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
- 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.
- -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
- -colors integer
- How many colors should be used (if possible). The colors
form a smooth ramp between two randomly-chosen colors. Defaults to 4,
- -delay microseconds
- The interframe delay, in microseconds. Defaults to 10000,
- -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
- -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
- -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
- -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,
- -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.
- Display the current frame rate and CPU load.
- 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.
should have more models.
- XDBE should be detected and used, if available.
