pp-fb — display a GIFT pretty-picture file on a frame buffer
pp-fb
reads
file.pp,
determines the size,
and displays a color shaded image represented therein
on a frame buffer.
The
.pp
files are the output of the pretty-picture option of the
gift(1V)
ray-tracing program.
The options are standard
brlcad(1)
options specifying framebuffer, output width, and output height.
Some information pertaining to the color assignment of region identification
numbers and the background color is prompted for on the standard input.
The environment
variable

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.
Commands for manipulating the display are documented on-line.
The file format is not documented anywhere.
