DESCRIPTION

Draws a stick-man juggling various collections of objects.

OPTIONS

juggler3d accepts the following options:

--display host:display.screen
X11 display to use. Overrides DISPLAY environment variable.

--root Draw on the root window.

--window-id number
Draw on the specified window.

--window
Draw on a newly-created X window. This is the default.

--mono Draw in monochrome.

--install | --noinstall
Turn on/off installing colormap.

--visual visual
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
visual.

--window-id id
Draw on an already existing X window.

--pattern " pattern "
Specify juggling pattern in annotated site-swap notation. In
site-swap notation, the "height" of each throw is given.
E.g., "3" is the height needed to juggle a 3-Cascade. Note
that these sequences need to be chosen carefully, to avoid
collisions.

Annotations indicate relative hand movements or tricks:

- Inside throw (default)
+ Outside throw
= Cross Throw
& Cross Catch
x Cross Throw and Catch
_ Bounce

--pattern "[ pattern ]"
Specify juggling pattern in annotated Adam notation. Adam
notation is a little harder to visualize. Each integer n
represents a cyclic permutation of (0...n). The equivalent
site-swap value is determined by calculating how many of the
permutations it takes to get back to the identity. The
largest number used is the same as the number of objects in
the pattern. The advantage of Adam notation is that these
sequences do not need to be chosen carefully, since all
possible sequences are juggle-able. Annotations are the same
as in site-swap notation.

For example, both of these describe a 3-Shower:

--pattern "+5 1"

--pattern "[+3 1]"

For further examples, see the portfolio list in the source
code.

--tail number
Minimum Trail Length. 0 - 100. Default: 1. Objects may
override this, for example flaming torches always leave a
trail.

--real|--no-real
Turn on/off real-time juggling. Deprecated. There should be
no need to turn off real-time juggling, even on slow systems.
Adjust speed using --count above.

--describe|--no-describe
Turn on/off pattern descriptions.

--balls|--no-balls
Turn on/off Balls.

--clubs|--no-clubs
Turn on/off Clubs.

--torches|--no-torches
Turn on/off Flaming Torches.

--knives|--no-knives
Turn on/off Knives.

--rings|--no-rings
Turn on/off Rings.

--bballs|--no-bballs
Turn on/off Bowling Balls.

--count number
Speed. 50 - 1000. Default: 200. This determines the
expected time interval between a throw and the next catch, in
milliseconds.

--cycles number
Performance Length. 50 - 1000. Default: 1000. Setting this
smaller will force the juggler to switch patterns (and
objects) more often.

--delay delay
Additional delay between frames, in microseconds. Default:
10000. Deprecated. Adjust speed using --count.

--ncolors ncolors
Maximum number of colors to use. Default: 32.

--fps Display the current frame rate and CPU load.

ENVIRONMENT

DISPLAY to get the default host and display number.

XENVIRONMENT
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.

XSCREENSAVER_WINDOW
The window ID to use with --root.
