abstract class for representing affine transformation widgets
virtual void GetTransform(vtkTransform *t)=0
Retrieve a linear transform characterizing the affine transformation generated by this widget.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ShallowCopy(vtkProp *prop) override
Methods to make this class properly act like a vtkWidgetRepresentation.
~vtkAffineRepresentation() override
a simple class to control print indentation
Definition: vtkIndent.h:34
abstract superclass for all actors, volumes and annotations
Definition: vtkProp.h:54
describes linear transformations via a 4x4 matrix
Definition: vtkTransform.h:55
abstract class defines interface between the widget and widget representation classes
