NAME
       pl-fb - display 3-D UNIX	plot on	a framebuffer

SYNOPSIS
       pl-fb [-hoid] [-t line_thickness] [-F framebuffer] [-S squaresize]
	     [-W width]	[-N height] [file.plot]

DESCRIPTION
       Pl-fb displays a	BRL extended three dimensional UNIX plot file on a
       framebuffer. The	environment variable

       FB_FILE is used to select the display device (see brlcad(1)). If	this
       variable	is not set, the	default	device for your	system will be used.
       By default, the display size is assumed to be 512x512 pixels.
       Specifying the -h flag, changes the output size to 1024x1024. The
       -S~A squaresize -W~A width	and -N~A	height 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.

       The -o flag is for overlay mode,	where the current framebuffer image
       will be left in the background. The -i 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.	The -d flag outputs a very
       verbose debugging stream	to standard error listing every	UNIX plot
       command and the corresponding framebuffer coordinates. The -t 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.plot is not specified, the plot commands	are read from standard
       in.

       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.
