# 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superseded by **plstring3**(3plplot) which gives access to many[!]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.
