nerverot(6) XScreenSaver manual nerverot(6) NAME nerverot - induces edginess in the viewer SYNOPSIS nerverot [--display host:display.screen] [--foreground color] [--background color] [--window] [--root] [--window-id number][--mono] [--install] [--vi- sual visual] [--db] [--no-db] [--colors integer] [--delay microseconds] [--count integer] [--line-width integer] [--event-chance fraction] [--iter-amt fraction] [--nervousness fraction] [--max-nerve-radius frac- tion] [--min-radius integer] [--max-radius integer] [--min-scale fraction] [--max-scale fraction] [--fps] DESCRIPTION The goal of nerverot is to be interesting and compelling to watch, yet in- duce a state of nervous edginess in the viewer. This manpage describes v1.3 of the program. OPTIONS 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-buffer- ing 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, re- source 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 max- Iters. --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 maxN- erveRadius. --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(win- dowHeight,windowWidth), in the range 0..10. Defaults to 0.6, re- source minScale. --max-scale fraction The maximum overall scale of drawing, as a fraction of min(win- dowHeight,windowWidth), in the range 0..10. Defaults to 1.75, re- source maxScale. --fps Display the current frame rate and CPU load. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root. X RESOURCES There are resource equivalents for each option, noted above. BUGS nerverot should have more models. XDBE should be detected and used, if available.
