[vtk-developers] vtkArrayCalculator enhancement

Sounds intruiging.  I previously toyed with the idea of adding the ability
to use a point's location in the formula but never implemented it.  In my
case I needed to compute a cartesian vector's cylindrical R component for an
isosurface extraction (radial field strength).  I wound up just doing it

But allowing the user to "deform" the mesh through the Array Calculator...
I'm not an expert here, but won't that wreak major havoc with the vtk
Pipeline (Ghost Cells, normals, range/extents)?
