virtual const char* vtkWarpTransform::GetClassName (  )  [virtual]

static int vtkWarpTransform::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractTransform.

Reimplemented in vtkCylindricalTransform, vtkSphericalTransform, vtkGridTransform, and vtkThinPlateSplineTransform.

virtual int 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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractTransform.

Reimplemented in vtkCylindricalTransform, vtkSphericalTransform, vtkGridTransform, and vtkThinPlateSplineTransform.

static vtkWarpTransform* vtkWarpTransform::SafeDownCast ( vtkObject o  )  [static]

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

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 vtkCylindricalTransform, vtkSphericalTransform, vtkGridTransform, and vtkThinPlateSplineTransform.

void vtkWarpTransform::Inverse (  )  [virtual]

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.

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.

virtual void vtkWarpTransform::SetInverseTolerance ( double   )  [virtual]

Set the tolerance for inverse transformation. The default is 0.001.

virtual double vtkWarpTransform::GetInverseTolerance (  )  [virtual]

Set the tolerance for inverse transformation. The default is 0.001.

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.

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.

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

This will calculate the transformation without calling Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

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

This will calculate the transformation without calling Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

void vtkWarpTransform::InternalTransformDerivative ( const float  in[3],
float  out[3],
float  derivative[3][3] 
) [virtual]

This will calculate the transformation, as well as its derivative without calling Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

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

Implements vtkAbstractTransform.

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