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 Draw on a newly-created window. This is the default.
26 -root Draw on the root window.
28 -mono If on a color display, pretend we're on a monochrome display.
30 -install
32 Install a private colormap for the window.
33 -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 -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 -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 -delay microseconds
52 The interframe delay, in microseconds. Defaults to 10000, re‐
53 source delay.
54 -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 -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 -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 -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 -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 -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 -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 -min-radius integer
91 The minimum radius for a blot, in the range 1..100. Defaults to
92 3, resource minRadius.
93 -max-radius integer
95 The maximum radius for a blot, in the range 1..100. Defaults to
96 25, resource maxRadius.
97 -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 -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 -fps Display the current frame rate and CPU load.
109
111 DISPLAY to get the default host and display number.
112 XENVIRONMENT
114 to get the name of a resource file that overrides the global
115 resources stored in the RESOURCE_MANAGER property.
116
118 There are resource equivalents for each option, noted above.
119
121 nerverot should have more models.
122 XDBE should be detected and used, if available.
