10 [-root] [-delay number] [-cycles number] [-wireframe] [-fps] [-color

12 [-distance n] [-damping n]

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
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 -window Draw on a newly-created window. This is the default.
26 -root Draw on the root window.
28 -delay number
30 Per-frame delay, in microseconds. Default: 20000 (0.02 sec‐
31 onds.).
32 -wireframe
34 Render in wireframe instead of solid. Default: render solid.
35 -fps | -no-fps
37 Display frames per second. Default: off.
38 -tetra | -no-tetra
40 Whether to start the shape in the form of a tetrahedron. The
41 default is to start as a sphere.
42 -color colorspec
44 Available options for colorspec are: cycle, flowerbox, clown‐
45 puke, chrome and #xxxxxx (i.e an (old-style) X color specifica‐
46 tion.) Default: cycle
47 -spooky n
49 This option controls a kind of interesting effect obtained by
50 using unnormalized normal vectors (how's that for an oxymoron?)
51 in OpenGL. A value of zero disables the effect. Other values
52 vary the lengths of the normals proportionally. Okay, so it's
53 not very spooky. Sue me. Default: 0
54 -complexity n
56 Valid options are 1, 2, and 3. Everything else is treated as
57 though it were 2, which is the default. This controls the num‐
58 ber of polygons in the 'thing'. A value of 1 yields 1024, and
59 the values go up in powers of 4. (i.e. 4096, 16384.)
60 note: There is an inherent lack of stability at lower complex‐
61 ity, which can cause the shape to devolve into a 'flying sno‐
62 trag'.
63 -speed n
65 Controls how fast the blob moves around the screen. Default:
66 500.
67 -spherism, -hold, -distance, -damping
69 These options control the 'jigglyness'. The best way to explain
70 these is to explain how jigglypuff works. Basically, the shape
71 is a tetrahedron whose faces are subdivided into a number of
72 triangles, forming a mesh. Each of the vertices of the mesh
73 has two different forces applied to it: one proportional to its
74 distance from the surface of a sphere, and one proportional to
75 the difference of the distance to each of its neighbors in the
76 mesh to a given ideal distance. In short, one tries to move the
77 points into the configuration of a sphere, and the other tries
78 to push them back into a tetrahedron. The catch is that the
79 points have inertia, so they always overshoot their target, and
80 hence they oscillate. The magnitudes of the two forces is con‐
81 trolled by the options 'spherism' and ´hold'; 'distance' speci‐
82 fies the distance the vertices seek to keep from their neigh‐
83 bors, with 500 corresponding to the size of the start tetrahe‐
84 dron. e.g. if you were to give the options '-tetra -spherism 0
85 -distance 500', you would end up with a stable tetrahedron. The
86 'damping' option can help to keep the blob from collapsing or
87 flying apart. The option specifies the speed at which damping
88 starts, hence lower values mean more damping. Defaults:
89 spherism: 75; hold: 800; distance: 100; damping: 500.
90 -random Probably the only parameter you'l ever need. Overrides almost
92 all of the parameters with random values. The values affected
93 are: speed, spherism, hold, distance, damping, spooky, color,
94 wireframe and tetra. Default: off
95
97 DISPLAY to get the default host and display number.
98 XENVIRONMENT
100 to get the name of a resource file that overrides the global
101 resources stored in the RESOURCE_MANAGER property.
