OpenGL rendering window.
Base class for OpenGL texture management of scalar color, opacity and gradient opacity lookup tables.
2D Transfer function container for label map mask gradient opacity.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void InternalUpdate(vtkObject *func, int blendMode, double sampleDistance, double unitDistance, int filterValue) override
Update the internal texture object using the 2D image data.
