Detailed Description

a representation for a 3D widget for manipulating a transfer function

vtkTransferFunctionEditorRepresentation is a superclass for representations associated with subclasses of vtkTransferFunctionEditorWidget. In addition to displaying the nodes / shapes for specifying the transfer function, this class also allows you to display a histogram in the background.
