DESCRIPTION

15       This draws all manners of obscene, spastic, puffy, vaguely  ball-shaped
16       objects  orbiting  lazily  about  the  screen, with a dizzying array of
17       mostly pointless options.
18

OPTIONS

20       -visual visual
21               Specify which visual to use.  Legal values are the  name  of  a
22               visual  class,  or the id number (decimal or hex) of a specific
23               visual.
24
25       -window Draw on a newly-created window.  This is the default.
26
27       -root   Draw on the root window.
28
29       -delay number
30               Per-frame delay, in microseconds.  Default:  20000  (0.02  sec‐
31               onds.).
32
33       -wireframe
34               Render in wireframe instead of solid. Default: render solid.
35
36       -fps    Display the current frame rate, CPU load, and polygon count.
37
38       -tetra | -no-tetra
39               Whether  to  start  the shape in the form of a tetrahedron. The
40               default is to start as a sphere.
41
42       -color colorspec
43               Available options for colorspec are: cycle,  flowerbox,  clown‐
44               puke, chrome and #xxxxxx (i.e an (old-style) X color specifica‐
45               tion.) Default: cycle
46
47       -spooky n
48               This option controls a kind of interesting effect  obtained  by
49               using unnormalized normal vectors (how's that for an oxymoron?)
50               in OpenGL.  A value of zero disables the effect.  Other  values
51               vary  the lengths of the normals proportionally.  Okay, so it's
52               not very spooky. Sue me.  Default: 0
53
54       -complexity n
55               Valid options are 1, 2, and 3. Everything else  is  treated  as
56               though  it were 2, which is the default. This controls the num‐
57               ber of polygons in the 'thing'. A value of 1 yields  1024,  and
58               the values go up in powers of 4. (i.e. 4096, 16384.)
59                note: There is an inherent lack of stability at lower complex‐
60               ity, which can cause the shape to devolve into a  'flying  sno‐
61               trag'.
62
63       -speed n
64               Controls  how  fast  the blob moves around the screen. Default:
65               500.
66
67       -spherism, -hold, -distance, -damping
68               These options control the 'jigglyness'. The best way to explain
69               these  is to explain how jigglypuff works. Basically, the shape
70               is a tetrahedron whose faces are subdivided into  a  number  of
71               triangles,  forming  a  mesh.  Each of the vertices of the mesh
72               has two different forces applied to it: one proportional to its
73               distance  from the surface of a sphere, and one proportional to
74               the difference of the distance to each of its neighbors in  the
75               mesh to a given ideal distance. In short, one tries to move the
76               points into the configuration of a sphere, and the other  tries
77               to  push  them  back  into a tetrahedron. The catch is that the
78               points have inertia, so they always overshoot their target, and
79               hence  they oscillate. The magnitudes of the two forces is con‐
80               trolled by the options 'spherism' and ´hold'; 'distance' speci‐
81               fies  the  distance the vertices seek to keep from their neigh‐
82               bors, with 500 corresponding to the size of the start  tetrahe‐
83               dron.  e.g. if you were to give the options '-tetra -spherism 0
84               -distance 500', you would end up with a stable tetrahedron. The
85               'damping'  option  can help to keep the blob from collapsing or
86               flying apart. The option specifies the speed at  which  damping
87               starts,  hence  lower  values  mean  more  damping.   Defaults:
88               spherism: 75; hold: 800; distance: 100; damping: 500.
89
90       -random Probably the only parameter you'l ever need.  Overrides  almost
91               all  of  the parameters with random values. The values affected
92               are: speed, spherism, hold, distance, damping,  spooky,  color,
93               wireframe and tetra.  Default: off
