void vtkHomogeneousTransform::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.

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.
