Strange attractors formed of flows in a 3D differential equation phase
22
space. Features the popular attractors described by \fBLorentz\fP,
23
\fBRössler\fP, \fBBirkhoff\fP and \fBDuffing\fP, and can now discover
24
entirely new attractors by itself.
27
.B \-visual \fIvisual\fP
28
Specify which visual to use. Legal values are the name of a visual class,
29
or the id number (decimal or hex) of a specific visual.
32
Draw on a newly-created window. This is the default.
35
Draw on the root window.
37
.B \-count \fInumber\fP
38
Number of particles in the flow. Default: 3000
40
.B \-size \fInumber\fP
41
Length of particle trails. Negative values indicate
42
randomness. The computational load of a given flow depends on
43
(particle count) * (trail length). Default: -10
45
.B \-cycles \fInumber\fP
46
Timeout before changing objects. 0 - 800000. Default: 10000.
51
turn on/off periodic attractors. These are flows in 2 dependent
52
variables, with a periodic dependence on a third independent variable
53
(eg time). Flow will sometimes choose to start all the particles in
54
the same phase to illustrate the flow's cross-section. Default:
60
turn on/off search for new attractors. If this is enabled, a fraction
61
of the computing cycles is directed to searching a 60-dimensional
62
parameter space for new strange attractors. If periodic flows are
63
enabled, these can be searched too. Watch carefully - you are quite
64
likely to see mathematical objects that have never been seen before,
65
and since the parameters are not recorded, you'll probably never see
66
them again! Default: on
71
turn on/off rotating around attractor. Default: on
76
turn on/off ride in the flow. Default: on
78
If both -rotate and -ride are enabled the viewpoint will occasionally
79
fly between the two views.
84
turn on/off bounding box. Default: on
89
turn on/off double buffering. If Flow runs slowly in full screen, but
90
fast in a smaller window (eg on old graphics cards with too little
91
memory), try turning this option off. Default: on
93
.B \-ncolors \fInumber\fP
94
Number of Colors. Default: 200.
96
.B \-delay \fInumber\fP
97
Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.).
102
to get the default host and display number.
105
to get the name of a resource file that overrides the global resources
106
stored in the RESOURCE_MANAGER property.
