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.
nerverot accepts the following options:
- --window
- Draw on a newly-created window. This is the default.
- --root
- Draw on the root window.
- --window-id number
- Draw on the specified window.
- --mono
- If on a color display, pretend we're on a monochrome display.
- --install
- Install a private colormap for the window.
- --visual
visual
- Which visual to use. Legal values are the name of a visual class, or the
id number (decimal or hex) of a specific visual.
- --db
- --no-db 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.
- --colors
integer
- How many colors should be used (if possible). The colors form a smooth
ramp between two randomly-chosen colors. Defaults to 4, resource
colors.
- --delay
microseconds
- The interframe delay, in microseconds. Defaults to 10000, resource
delay.
- --max-iters
integer
- 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 maxIters.
- --count
integer
- 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.
- --line-width
integer
- The width of the lines to draw. 0 means an optimized pixel-thick line.
Defaults to 0, resource lineWidth.
- --event-chance
fraction
- 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,
resource eventChance.
- --iter-amt
fraction
- 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,
resource iterAmt.
- --nervousness
fraction
- 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.
- --max-nerve-radius
fraction
- 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.
- --min-radius
integer
- The minimum radius for a blot, in the range 1..100. Defaults to 3,
resource minRadius.
- --max-radius
integer
- The maximum radius for a blot, in the range 1..100. Defaults to 25,
resource maxRadius.
- --min-scale
fraction
- The minimum overall scale of drawing, as a fraction of
min(windowHeight,windowWidth), in the range 0..10. Defaults to 0.6,
resource minScale.
- --max-scale
fraction
- The maximum overall scale of drawing, as a fraction of
min(windowHeight,windowWidth), in the range 0..10. Defaults to
1.75, resource maxScale.
- --fps
- Display the current frame rate and CPU load.
- DISPLAY
- to get the default host and display number.
- XENVIRONMENT
- to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
- XSCREENSAVER_WINDOW
- The window ID to use with --root.
There are resource equivalents for each option, noted above.
