Description

  
   This  module draws vectors with arrow heads from UCD input
   showing CELL vector data.
  
   This is a special ucd mapper module designed to make
   representations based on CELL based values rather than
   the more typical NODE based values. If you have CELL based
   values, you should also consider the ucd_cell_to_node module.
   The module will draw both 2D and 3D vectors, as required.
   The Scale dial is simply a length multiplier.
  
This module is intended as a source example for other UCD module
developers.
Restrictions: This relies on AVS version 4.0 or later,
              as READ UCD had cell data bugs in version 3.0.
