vect3(3NCARG)


NAME

   VECT3 - Defines the second and all subsequent points in a sequence of
   points connected by straight-line segments, the projections of which
   are to be drawn. (FRST3 is called for the first point in the sequence
   and VECT3 is called for the rest.)

SYNOPSIS

   CALL VECT3 (U,V,W)

C-BINDING SYNOPSIS

   #include <ncarg/ncargC.h>

   void c_vect3 (float u, float v, float w)

DESCRIPTION

   U,V,W       (input expressions of type REAL) are the coordinates of a
               point in 3-space to the projection of which a line is to be
               drawn.

   Each call to FRST3 moves a conceptual "pen" to the new starting point
   for a sequence of line draws.  Each call to VECT3 draws a line from the
   current pen position to a new pen position and then makes that the
   current pen position.

   Line segments are drawn in the current polyline color, as determined by
   the last call to the GKS routine GSPLCI; by default, color index 1 is
   used.  Line width is determined by the last call to the GKS routine
   GSLWSC; by default, the value of the line width scale factor is 1.

   Note that the routines FRST3 and VECT3 do not flush the SPPS pen-move
   buffer.  In fact, to have them do so would entirely defeat the purpose
   of that buffer.  Therefore, if your last call was to the routine VECT3
   and you are about to call GKS routines to change color or line width,
   you must first call the SPPS routine PLOTIF to flush the buffer;
   otherwise, the color and line width changes will affect line draws
   flushed from the buffer later.

C-BINDING DESCRIPTION

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

EXAMPLES

   Use the ncargex command to see the following relevant examples:
   fthex01, fthex02, fthex03.

ACCESS

   To use VECT3 or c_vect3, load the NCAR Graphics libraries ncarg,
   ncarg_gks, and ncarg_c, preferably in that order.
