Detailed Description

a linear transform specified by two 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

static 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]

Reimplemented from vtkLinearTransform.

static int vtkLandmarkTransform::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkLinearTransform.

virtual int vtkLandmarkTransform::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 vtkLinearTransform.

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

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 )

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.

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

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.

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

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.

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

Set the number of degrees of freedom to constrain the solution to. Rigidbody (VTK_LANDMARK_RIGIDBODY): rotation and translation only. Similarity (VTK_LANDMARK_SIMILARITY): rotation, translation and isotropic scaling. Affine (VTK_LANDMARK_AFFINE): collinearity is preserved. Ratios of distances along a line are preserved. The default is similarity.

void vtkLandmarkTransform::SetModeToRigidBody ( ) [inline]

Set the number of degrees of freedom to constrain the solution to. Rigidbody (VTK_LANDMARK_RIGIDBODY): rotation and translation only. Similarity (VTK_LANDMARK_SIMILARITY): rotation, translation and isotropic scaling. Affine (VTK_LANDMARK_AFFINE): collinearity is preserved. Ratios of distances along a line are preserved. The default is similarity.
