Detailed Description

Computes the gradient magnitude of a 3D scalar field and outputs it as float volume.

This processor internally computes the gradients of the given 3D scalar field and only writes the magnitudes of the gradients to the outport. It yields the same results as when combining a GradientVolumeProcessor and VectorMagnitudeProcessor. However, the intermediate gradient volume is never generated and, thus, this processor is more memory efficient.
