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.
20
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
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
115 There are resource equivalents for each option, noted above.
116
118 nerverot should have more models.
119
120 XDBE should be detected and used, if available.
