EZSRFC(3NCARG)

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.
