Detailed Description

superclass for homogeneous transformations

vtkHomogeneousTransform provides a generic interface for homogeneous transformations, i.e. transformations which can be represented by multiplying a 4x4 matrix with a homogeneous coordinate.

virtual int vtkHomogeneousTransform::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 vtkTransform, vtkPerspectiveTransform, vtkIterativeClosestPointTransform, vtkLandmarkTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkIdentityTransform, vtkSMPTransform, and vtkLinearTransform.

void vtkHomogeneousTransform::PrintSelf	(	ostream &	os,

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 vtkTransform, vtkPerspectiveTransform, vtkLandmarkTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkIdentityTransform, vtkSMPTransform, and vtkLinearTransform.

Reimplemented from vtkAbstractTransform.

Reimplemented in vtkLinearTransform, vtkIdentityTransform, and vtkSMPTransform.

void vtkHomogeneousTransform::GetMatrix ( vtkMatrix4x4 * m )

Get a copy of the internal transformation matrix.

The transform is Updated first, to guarantee that the matrix is valid.

vtkMatrix4x4* vtkHomogeneousTransform::GetMatrix ( )

inline

Get a pointer to an internal vtkMatrix4x4 that represents the transformation.

An Update() is called on the transform to ensure that the matrix is up-to-date when you get it. You should not store the matrix pointer anywhere because it might become stale.

Definition at line 72 of file vtkHomogeneousTransform.h.

vtkHomogeneousTransform* vtkHomogeneousTransform::GetHomogeneousInverse ( )

inline

Just like GetInverse(), but includes typecast to vtkHomogeneousTransform.
