DESCRIPTION

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.

OPTIONS

23       nerverot accepts the following options:
24
25       --window
26               Draw on a newly-created window.  This is the default.
27
28       --root  Draw on the root window.
29
30       --window-id number
31               Draw on the specified window.
32
33       --mono  If on a color display, pretend we're on a monochrome display.
34
35       --install
36               Install a private colormap for the window.
37
38       --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
42       --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
50       --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
55       --delay microseconds
56               The interframe delay, in microseconds. Defaults to  10000,  re‐
57               source delay.
58
59       --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
65       --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
70       --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
74       --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
79       --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
84       --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
89       --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
94       --min-radius integer
95               The minimum radius for a blot, in the range 1..100. Defaults to
96               3, resource minRadius.
97
98       --max-radius integer
99               The maximum radius for a blot, in the range 1..100. Defaults to
100               25, resource maxRadius.
101
102       --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
107       --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
112       --fps   Display the current frame rate and CPU load.
113

ENVIRONMENT

115       DISPLAY to get the default host and display number.
116
117       XENVIRONMENT
118               to  get  the  name of a resource file that overrides the global
119               resources stored in the RESOURCE_MANAGER property.
120
121       XSCREENSAVER_WINDOW
122               The window ID to use with --root.
123

X RESOURCES

125       There are resource equivalents for each option, noted above.
126

BUGS

128       nerverot should have more models.
129
130       XDBE should be detected and used, if available.
