NAME

jigglypuff - save your screen by tormenting your eyes.

SYNOPSIS

jigglypuff [--display host:display.screen] [--visual visual]
[--window] [--root] [--window-id number] [-delay number] [-cycles
number] [-wireframe] [-fps] [-color colorspec] [-spooky] [-complexity
n] [-speed n] [-spherism n] [-hold n] [-distance n] [-damping n]

DESCRIPTION

This draws all manners of obscene, spastic, puffy, vaguely ball-
shaped objects orbiting lazily about the screen, with a dizzying
array of mostly pointless options.

OPTIONS

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

--root Draw on the root window.

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

--delay number
Per-frame delay, in microseconds. Default: 20000 (0.02
seconds.).

--wireframe
Render in wireframe instead of solid. Default: render solid.

--fps Display the current frame rate, CPU load, and polygon count.

-tetra | -no-tetra
Whether to start the shape in the form of a tetrahedron. The
default is to start as a sphere.

-color colorspec
Available options for colorspec are: cycle, flowerbox,
clownpuke, chrome and #xxxxxx (i.e an (old-style) X color
specification.) Default: cycle

-spooky n
This option controls a kind of interesting effect obtained by
using unnormalized normal vectors (how's that for an
oxymoron?) in OpenGL. A value of zero disables the effect.
Other values vary the lengths of the normals proportionally.
Okay, so it's not very spooky. Sue me. Default: 0

-complexity n
Valid options are 1, 2, and 3. Everything else is treated as
though it were 2, which is the default. This controls the
number of polygons in the 'thing'. A value of 1 yields 1024,
and the values go up in powers of 4. (i.e. 4096, 16384.)
note: There is an inherent lack of stability at lower
complexity, which can cause the shape to devolve into a
'flying snotrag'.

-speed n
Controls how fast the blob moves around the screen. Default:
500.

-spherism, -hold, -distance, -damping
These options control the 'jigglyness'. The best way to
explain these is to explain how jigglypuff works. Basically,
the shape is a tetrahedron whose faces are subdivided into a
number of triangles, forming a mesh. Each of the vertices of
the mesh has two different forces applied to it: one
proportional to its distance from the surface of a sphere,
and one proportional to the difference of the distance to
each of its neighbors in the mesh to a given ideal distance.
In short, one tries to move the points into the configuration
of a sphere, and the other tries to push them back into a
tetrahedron. The catch is that the points have inertia, so
they always overshoot their target, and hence they oscillate.
The magnitudes of the two forces is controlled by the options
'spherism' and 'hold'; 'distance' specifies the distance the
vertices seek to keep from their neighbors, with 500
corresponding to the size of the start tetrahedron. e.g. if
you were to give the options '-tetra -spherism 0 -distance
500', you would end up with a stable tetrahedron. The
'damping' option can help to keep the blob from collapsing or
flying apart. The option specifies the speed at which damping
starts, hence lower values mean more damping. Defaults:
spherism: 75; hold: 800; distance: 100; damping: 500.

-random Probably the only parameter you'l ever need. Overrides almost
all of the parameters with random values. The values affected
are: speed, spherism, hold, distance, damping, spooky, color,
wireframe and tetra. Default: off

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.
