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 (This function is largely superseded by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, input)
- Number of points in the x and y arrays.
- x (const PLFLT *, input)
- Pointer to an array with X coordinates of points.
- y (const PLFLT *, input)
- Pointer to an array with Y coordinates of points.
- z (const PLFLT *, input)
- Pointer to an array with Z coordinates of points.
- code (PLINT, 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.
