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.
21

OPTIONS

23       nerverot accepts the following options:
24
25       -window Draw on a newly-created window.  This is the default.
26
27       -root   Draw on the root window.
28
29       -mono   If on a color display, pretend we're on a monochrome display.
30
31       -install
32               Install a private colormap for the window.
33
34       -visual visual
35               Which  visual  to  use.   Legal values are the name of a visual
36               class, or the id number (decimal or hex) of a specific visual.
37
38       -db     -no-db Use double-buffering  (or  not,  respectively).  Double-
39               buffering  may  make  things look better for larger line widths
40               and/or larger numbers of blots,  but  "better"  may  equate  to
41               yielding  less of the desired edginess effect. You'll be calmer
42               after watching the double-buffered variant; you're more  likely
43               to go into epileptic fits with it off. Hence, it is off (false)
44               by default, resource doubleBuffer.
45
46       -colors integer
47               How many colors should be used (if possible). The colors form a
48               smooth  ramp between two randomly-chosen colors. Defaults to 4,
49               resource colors.
50
51       -delay microseconds
52               The interframe delay, in microseconds. Defaults to  10000,  re‐
53               source delay.
54
55       -max-iters integer
56               The maximum number of iterations (frames) before a new model is
57               generated. The actual number of iterations per model is a  ran‐
58               dom number between 1 and this value. Defaults to 1200, resource
59               maxIters.
60
61       -count integer
62               How many "blots" to draw at a time. This number may be  rounded
63               down to fit the particularly chosen model, and has a fixed min‐
64               imum per-model.  Defaults to 250, resource count.
65
66       -line-width integer
67               The width of the lines to draw. 0  means  an  optimized  pixel-
68               thick line.  Defaults to 0, resource lineWidth.
69
70       -event-chance fraction
71               The  chance,  per iteration, for a life-altering event to occur
72               (such as picking a new rotation target), in the range 0..1. De‐
73               faults to 0.2, resource eventChance.
74
75       -iter-amt fraction
76               The fraction of movement towards a target (such as rotation an‐
77               gle or scale) that happens per iteration, in  the  range  0..1.
78               Defaults to 0.01, resource iterAmt.
79
80       -nervousness fraction
81               How  nervous  the  drawing  is,  in the range 0..1. This is how
82               jumpy the points on each blot are. Defaults  to  0.3,  resource
83               nervousness.
84
85       -max-nerve-radius fraction
86               The  maximum  radius  of blot nervousness, as a fraction of the
87               radius of the blot, in the range 0..1.  Defaults  to  0.7,  re‐
88               source maxNerveRadius.
89
90       -min-radius integer
91               The minimum radius for a blot, in the range 1..100. Defaults to
92               3, resource minRadius.
93
94       -max-radius integer
95               The maximum radius for a blot, in the range 1..100. Defaults to
96               25, resource maxRadius.
97
98       -min-scale fraction
99               The minimum overall scale of drawing, as a fraction of min(win‐
100               dowHeight,windowWidth), in the range 0..10.  Defaults  to  0.6,
101               resource minScale.
102
103       -max-scale fraction
104               The maximum overall scale of drawing, as a fraction of min(win‐
105               dowHeight,windowWidth), in the range 0..10. Defaults  to  1.75,
106               resource maxScale.
107
108       -fps    Display the current frame rate and CPU load.
109

ENVIRONMENT

111       DISPLAY to get the default host and display number.
112
113       XENVIRONMENT
114               to  get  the  name of a resource file that overrides the global
115               resources stored in the RESOURCE_MANAGER property.
116

X RESOURCES

118       There are resource equivalents for each option, noted above.
119

BUGS

121       nerverot should have more models.
122
123       XDBE should be detected and used, if available.
