helper class for a ray cast image
a simple class to control print indentation
Definition: vtkIndent.h:113
OpenGL subclass that draws the image to the screen.

void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
