Detailed Description

a linear transform specified by two.

Date:

Revision:

1.10

Thanks:

Thanks to Tim Hutton and David G. Gobbi who developed this class. corresponding point sets

A vtkLandmarkTransform is defined by two sets of landmarks, the transform computed gives the best fit mapping one onto the other, in a least squares sense. The indices are taken to correspond, so point 1 in the first set will get mapped close to point 1 in the second set, etc. Call SetSourceLandmarks and SetTargetLandmarks to specify the two sets of landmarks, ensure they have the same number of points.

Warning:

Whenever you add, subtract, or set points you must call Modified() on the vtkPoints object, or the transformation might not update.

Member Function Documentation

vtkLandmarkTransform* vtkLandmarkTransform::New (    )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLinearTransform.

int vtkLandmarkTransform::IsTypeOf (  const char *    type )  [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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLinearTransform.

virtual int vtkLandmarkTransform::IsA (  const char *    type )  [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 vtkLinearTransform.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLinearTransform.

void vtkLandmarkTransform::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 vtkLinearTransform.

void vtkLandmarkTransform::SetSourceLandmarks (  vtkPoints *    points )

Specify the source and target landmark sets. The two sets must have the same number of points. If you add or change points in these objects, you must call Modified() on them or the transformation might not update.

void vtkLandmarkTransform::SetTargetLandmarks (  vtkPoints *    points )

virtual vtkPoints* vtkLandmarkTransform::GetSourceLandmarks (    )  [virtual]

virtual vtkPoints* vtkLandmarkTransform::GetTargetLandmarks (    )  [virtual]

virtual void vtkLandmarkTransform::SetMode (  int    )  [virtual]

Set the number of degrees of freedom to constrain the solution to. Rigidbody: rotation and translation only. Similarity: rotation, translation and isotropic scaling. The default is similarity.

void vtkLandmarkTransform::SetModeToRigidBody (    )  [inline]

Definition at line 93 of file vtkLandmarkTransform.h.

void vtkLandmarkTransform::SetModeToSimilarity (    )  [inline]

Definition at line 94 of file vtkLandmarkTransform.h.

virtual int vtkLandmarkTransform::GetMode (    )  [virtual]

const char * vtkLandmarkTransform::GetModeAsString (    )  [inline]

Definition at line 127 of file vtkLandmarkTransform.h.

void vtkLandmarkTransform::Inverse (    )  [virtual]

Invert the transformation. This is done by switching the source and target landmarks. Reimplemented from vtkAbstractTransform.

unsigned long vtkLandmarkTransform::GetMTime (    )  [virtual]

Get the MTime. Reimplemented from vtkAbstractTransform.

vtkAbstractTransform* vtkLandmarkTransform::MakeTransform (    )  [virtual]

Make another transform of the same type. Reimplemented from vtkAbstractTransform.

void vtkLandmarkTransform::operator= (  const vtkLandmarkTransform &    )  [inline, protected]

Definition at line 112 of file vtkLandmarkTransform.h.

void vtkLandmarkTransform::InternalUpdate (    )  [protected, virtual]

Perform any subclass-specific Update. Reimplemented from vtkAbstractTransform.

void vtkLandmarkTransform::InternalDeepCopy (  vtkAbstractTransform *    transform )  [protected, virtual]

This method does no type checking, use DeepCopy instead. Reimplemented from vtkHomogeneousTransform.
