void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkMTimeType GetMTime() override
The modified time of this filter.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
void SetRenderer(vtkRenderer *ren)
The renderer which will ultimately render these points.
~vtkDistanceToCamera() override
a simple class to control print indentation
