8 The goal of \fInerverot\fP is to be interesting and compelling to
9 watch, yet induce a state of nervous edginess in the viewer. This manpage
10 describes v1.2 of the program.
13 accepts the following options:
16 Draw on a newly-created window. This is the default.
19 Draw on the root window.
22 If on a color display, pretend we're on a monochrome display.
25 Install a private colormap for the window.
27 .B \-visual \fIvisual\fP
28 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.
33 Use double-buffering (or not, respectively). Double-buffering may make
34 things look better for larger line widths and/or larger numbers of
35 blots, but "better" may equate to yielding less of the desired edginess
36 effect. You'll be calmer after watching the double-buffered variant;
37 you're more likely to go into epileptic fits with it off. Hence, it
38 is off (false) by default, resource \fIdoubleBuffer\fP.
40 .B \-colors \fIinteger\fP
41 How many colors should be used (if possible). The colors
42 form a smooth ramp between two randomly-chosen colors. Defaults to 4,
43 resource \fIcolors\fP.
45 .B \-delay \fImicroseconds\fP
46 The interframe delay, in microseconds. Defaults to 10000, resource
49 .B \-count \fIinteger\fP
50 How many "blots" to draw at a time. This number may be rounded down to
51 fit the particularly chosen model, and has a fixed minimum per-model.
52 Defaults to 250, resource \fIcount\fP.
54 .B \-line-width \fIinteger\fP
55 The width of the lines to draw. 0 means an optimized pixel-thick line.
56 Defaults to 0, resource \fIlineWidth\fP.
58 .B \-event-chance \fIfraction\fP
59 The chance, per iteration, for a life-altering event to occur (such as
60 picking a new rotation target), in the range 0..1. Defaults to 0.2,
61 resource \fIeventChance\fP.
63 .B \-iter-amt \fIfraction\fP
64 The fraction of movement towards a target (such as rotation angle or scale)
65 that happens per iteration, in the range 0..1. Defaults to 0.01,
66 resource \fiterAmt\fP.
68 .B \-nervousness \fIfraction\fP
69 How nervous the drawing is, in the range 0..1. This is how jumpy the points
70 on each blot are. Defaults to 0.3, resource \fInervousness\fP.
72 .B \-max-nerve-radius \fIfraction\fP
73 The maximum radius of blot nervousness, as a fraction of the radius of the
74 blot, in the range 0..1. Defaults to 0.7, resource \fImaxNerveRadius\fP.
76 .B \-min-radius \fIinteger\fP
77 The minimum radius for a blot, in the range 1..100. Defaults to 3,
78 resource \fIminRadius\fP.
80 .B \-max-radius \fIinteger\fP
81 The maximum radius for a blot, in the range 1..100. Defaults to 25,
82 resource \fImaxRadius\fP.
84 .B \-min-scale \fIfraction\fP
85 The minimum overall scale of drawing, as a fraction of
86 \fImin(windowHeight,windowWidth)\fP, in the range 0..10. Defaults to 0.6,
87 resource \fIminScale\fP.
89 .B \-max-scale \fIfraction\fP
90 The maximum overall scale of drawing, as a fraction of
91 \fImin(windowHeight,windowWidth)\fP, in the range 0..10. Defaults to 1.75,
92 resource \fImaxScale\fP.
97 to get the default host and display number.
100 to get the name of a resource file that overrides the global resources
101 stored in the RESOURCE_MANAGER property.
103 There are resource equivalents for each option, noted above.
106 should have more models.
