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.
