       3d - 3D cube console

       3d [-xxx,yyy] [program1-6]

       3d is a LibGGI "middleend", that allows to run up to 6 LibGGI
       applications on one screen, mapped to the six sides of a cube.

       The programs program1 to program6 are invoked and mapped to the cube
       sides after the 3d program itself has started. You can interleave the
       program names with size parameters of the form -xxx,yyy that will ask
       the programs that come later on the commandline to start up in that
       size.  The default size is half that of the visual 3d is running on.

       You can add more programs while 3d is running by setting some
       environment variables and starting them :


       The [0-5] selects on which face of the cube you want the application to

       You should as well set GGI_DEFMODE to a mode with the same color
       organization like the one 3d itself is running on, and the mode, 3d
       believes it should run in, as specified with a size parameter.

       Once 3d is invoked, the program will display the cube with the six
       other applications mapped to it. But you will probably only see
       application number 1 (and maybe 3 from behind), as this is the way the
       cube is oriented. The keyboard is redirected to the application that
       has the blinking border.

       #      is the "escape" key. After pressing it, the blinking border
              should turn red.  All further input now goes to the 3d program
              and is used to manipulate the appearance and behaviour of the

       #      A double-escape is used to send the escape-char '#' itself.

              or any unknown keypress will end the escape mode. The border
              will turn white again and input will go to the bordered

              will make the cube turn along the respective axis.

              will make the cube enlarge/shrink.

       s/S    will stop any cube motion.

       c/C    will center the currently active face (the one with the border)
              in a smooth motion and when this is finished, it will stop all
              motion.  This is a toggle, that gets turned off automatically
              when the final position is reached. That is, you can disable it
              on its way, which will leave the cube spinning in the current

       b/B    will toggle backface culling. In that case, the three "back"
              sides of the cube are not drawn. Looks much less nice, but is
              faster. Use on slow systems.

       a/A    will toggle autoactivation. If this is on, the blinking frame
              will automatically move to the face, that is facing the viewer
              most directly, i.e. the "front" face. This can be quite
              irritating, especially, if the cube is moving fast. But it's
              cool at times ...

       t/T    will toggle transparency. The pixelvalue of 0x00000000 is
              treated as "transparent" usually. This not only looks better,
              but often even improves performance, as there is less to draw.
              However things like shells (nixterm) might be hard to read on a
              colorful background, so you might want to turn it off at times.

       0-5    select the active console that will get input, when you leave
              the escaped mode. The blinking rectangle will move there.
              Together with 'c', this is used to get a particular console to
              the front.

       q/Q    quit 3d. This also tries to kill the apps started from it.
              Externally started apps are _not_ killed. They will continue to
              run and might interfere with future runs of 3d, as they still
              hog the shared memory used to communicate between 3d and the

       f/F (undocumented, may disappear)
              display framerate.

       d/D (undocumented, may disappear)
              display debugging info. Not very useful.

       Too numerous to count.
