Plot a glyph at the specified 3D points. (This function is largely
superseded by plstring3 which gives access to many[!] more glyphs.)
Set up the call to this function similar to what is done for plline3.
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.
code=-1
n
(PLINT
Number of points in the
and
x
vectors.
y
x
(PLFLT_VECTORA vector containing the x coordinates of points.
y
(PLFLT_VECTORA vector containing the y coordinates of points.
z
(PLFLT_VECTORA vector containing the z coordinates of points.
code
(PLINT
Hershey symbol code (in "ascii-indexed" form with -1 <= code <=
127) corresponding to a glyph to be plotted at each of the
points.
n
Redacted form: plpoin3(x, y, z, code)
This function is not used in any example.
