Draws a stick-man juggling various collections of objects.
juggler3d accepts the following options:
- -display
host:display.screen
- X11 display to use. Overrides DISPLAY environment variable.
- -root
- Draw on the root 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.
- 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.
