NAME

       EZISOS - Draws an isosurface.

SYNOPSIS

       CALL EZISOS (F,MU,MV,MW,EYE,SLAB,FISO)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_ezisos (float *f, int mu, int mv, int mw,
       float eye[3], float *slab, float fiso)

DESCRIPTION

       F           (an input array of type REAL, dimensioned MU x MV x MW) is a three-dimensional
                   array of data defining the function f(u,v,w). The entire array (elements
                   F(IU,IV,IW), for IU = 1 to MU, IV = 1 to MV, and IW = 1 to MW) is to be used.
                   The data are considered to lie in a box in 3-space with opposite corners (in
                   the UVW coordinate system) (1.,1.,1.)  and (REAL(MU),REAL(MV),REAL(MW)). The
                   element F(IU,IV,IW) is considered to be the value of the function f at the
                   point (REAL(IU),REAL(IV),REAL(IW)).

       MU          (an input expression of type INTEGER) is the first dimension of the array F.

       MV          (an input expression of type INTEGER) is the second dimension of the array F.

       MW          (an input expression of type INTEGER) is the third dimension of the array F.

       EYE         (an input array of type REAL, dimensioned 3) is the position of the eye in the
                   UVW coordinate system. The eye position, at (EYE(1),EYE(2),EYE(3)), must be
                   outside the box containing the data. The point being looked at is at the
                   center of the data box and the projection plane is perpendicular to the line
                   of sight. While gaining experience with the routine, a good choice for EYE is
                   (5.*REAL(MU),3.5*REAL(MV),2.*REAL(MW)).

       SLAB        (a scratch array of type REAL, dimensioned at least n x n, where "n" is
                   defined to be MAX[MU,MV,MW]+2) is a workspace for ISOSRF.

       FISO        (an input expression of type REAL) is the value of fiso in the equation
                   f(u,v,w)=fiso, which defines the isosurface to be drawn.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the Fortran argument descriptions,
       with the following exceptions:

       f           t is dimensioned mw by mv by mu

       mu          The third dimension of the array f

       mw          The first dimension of the array f

USAGE

       EZISOS is called to draw an isosurface if all of the input array is to be used (rather
       than a subset of it), if ISOSRF's argument IFLAG is to be chosen internally, and if a
       frame advance is to be done after the isosurface is drawn.  If any of these conditions is
       not met, use ISOSRF instead.

EXAMPLES

       Use the ncargex command to see the following relevant example: tisosr, fisissrf.

ACCESS

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