virtual void InternalUpdate(vtkObject *func, int blendMode, double sampleDistance, double unitDistance, int filterValue)
Internal method to actually update the texture object.
virtual bool NeedsUpdate(vtkObject *func, double scalarRange[2], int blendMode, double sampleDistance)
Test whether the internal function needs to be updated.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual void AllocateTable()
Allocate internal data table.
