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   (This  function is largely superseded by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.
