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


SYNOPSIS
       CALL FENCE3 (U,V,W,N,IOREN,BOT)


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

       void c_fence3 (float *u, float *v, float *w, int n,
       int ioren, float bot)


DESCRIPTION
       U,V,W       (input arrays, dimensioned at least N, of type REAL) contain the U, V, and W
                   coordinates, respectively, of the points defining the curve whose projection
                   is to be drawn.

       N           (an input expression of type INTEGER) is the number of points defining the
                   curve.

       IOREN       (an input expression of type INTEGER) is the direction in which fence lines
                   are to be drawn, as follows:

                   1  Parallel to the U axis.

                   2  Parallel to the V axis.

                   3  Parallel to the W axis.

       BOT         (an input expression of type REAL) specifies where the bottom of the fence is
                   to be drawn.  For example, if the fence lines are to be drawn parallel to the
                   W-axis, and BOT=2., then the bottom of the fence would be the plane W=2.

                   The word "bottom" may be misleading here; the entire curve might be below the
                   plane of the "bottom" and the fence might be horizontal, rather than vertical,
                   in the three-dimensional space.

       The curve and the fence are drawn in the colors implied by the values of the variables
       ITHRMJ and ITHRMN, respectively, 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.


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

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