NAME

       EZSRFC - Draws a perspective picture of a function of two variables with hidden lines
       removed. The function is approximated by a two-dimensional array of heights. Use EZSRFC
       only if the entire array is to be drawn, the data points are equally spaced in the X-Y
       plane, there are no stereo pairs, and scaling is chosen internally.

SYNOPSIS

       CALL EZSRFC (Z,M,N,ANGH,ANGV,WORK)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_ezsrfc (float *z, int m, int n, float angh, float angv,
       float *work)

DESCRIPTION

       Z           The M by N array to be drawn.

       M           The first dimension of Z.

       N           The second dimension of Z.

       ANGH        Angle in degrees in the X-Y plane to the line of sight (counterclockwise from
                   the plus-X axis).

       ANGV        Angle in degrees from the X-Y plane to the line of sight (positive angles are
                   above the middle Z, negative below).

       WORK        A scratch storage dimensioned at least 2*M*N+M+N.

C-BINDING DESCRIPTION

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

       z           The n by m array to be drawn.

       m           The second dimension of z.

       n           The first dimension of z.

EXAMPLES

       Use the ncargex command to see the following relevant examples: fsrezsrf, tsrfac.

ACCESS

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