plot3-fb — display 3-D UNIX plot on a framebuffer
plot3-fb [-id] [-O|o] [-t
displays a BRL extended three dimensional UNIX plot file on a framebuffer.
is used to select the display device (see

Alternatively, the framebuffer may be explicitly specified

By default, the display size is assumed to be 512x512 pixels.
flags allow different screen sizes to be set. The plotting space
will fill the given screen dimensions. No attempt is made at present
to preserve aspect.
flag is for overlay mode, where the current framebuffer image will
be left in the background.
flag causes the rasterized image to be plotted immediately, rather
than buffering up rasterized data into bands. While useful for
quick feedback on small plots, this mode is generally more expensive
in CPU time.
flag outputs a very verbose debugging stream to standard error
listing every UNIX plot command
and the corresponding framebuffer coordinates.
flag causes all lines to be thickened perpendicular to their length,
to the given number of pixels.
This is especially useful when making images for recording on videotape,
as single pixel lines are difficult to resolve.
The thickening will be reduced so that a
line will never be wider than it is long.
If file.plot3 is not specified, the plot commands are read from standard input.
Note that 3-D UNIX plot is a superset of the standard UNIX plot format, thus this program can display normal plot files as well.
