DESCRIPTION

17       The goal of nerverot is to be interesting and compelling to watch,  yet
18       induce  a  state  of  nervous  edginess  in  the  viewer.  This manpage
19       describes v1.3 of the program.

OPTIONS

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

ENVIRONMENT

108       DISPLAY to get the default host and display number.
109
110       XENVIRONMENT
111               to get the name of a resource file that  overrides  the  global
112               resources stored in the RESOURCE_MANAGER property.
113

X RESOURCES

115       There are resource equivalents for each option, noted above.
116

BUGS

118       nerverot should have more models.
119
120       XDBE should be detected and used, if available.
