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.
- -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.
- -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
- 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.
