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.
