.TH EZSRFC 3NCARG "March 1993" UNIX "NCAR GRAPHICS" .na .nh .SH 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. .SH SYNOPSIS CALL EZSRFC (Z,M,N,ANGH,ANGV,WORK) .SH C-BINDING SYNOPSIS #include .sp void c_ezsrfc (float *z, int m, int n, float angh, float angv, .br float *work) .SH DESCRIPTION .IP Z 12 The M by N array to be drawn. .IP M 12 The first dimension of Z. .IP N 12 The second dimension of Z. .IP ANGH 12 Angle in degrees in the X-Y plane to the line of sight (counterclockwise from the plus-X axis). .IP ANGV 12 Angle in degrees from the X-Y plane to the line of sight (positive angles are above the middle Z, negative below). .IP WORK 12 A scratch storage dimensioned at least 2*M*N+M+N. .SH C-BINDING DESCRIPTION The C-binding argument descriptions are the same as the FORTRAN argument descriptions, with the following exceptions: .IP z 12 The n by m array to be drawn. .IP m 12 The second dimension of z. .IP n 12 The first dimension of z. .SH EXAMPLES Use the ncargex command to see the following relevant examples: fsrezsrf, tsrfac. .SH ACCESS To use EZSRFC or c_ezsrfc, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order. .SH SEE ALSO Online: surface, surface_params, pwrzs, setr, srface. ncarg_cbind. .sp Hardcopy: NCAR Graphics Fundamentals, UNIX Version .SH COPYRIGHT Copyright (C) 1987-2009 .br University Corporation for Atmospheric Research .br The use of this Software is governed by a License Agreement.
