Superclass for gradient estimation.
vtkEncodedGradientEstimator is an abstract superclass for gradient estimation. It takes a scalar input of vtkImageData, computes a gradient value for every point, and encodes this value into a three byte value (2 for direction, 1 for magnitude) using the vtkDirectionEncoder. The direction encoder is defaulted to a vtkRecursiveSphereDirectionEncoder, but can be overridden with the SetDirectionEncoder method. The scale and the bias values for the gradient magnitude are used to convert it into a one byte value according to v = m*scale + bias where m is the magnitude and v is the resulting one byte value.

void vtkEncodedGradientEstimator::SetZeroNormalThreshold | ( | float | v) |
Set / Get the ZeroNormalThreshold - this defines the minimum magnitude of a gradient that is considered sufficient to define a direction. Gradients with magnitudes at or less than this value are given a "zero normal" index. These are handled specially in the shader, and you can set the intensity of light for these zero normals in the gradient shader.
