NAME

       Bivar_params - This document briefly describes all Bivar parameters.

DESCRIPTION

       Bivar currently supports two parameters. The current values may be retrieved using one of
       the routines IDGETI or IDGETR. Parameter values may be reset using the routine IDSETI or
       IDSETR.

       The Bivar parameter descriptions appear below in alphabetical order. Each description
       begins with a line giving the parameter name and the intrinsic FORTRAN type of the
       parameter.

       'ITY' - Integer
              Interpolation Type.  The default value, 0, says that quintic interpolation should
              be done.  The value 1 says to use linear interpolation.

       'TTY' - Integer
              Triangulation Type.  The default value, 0, says to use a triangulation due to C. L.
              Lawson that maximizes the minimum angle occurring in the triangles.  The value 1
              says to use the Delaunay triangulation, which ensures triangles whose circumscribed
              circles have no data points in their interiors.
