9 The goal of \fInerverot\fP is to be interesting and compelling to
10 watch, yet induce a state of nervous edginess in the viewer. This manpage
11 describes v1.3 of the program.
14 accepts the following options:
17 Draw on a newly-created window. This is the default.
20 Draw on the root window.
23 If on a color display, pretend we're on a monochrome display.
26 Install a private colormap for the window.
28 .B \-visual \fIvisual\fP
29 Which visual to use. Legal values are the name of a visual class,
30 or the id number (decimal or hex) of a specific visual.
34 Use double-buffering (or not, respectively). Double-buffering may make
35 things look better for larger line widths and/or larger numbers of
36 blots, but "better" may equate to yielding less of the desired edginess
37 effect. You'll be calmer after watching the double-buffered variant;
38 you're more likely to go into epileptic fits with it off. Hence, it
39 is off (false) by default, resource \fIdoubleBuffer\fP.
41 .B \-colors \fIinteger\fP
42 How many colors should be used (if possible). The colors
43 form a smooth ramp between two randomly-chosen colors. Defaults to 4,
44 resource \fIcolors\fP.
46 .B \-delay \fImicroseconds\fP
47 The interframe delay, in microseconds. Defaults to 10000, resource
50 .B \-max\-iters \fIinteger\fP
51 The maximum number of iterations (frames) before a new model is
52 generated. The actual number of iterations per model is a random number
53 between 1 and this value. Defaults to 1200, resource
56 .B \-count \fIinteger\fP
57 How many "blots" to draw at a time. This number may be rounded down to
58 fit the particularly chosen model, and has a fixed minimum per-model.
59 Defaults to 250, resource \fIcount\fP.
61 .B \-line\-width \fIinteger\fP
62 The width of the lines to draw. 0 means an optimized pixel-thick line.
63 Defaults to 0, resource \fIlineWidth\fP.
65 .B \-event\-chance \fIfraction\fP
66 The chance, per iteration, for a life-altering event to occur (such as
67 picking a new rotation target), in the range 0..1. Defaults to 0.2,
68 resource \fIeventChance\fP.
70 .B \-iter\-amt \fIfraction\fP
71 The fraction of movement towards a target (such as rotation angle or scale)
72 that happens per iteration, in the range 0..1. Defaults to 0.01,
73 resource \fIiterAmt\fP.
75 .B \-nervousness \fIfraction\fP
76 How nervous the drawing is, in the range 0..1. This is how jumpy the points
77 on each blot are. Defaults to 0.3, resource \fInervousness\fP.
79 .B \-max\-nerve\-radius \fIfraction\fP
80 The maximum radius of blot nervousness, as a fraction of the radius of the
81 blot, in the range 0..1. Defaults to 0.7, resource \fImaxNerveRadius\fP.
83 .B \-min\-radius \fIinteger\fP
84 The minimum radius for a blot, in the range 1..100. Defaults to 3,
85 resource \fIminRadius\fP.
87 .B \-max\-radius \fIinteger\fP
88 The maximum radius for a blot, in the range 1..100. Defaults to 25,
89 resource \fImaxRadius\fP.
91 .B \-min\-scale \fIfraction\fP
92 The minimum overall scale of drawing, as a fraction of
93 \fImin(windowHeight,windowWidth)\fP, in the range 0..10. Defaults to 0.6,
94 resource \fIminScale\fP.
96 .B \-max\-scale \fIfraction\fP
97 The maximum overall scale of drawing, as a fraction of
98 \fImin(windowHeight,windowWidth)\fP, in the range 0..10. Defaults to 1.75,
99 resource \fImaxScale\fP.
102 Display the current frame rate and CPU load.
107 to get the default host and display number.
110 to get the name of a resource file that overrides the global resources
111 stored in the RESOURCE_MANAGER property.
113 There are resource equivalents for each option, noted above.
116 should have more models.
118 XDBE should be detected and used, if available.
