18 The goal of nerverot is to be interesting and compelling to watch, yet
19 induce a state of nervous edginess in the viewer. This manpage de‐
20 scribes v1.3 of the program.
21
23 nerverot accepts the following options:
24 --window
26 Draw on a newly-created window. This is the default.
27 --root Draw on the root window.
29 --window-id number
31 Draw on the specified window.
32 --mono If on a color display, pretend we're on a monochrome display.
34 --install
36 Install a private colormap for the window.
37 --visual visual
39 Which visual to use. Legal values are the name of a visual
40 class, or the id number (decimal or hex) of a specific visual.
41 --db --no-db Use double-buffering (or not, respectively). Double-
43 buffering may make things look better for larger line widths
44 and/or larger numbers of blots, but "better" may equate to
45 yielding less of the desired edginess effect. You'll be calmer
46 after watching the double-buffered variant; you're more likely
47 to go into epileptic fits with it off. Hence, it is off (false)
48 by default, resource doubleBuffer.
49 --colors integer
51 How many colors should be used (if possible). The colors form a
52 smooth ramp between two randomly-chosen colors. Defaults to 4,
53 resource colors.
54 --delay microseconds
56 The interframe delay, in microseconds. Defaults to 10000, re‐
57 source delay.
58 --max-iters integer
60 The maximum number of iterations (frames) before a new model is
61 generated. The actual number of iterations per model is a ran‐
62 dom number between 1 and this value. Defaults to 1200, resource
63 maxIters.
64 --count integer
66 How many "blots" to draw at a time. This number may be rounded
67 down to fit the particularly chosen model, and has a fixed min‐
68 imum per-model. Defaults to 250, resource count.
69 --line-width integer
71 The width of the lines to draw. 0 means an optimized pixel-
72 thick line. Defaults to 0, resource lineWidth.
73 --event-chance fraction
75 The chance, per iteration, for a life-altering event to occur
76 (such as picking a new rotation target), in the range 0..1. De‐
77 faults to 0.2, resource eventChance.
78 --iter-amt fraction
80 The fraction of movement towards a target (such as rotation an‐
81 gle or scale) that happens per iteration, in the range 0..1.
82 Defaults to 0.01, resource iterAmt.
83 --nervousness fraction
85 How nervous the drawing is, in the range 0..1. This is how
86 jumpy the points on each blot are. Defaults to 0.3, resource
87 nervousness.
88 --max-nerve-radius fraction
90 The maximum radius of blot nervousness, as a fraction of the
91 radius of the blot, in the range 0..1. Defaults to 0.7, re‐
92 source maxNerveRadius.
93 --min-radius integer
95 The minimum radius for a blot, in the range 1..100. Defaults to
96 3, resource minRadius.
97 --max-radius integer
99 The maximum radius for a blot, in the range 1..100. Defaults to
100 25, resource maxRadius.
101 --min-scale fraction
103 The minimum overall scale of drawing, as a fraction of min(win‐
104 dowHeight,windowWidth), in the range 0..10. Defaults to 0.6,
105 resource minScale.
106 --max-scale fraction
108 The maximum overall scale of drawing, as a fraction of min(win‐
109 dowHeight,windowWidth), in the range 0..10. Defaults to 1.75,
110 resource maxScale.
111 --fps Display the current frame rate and CPU load.
113
115 DISPLAY to get the default host and display number.
116 XENVIRONMENT
118 to get the name of a resource file that overrides the global
119 resources stored in the RESOURCE_MANAGER property.
120 XSCREENSAVER_WINDOW
122 The window ID to use with --root.
123
125 There are resource equivalents for each option, noted above.
126
128 nerverot should have more models.
129 XDBE should be detected and used, if available.
