Description

   The plumb_line module annotates the top surface of
   an irregular 3D field, with red cross hairs over each node.
   The cross hairs are pickable, and drive a line along
   the remaining axis, through the 3D space. The (I,J) index
   for the picked point is shown and can be controlled with the
   X-Y integer dials, and are output on two integer output ports.
   This can be used to control modules such as "orthogonal slicer"
   to create a cutting sheet or a graph plot of the selected
   data section. The picked cross hair changes color to white,
   and a polyline following the mesh is drawn below.
