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.
