NAME
      grid mesh - draw either a grid or a grid outline at an arbitrary
                  plane position in a 3D field

SUMMARY
      Name        grid mesh

      Type        mapper

      Inputs      field 3D, any data

      Outputs     geometry

      Parameters  NAME                 TYPE
                  Plane choice         radio buttons
                  Plane number         integer slider
                  Draw mesh            toggle

DESCRIPTION
      This module generates an outline or grid mesh at a constant topological
      plane.  The coordinate information of the input field is used to 
      generate the geometry by connecting adjacent nodal positions within a 
      specified plane.

INPUT
      The input data must be an AVS 3D field, but it may have any data type
      at each field point.

OUTPUT
      The output is a geometry object consisting of either an outline of a 
      grid plane or the grid.

PARAMETERS
      Plane choice  -  the desired plane for the grid

      Plane number  -  the index of the plane desired

      Draw mesh     -  a toggle to generate the mesh rather than the outline

EXAMPLE
      The following network shows a typical usage of 3D axis:
