Detailed Description

Class for rendering a markups node.

This class can display a markups node in the scene. It plays a similar role to vtkWidgetRepresentation, but it is simplified and specialized for optimal use in Slicer. It state is stored in the associated MRML display node to avoid extra synchronization mechanisms. The representation only observes MRML node changes, it does not directly process any interaction events directly (interaction events are processed by vtkMRMLAbstractWidget, which then modifies MRML nodes).

This class (and subclasses) are a type of vtkProp; meaning that they can be associated with a vtkRenderer end embedded in a scene like any other vtkActor.
