static vtkMatrix4x4* vtkMatrix4x4::New ( ) [static]

Construct a 4x4 identity matrix.

Reimplemented from vtkObject.

virtual const char* vtkMatrix4x4::GetClassName ( ) [virtual]

Reimplemented from vtkObject.

Reimplemented from vtkObject.

void vtkMatrix4x4::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.
