◆ IsTypeOf()

static vtkTypeBool vtkWarpTransform::IsTypeOf ( const char * type )

static

◆ IsA()

virtual vtkTypeBool vtkWarpTransform::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractTransform.

Reimplemented in vtkCylindricalTransform, vtkSphericalTransform, vtkThinPlateSplineTransform, vtkBSplineTransform, and vtkGridTransform.

◆ SafeDownCast()

static vtkWarpTransform * vtkWarpTransform::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkWarpTransform::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkAbstractTransform.

Reimplemented in vtkCylindricalTransform, vtkSphericalTransform, vtkThinPlateSplineTransform, vtkBSplineTransform, and vtkGridTransform.

◆ NewInstance()

vtkWarpTransform * vtkWarpTransform::NewInstance ( ) const

◆ PrintSelf()

void vtkWarpTransform::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkAbstractTransform.

Reimplemented in vtkBSplineTransform, and vtkGridTransform.

◆ Inverse()

void vtkWarpTransform::Inverse ( )

overridevirtual

Invert the transformation.

Warp transformations are usually inverted using an iterative technique such as Newton's method. The inverse transform is usually around five or six times as computationally expensive as the forward transform.

Implements vtkAbstractTransform.

◆ GetInverseFlag()

virtual int vtkWarpTransform::GetInverseFlag ( )

virtual

Get the inverse flag of the transformation.

This flag is set to zero when the transformation is first created, and is flipped each time Inverse() is called.

◆ SetInverseTolerance()

virtual void vtkWarpTransform::SetInverseTolerance ( double )

virtual

Set the tolerance for inverse transformation.

The default is 0.001.

◆ GetInverseTolerance()

virtual double vtkWarpTransform::GetInverseTolerance ( )

virtual

Set the tolerance for inverse transformation.

The default is 0.001.

◆ SetInverseIterations()

virtual void vtkWarpTransform::SetInverseIterations ( int )

virtual

Set the maximum number of iterations for the inverse transformation.

The default is 500, but usually only 2 to 5 iterations are used. The inversion method is fairly robust, and it should converge for nearly all smooth transformations that do not fold back on themselves.

◆ GetInverseIterations()

virtual int vtkWarpTransform::GetInverseIterations ( )

virtual

Set the maximum number of iterations for the inverse transformation.

The default is 500, but usually only 2 to 5 iterations are used. The inversion method is fairly robust, and it should converge for nearly all smooth transformations that do not fold back on themselves.

◆ InternalTransformPoint() [1/2]

		float	out[3]
	)

overridevirtual

This will calculate the transformation without calling Update.

Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

◆ InternalTransformPoint() [2/2]

void vtkWarpTransform::InternalTransformPoint	(	const double	in[3],
		double	out[3]
	)

overridevirtual

This will calculate the transformation without calling Update.

Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

◆ InternalTransformDerivative() [1/2]

void vtkWarpTransform::InternalTransformDerivative	(	const float	in[3],

	)

overridevirtual

This will calculate the transformation, as well as its derivative without calling Update.

Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

◆ InternalTransformDerivative() [2/2]

void vtkWarpTransform::InternalTransformDerivative	(	const double	in[3],
