesAvailableOn ( )
virtual

Set/Get the flag which determines whether derivatives are available from the parametric function (i.e., whether the Evaluate() method returns valid derivatives).

◆ DerivativesAvailableOff()

virtual void vtkParametricFunction::DerivativesAvailableOff ( )
virtual

Set/Get the flag which determines whether derivatives are available from the parametric function (i.e., whether the Evaluate() method returns valid derivatives).
