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 Display the current frame rate, CPU load, and polygon count.
37 -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 -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 -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 -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 -speed n
64 Controls how fast the blob moves around the screen. Default:
65 500.
66 -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 -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
94
96 DISPLAY to get the default host and display number.
97 XENVIRONMENT
99 to get the name of a resource file that overrides the global
100 resources stored in the RESOURCE_MANAGER property.
