NAME

       Isosurface - Allows the user to draw a perspective view of the surface defined by the
       equation f(u,v,w)=fiso, where the function f is approximated by a 3-dimensional array of
       data and fiso is a user-specified "isovalue". Contours created by taking slices in any of
       three directions through the surface are drawn with hidden portions of the contour lines
       removed.

SYNOPSIS

       EZISOS - May be called to draw an isosurface.

       ISOSRF - May be called to draw an isosurface.

       ISGETI - Retrieves the current values of various internal parameters affecting the
       behavior of ISOSRF.

       ISGETR - Retrieves the current values of various internal parameters affecting the
       behavior of ISOSRF.

       ISSETI - Gives new values to internal parameters.

       ISSETR - Gives new values to internal parameters.

       PWRZI - Plots characters in three-space when using ISOSRF.

C-BINDING SYNOPSIS

       c_ezisos,
       c_isosrf,
       c_isgeti,
       c_isgetr,
       c_isseti,
       c_issetr,
       c_pwrzi

USER-MODIFIABLE INTERNAL ROUTINES

       None.

ACCESS

       To use Isosurface, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.

MESSAGES

       The error messages described below can be written to the output unit by routines in the
       package Isosurface.  All of these errors are fatal and cause the user's program to
       terminate execution (on the other hand, all of the errors are easily avoided).

       ISGETI OR ISGETR - PARAMETER NAME TOO SHORT - x
                   The argument "PNAM", in a call to ISGETI or ISGETR, is only one character
                   long.

       ISGETI OR ISGETR - PARAMETER NAME NOT KNOWN - xx
                   The argument "PNAM", in a call to ISGETI or ISGETR, begins with two characters
                   that do not constitute one of the legal internal parameter names described in
                   the man page isosurface_params.

       ISSETI OR ISSETR - PARAMETER NAME TOO SHORT - x
                   The argument "PNAM", in a call to ISSETI or ISSETR, is only one character
                   long.

       ISSETI OR ISSETR - PARAMETER NAME NOT KNOWN - xx
                   The argument "PNAM", in a call to ISSETI or ISSETR, begins with two characters
                   that do not constitute one of the legal internal parameter names described in
                   the man page isosurface_params.

       ISINIT - INSTALLATION OF ISOSRF IMPROPERLY DONE
                   This error message means that the screen models used to do hidden-line removal
                   have been found to be improperly dimensioned for the system on which the code
                   is being run. About the only way this can happen is if the distributed code is
                   run on a a machine with sixteen-bit words or if the distributed code has been
                   modified incorrectly.
