Detailed Description

Compute the gradient of a scalar field on a Hyper Tree Grid.

This filter compute the gradient of a given cell scalars array on a Hyper Tree Grid. This result in a new array attached to the original input. This filter does not support masks. In practice the mask is ignored during the processing of this filters and re-attached to the output, leading to masked cell being taken into account for the gradient computation of visible cells. This leads to the gradient being influenced by masked cells. This should only impact cells on the boundary, where gradient is already ill-defined.
