NAME

6       FENCE3 - Draws the projection of a curve, just as CURVE3 does, but with
7       a "fence" of straight line segments that are parallel to one of the
8       three axes and extend from the curve to a specified plane perpendicular
9       to that axis.

SYNOPSIS

12       CALL FENCE3 (U,V,W,N,IOREN,BOT)
13

C-BINDING SYNOPSIS

15       #include <ncarg/ncargC.h>
16
17       void c_fence3 (float *u, float *v, float *w, int n,
18       int ioren, float bot)

DESCRIPTION

21       U,V,W       (input arrays, dimensioned at least N, of type REAL)
22                   contain the U, V, and W coordinates, respectively, of the
23                   points defining the curve whose projection is to be drawn.
24
25       N           (an input expression of type INTEGER) is the number of
26                   points defining the curve.
27
28       IOREN       (an input expression of type INTEGER) is the direction in
29                   which fence lines are to be drawn, as follows:
30
31                   1  Parallel to the U axis.
32
33                   2  Parallel to the V axis.
34
35                   3  Parallel to the W axis.
36
37       BOT         (an input expression of type REAL) specifies where the
38                   bottom of the fence is to be drawn.  For example, if the
39                   fence lines are to be drawn parallel to the W-axis, and
40                   BOT=2., then the bottom of the fence would be the plane
41                   W=2.
42
43                   The word "bottom" may be misleading here; the entire curve
44                   might be below the plane of the "bottom" and the fence
45                   might be horizontal, rather than vertical, in the three-
46                   dimensional space.
47
48       The curve and the fence are drawn in the colors implied by the values
49       of the variables ITHRMJ and ITHRMN, respectively, in the Threed COMMON
50       block
51
52                    COMMON /THRINT/ ITHRMJ,ITHRMN,ITHRTX
53
54       The default value of both ITHRMJ and ITHRMN is 1; user code may change
55       these values.

C-BINDING DESCRIPTION

58       The C-binding argument descriptions are the same as the FORTRAN
59       argument descriptions.

ACCESS

65       To use FENCE3 or c_fence3, load the NCAR Graphics libraries ncarg,
66       ncarg_gks, and ncarg_c, preferably in that order.
