void SetPiecewiseFunction(vtkPiecewiseFunction *t)
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ComputeBounds(double bounds[4]) override
void ComputeTexture() override
Need to be reimplemented by subclasses, ComputeTexture() is called at paint time if the texture is no...
vtkPiecewiseFunction * PiecewiseFunction
~vtkPiecewiseFunctionItem() override
Defines a 1D piecewise function.
Abstract class for ScalarsToColors items.
