BRLCAD(1)

A multi-device interactive editor for constructing and updating combinatorial solid geometry (CSG) models. See mged(1), and see also Understanding the Preparation and Analysis of Solid Models by Michael John Muuss (enclosed, in the "paper" directory).

A library of functions suitable for interrogation of a CSG solid model, utilizing ray-tracing techniques. See librt(3).

A ray-tracing lighting model, for rendering pictures of mged(1) CSG models. See rt(1), -rtray(1)-, -rtpp(1)-.

Programs to convert mged(1) and -pix(3)- format binary files to a portable ASCII form, and back again. See asc2g(1), -asc2pix(1)-, conv-vg2g(1), g2asc(1), pix2asc(1).

A "message-passing" interface layered on top of TCP network links, to ease construction of network-distributed applications.

A generic frame-buffer library which includes support for a number of display devices, as well as file, network, and debugging interfaces. Most programs which use this library have the letters "fb" in their names. To override your system default frame-buffer, the environment variable FB_FILE can be set. In addition, some commands also support a -F framebuffer option. Note that the disk file format of libfb is that of pix(5), allowing "framebuffer" files to be later processed by any of the "pix" family of programs. See libfb(3), -pix-fb(3)-, pix(5), etc.

TCP-based network server which implements remote frame-buffer services.

A library to handle terminal mode setting on both Berkeley or SystemV machines.

A public-domain version of the UNIX-Plot library which differs from that of the standard -libplot(3)-, by the addition of 3-D primitives, color, floating point coordinate routines, and the use of a file pointer parameter. See libplot3(3), plot3(5).

A Run-Length-Encoding (RLE) library, providing functions originally from the University of Utah in a library package. Note that the current version of this library reads Edition-3 RLE files. See -rle-fb(1)-, -fb-rle(1)-, -rle-pix(1)-, -pix-rle(1)-, -librle(3)-.

A collection of image-handling utilities, each constructed as individual tools intended to be used in combination. See ap-pix(1), bw-fb(1), -bw-imp(1)-, bw-pix(1), -bw3-pix(1)-, bwcrop(1), bwdiff(1), bwfilter(1), bwhist(1), bwmod(1), bwrect(1), bwrot(1), bwscale(1), bwstat(1), -dunncolor(1)-, -dunnsnap(1)-, fb-bw(1), fb-pix(1), -fb-rle(1)-, -fbanim(1)-, fbclear(1), fbcmap(1), -fbcmrot(1)-, fbcolor(1), fbframe(1), fbgrid(1), fbpoint(1), fbzoom(1), gencolor(1), loop(1), pix-bw(1), -pix-bw3(1)-, pix-fb(1), pixbackgnd(1), pixbustup(1), pixdiff(1), pixfilter(1), pixhist(1), pixhist3d-plot3(1), pixhist3d(1), pixinterp2x(1), pixrect(1), pixrot(1), pixscale(1), pixstat(1), pixtile(1), plot3-fb(1), pp-fb(1), -rle-fb(1)-, -rle-pix(1)-, wavelet(1), bw(5), pix(5), plot3(5).

An interactive, termcap-based frame-buffer image editor. See fbed(1).

A program to convert mged(1) models to gift(1) format card deck files. See vdeck(1).

Inverse flag. Pretend origin is in upper left corner of screen, for that good old-fashioned fourth-quadrant behavior.

Various. Typically means clear the screen first.

Various. Typically means zoom-in on current area of display.

WARNING: Behavior is undefined when the -s flag is used in conjunction with the -w or -n flags.

WARNING: Behavior is undefined when the -S flag is used in conjunction with the -W or -N flags.

specifies the number of bytes per sample, where the flag, where the \# character is a literal "pound" or "sharp" sign character, typically found over the numeral "3" on ANSI keyboards. Several programs (like pixrect) can operate on data samples of arbitrary width. For example, a pix(5) format file can often be treated like a bw(5) format file with a width of three bytes per sample.
