NAME

6       EZSRFC - Draws a perspective picture of a function of two variables
7       with hidden lines removed. The function is approximated by a two-
8       dimensional array of heights. Use EZSRFC only if the entire array is to
9       be drawn, the data points are equally spaced in the X-Y plane, there
10       are no stereo pairs, and scaling is chosen internally.
11

SYNOPSIS

13       CALL EZSRFC (Z,M,N,ANGH,ANGV,WORK)
14

C-BINDING SYNOPSIS

16       #include <ncarg/ncargC.h>
17
18       void c_ezsrfc (float *z, int m, int n, float angh, float angv,
19       float *work)
20

DESCRIPTION

22       Z           The M by N array to be drawn.
23
24       M           The first dimension of Z.
25
26       N           The second dimension of Z.
27
28       ANGH        Angle in degrees in the X-Y plane to the line of sight
29                   (counterclockwise from the plus-X axis).
30
31       ANGV        Angle in degrees from the X-Y plane to the line of sight
32                   (positive angles are above the middle Z, negative below).
33
34       WORK        A scratch storage dimensioned at least 2*M*N+M+N.
35

C-BINDING DESCRIPTION

37       The C-binding argument descriptions are the same as the FORTRAN
38       argument descriptions, with the following exceptions:
39
40       z           The n by m array to be drawn.
41
42       m           The second dimension of z.
43
44       n           The first dimension of z.
45

ACCESS

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