Superclass for gradient estimation.
Use finite differences to estimate gradient.
static vtkFiniteDifferenceGradientEstimator * New()
Construct a vtkFiniteDifferenceGradientEstimator with a SampleSpacingInVoxels of 1.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void UpdateNormals(void) override
Recompute the encoded normals and gradient magnitudes.
a simple class to control print indentation
