XScreenSaver !!!XScreenSaver NAME SYNOPSIS DESCRIPTION OPTIONS ENVIRONMENT X RESOURCES BUGS SEE ALSO COPYRIGHT AUTHOR ---- !!NAME nerverot - induces edginess in the viewer !!SYNOPSIS __nerverot__ [[-display ''host:display.screen''] [[-foreground ''color''] [[-background ''color''] [[-window] [[-root] [[-mono] [[-install] [[-visual ''visual''] [[-db] [[-no-db] [[-colors ''integer''] [[-delay ''microseconds''] [[-count ''integer''] [[-line-width ''integer''] [[-event-chance ''fraction''] [[-iter-amt ''fraction''] [[-nervousness ''fraction''] [[-max-nerve-radius ''fraction''] [[-min-radius ''integer''] [[-max-radius ''integer''] [[-min-scale ''fraction''] [[-max-scale ''fraction''] !!DESCRIPTION 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. !!OPTIONS ''nerverot'' accepts the following options: __-window__ Draw on a newly-created window. This is the default. __-root__ Draw on the root 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 __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 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 terAmt. __-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''. !!ENVIRONMENT __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. !!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. !!SEE ALSO xscreensaver(1) !!COPYRIGHT Copyright 2000-2001 by Dan Bornstein. All rights reserved.
