Provided by: libncarg-dev_6.4.0-9_amd64 bug

NAME
       SETR - Establishes certain constants so that SRFACE produces a picture whose size changes with respect to
       the viewer's distance from the object.  It can also be used when making a movie of an object evolving in
       time to keep it positioned properly on the screen, saving computer time in the bargin.  Call it with r0
       negative to turn off this feature.


SYNOPSIS
       SUBROUTINE SETR (XMIN,XMAX,YMIN,YMAX,ZMIN,ZMAX,R0)


C-BINDING SYNOPSIS
       #include <ncarg/ncargC.h>

       void c_setr (float xmin, float xmax, float ymin, float ymax,
       float zmin, float zmax, float r0)


DESCRIPTION
       XMIN,XMAX   Specifies the range of X array that will be passed to SRFACE.

       YMIN,YMAX   Specifies the range of Y array that will be passed to SRFACE.

       ZMIN,ZMAX   Specifies the range of Z array that will be passed to SRFACE.  If a movie is being made of an
                   evolving Z array, ZMIN and ZMAX should contain range of the union of all the Z arrays.  They
                   need not be exact.

       R0          Distance between observer and point looked at when the picture is to fill the screen when
                   viewed from the direction which makes the picture biggest.  If R0 is not positive, then the
                   relative size feature is turned off, and subsequent pictures will fill the screen.


C-BINDING DESCRIPTION
       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.


ACCESS
       To use SETR or c_setr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that
       order.
