The goal of nerverot is to be interesting and compelling to
watch, yet induce a state of nervous edginess in the viewer. This manpage
describes v1.3 of the program.
accepts the following options:
Draw on a newly-created window. This is the default.
Draw on the root window.
If on a color display, pretend we're on a monochrome display.
Install a private colormap for the window.
Which visual to use. Legal values are the name of a visual class,
or the id number (decimal or hex) of a specific visual.
Use double-buffering (or not, respectively). Double-buffering may make
things look better for larger line widths and/or larger numbers of
blots, but "better" may equate to yielding less of the desired edginess
effect. You'll be calmer after watching the double-buffered variant;
you're more likely to go into epileptic fits with it off. Hence, it
is off (false) by default, resource doubleBuffer.
How many colors should be used (if possible). The colors
form a smooth ramp between two randomly-chosen colors. Defaults to 4,
The interframe delay, in microseconds. Defaults to 10000, resource
The maximum number of iterations (frames) before a new model is
generated. The actual number of iterations per model is a random number
between 1 and this value. Defaults to 1200, resource
How many "blots" to draw at a time. This number may be rounded down to
fit the particularly chosen model, and has a fixed minimum per-model.
Defaults to 250, resource count.
The width of the lines to draw. 0 means an optimized pixel-thick line.
Defaults to 0, resource lineWidth.
The chance, per iteration, for a life-altering event to occur (such as
picking a new rotation target), in the range 0..1. Defaults to 0.2,
The fraction of movement towards a target (such as rotation angle or scale)
that happens per iteration, in the range 0..1. Defaults to 0.01,
How nervous the drawing is, in the range 0..1. This is how jumpy the points
on each blot are. Defaults to 0.3, resource nervousness.
The maximum radius of blot nervousness, as a fraction of the radius of the
blot, in the range 0..1. Defaults to 0.7, resource maxNerveRadius.
The minimum radius for a blot, in the range 1..100. Defaults to 3,
The maximum radius for a blot, in the range 1..100. Defaults to 25,
The minimum overall scale of drawing, as a fraction of
min(windowHeight,windowWidth), in the range 0..10. Defaults to 0.6,
The maximum overall scale of drawing, as a fraction of
min(windowHeight,windowWidth), in the range 0..10. Defaults to 1.75,
to get the default host and display number.
to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
There are resource equivalents for each option, noted above.
