NAME¶
PERIM3 - Draws the projection of a rectangular perimeter in a plane parallel to
one of the three coordinate planes, with inward-pointing tick marks at
specified intervals.
SYNOPSIS¶
CALL PERIM3 (MAJOR1,MINOR1,MAJOR2,MINOR2,IAXIS,VALUE)
C-BINDING SYNOPSIS¶
#include <ncarg/ncargC.h>
void c_perim3 (int major1, int minor1, int major2, int minor2,
int iaxis, float value)
DESCRIPTION¶
- MAJOR1
- (an input expression of type INTEGER) specifies the number of major
divisions of those sides of the perimeter parallel to direction 1.
(Directions 1 and 2 are defined by the value of IAXIS.) Major divisions
are indicated by tick marks.
- MINOR1
- (an input expression of type INTEGER) specifies the number of minor
divisions per major division along those sides of the perimeter parallel
to direction 1. (Directions 1 and 2 are defined by the value of IAXIS.)
Minor divisions are indicated by tick marks that, by default, are smaller
than the tick marks indicating major divisions.
- MAJOR2
- (an input expression of type INTEGER) specifies the number of major
divisions of those sides of the perimeter parallel to direction 2.
(Directions 1 and 2 are defined by the value of IAXIS.) Major divisions
are indicated by tick marks.
- MINOR2
- (an input expression of type INTEGER) specifies the number of minor
divisions per major division along those sides of the perimeter parallel
to direction 2. (Directions 1 and 2 are defined by the value of IAXIS.)
Minor divisions are indicated by tick marks that, by default, are smaller
than the tick marks indicating major divisions.
- IAXIS
- (an input expression of type INTEGER) specifies which of the three axes
the perimeter is to be perpendicular to and identifies directions 1 and
2:
- 1
- The perimeter is to be perpendicular to the U axis. Direction 1 is
parallel to the V axis and direction 2 is parallel to the W axis.
- 2
- The perimeter is to be perpendicular to the V axis. Direction 1 is
parallel to the U axis and direction 2 is parallel to the W axis.
- 3
- The perimeter is to be perpendicular to the W axis. Direction 1 is
parallel to the U axis and direction 2 is parallel to the V axis.
- VALUE
- (an input expression of type REAL) is the value at which the plane of the
perimeter is to intersect the axis specified by IAXIS. If IAXIS is a 1,
VALUE is a U coordinate; if IAXIS is a 2, VALUE is a V coordinate; and, if
IAXIS is a 3, VALUE is a W coordinate.
Each call to PERIM3 draws a perimeter: a rectangle representing the intersection
of a plane perpendicular to one of the three axes with the box specified by
the arguments UMIN, UMAX, VMIN, VMAX, WMIN, and WMAX in the last call to SET3.
The perimeter can be placed at any desired position along the axis to which it
is perpendicular; it can have inward-pointing major and minor tick marks along
its edges, spaced as specified by the user. Tick marks along two parallel
edges of the perimeter are controlled by one pair of arguments, and tick marks
along the other two parallel edges are controlled by the other pair of
arguments.
Each of the arguments MAJOR1 and MAJOR2 refers to the number of major divisions
(spaces between ticks) rather than to the number of major ticks; counting
those at the ends, there will be one more major tick than there are major
divisions.
Each of the arguments MINOR1 and MINOR2 refers to the number of minor divisions
(spaces between ticks) rather than to the number of minor ticks; in a given
major interval, there will be one fewer minor tick than there are minor
divisions.
The rectangle itself is drawn in the current polyline color, as determined by
the last call to the GKS routine GSPLCI; by default, color index 1 is used.
Major ticks and minor ticks are drawn in the colors implied by the values of
the variables ITHRMJ and ITHRMN in the Threed COMMON block
-
- COMMON /THRINT/ ITHRMJ,ITHRMN,ITHRTX
The default value of both ITHRMJ and ITHRMN is 1; user code may change these
values.
All lines are drawn using the current GKS line width scale factor, as set by the
last call to the GKS routine GSLWSC.
C-BINDING DESCRIPTION¶
The C-binding argument descriptions are the same as the FORTRAN argument
descriptions.

ACCESS¶
To use PERIM3 or c_perim3, load the NCAR Graphics libraries ncarg, ncarg_gks,
and ncarg_c, preferably in that order.
