abstract base class for most VTK objects
Definition vtkObject.h:57
OpenGL rendering window.
Base class for OpenGL texture management of scalar color, opacity and gradient opacity lookup tables.
void InternalUpdate(vtkObject *func, int blendMode, double sampleDistance, double unitDistance, int filterValue) override
Update the internal texture object using the opacity transfer function.
static vtkOpenGLVolumeOpacityTable * New()
bool NeedsUpdate(vtkObject *func, double scalarRange[2], int blendMode, double sampleDistance) override
Test whether the internal function needs to be updated.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
