NAME

       plpoin3 - Plot a glyph at the specified 3D points

SYNOPSIS

       plpoin3(n, x, y, z, code)

DESCRIPTION

       Plot  a  glyph  at  the  specified 3D points.  (This function is largely superseded by plstring3(3plplot)
       which gives access to many[!] more glyphs.) Set up the call to this function similar to what is done  for
       plline3(3plplot).  code=-1  means try to just draw a point.  Right now it's just a move and a draw at the
       same place.  Not ideal, since a sufficiently intelligent output device may optimize it away, or there may
       be  faster  ways of doing it.  This is OK for now, though, and offers a 4X speedup over drawing a Hershey
       font "point" (which is actually diamond shaped and therefore takes 4 strokes to draw).  If 0 < code < 32,
       then  a  useful (but small subset) of Hershey symbols is plotted.  If 32 <= code <= 127 the corresponding
       printable ASCII character is plotted.

       Redacted form: plpoin3(x, y, z, code)

       This function is not used in any example.

ARGUMENTS

       n (PLINT(3plplot), input)
              Number of points in the x and y vectors.

       x (PLFLT_VECTOR(3plplot), input)
              A vector containing the x coordinates of points.

       y (PLFLT_VECTOR(3plplot), input)
              A vector containing the y coordinates of points.

       z (PLFLT_VECTOR(3plplot), input)
              A vector containing the z coordinates of points.

       code (PLINT(3plplot), input)
              Hershey symbol code (in "ascii-indexed" form with -1 <= code <= 127) corresponding to a  glyph  to
              be plotted at each of the n points.
