jigglypuff(6)		      XScreenSaver manual		 jigglypuff(6)

NAME
       jigglypuff - save your screen by tormenting your eyes.

SYNOPSIS
       jigglypuff  [-display  host:display.screen]  [-visual visual] [-window]
       [-root] [-delay number] [-cycles number]	 [-wireframe]  [-fps]  [-color
       colorspec] [-spooky] [-complexity n] [-speed n] [-spherism n] [-hold n]
       [-distance n] [-damping n]

DESCRIPTION
       This draws all manners of obscene, spastic, puffy, vaguely  ball-shaped
       objects	orbiting  lazily  about	 the  screen, with a dizzying array of
       mostly pointless options.

OPTIONS
       -visual visual
	       Specify which visual to use.  Legal values are the  name	 of  a
	       visual  class,  or the id number (decimal or hex) of a specific
	       visual.

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -delay number
	       Per-frame delay, in microseconds.  Default:  20000  (0.02  sec‐
	       onds.).

       -wireframe
	       Render in wireframe instead of solid. Default: render solid.

       -fps    Display the current frame rate, CPU load, and polygon count.

       -tetra | -no-tetra
	       Whether	to  start  the shape in the form of a tetrahedron. The
	       default is to start as a sphere.

       -color colorspec
	       Available options for colorspec are: cycle,  flowerbox,	clown‐
	       puke, chrome and #xxxxxx (i.e an (old-style) X color specifica‐
	       tion.) Default: cycle

       -spooky n
	       This option controls a kind of interesting effect  obtained  by
	       using unnormalized normal vectors (how's that for an oxymoron?)
	       in OpenGL.  A value of zero disables the effect.	 Other	values
	       vary  the lengths of the normals proportionally.	 Okay, so it's
	       not very spooky. Sue me.	 Default: 0

       -complexity n
	       Valid options are 1, 2, and 3. Everything else  is  treated  as
	       though  it were 2, which is the default. This controls the num‐
	       ber of polygons in the 'thing'. A value of 1 yields  1024,  and
	       the values go up in powers of 4. (i.e. 4096, 16384.)
		note: There is an inherent lack of stability at lower complex‐
	       ity, which can cause the shape to devolve into a	 'flying  sno‐
	       trag'.

       -speed n
	       Controls	 how  fast  the blob moves around the screen. Default:
	       500.

       -spherism, -hold, -distance, -damping
	       These options control the 'jigglyness'. The best way to explain
	       these  is to explain how jigglypuff works. Basically, the shape
	       is a tetrahedron whose faces are subdivided into	 a  number  of
	       triangles,  forming  a  mesh.  Each of the vertices of the mesh
	       has two different forces applied to it: one proportional to its
	       distance	 from the surface of a sphere, and one proportional to
	       the difference of the distance to each of its neighbors in  the
	       mesh to a given ideal distance. In short, one tries to move the
	       points into the configuration of a sphere, and the other	 tries
	       to  push	 them  back  into a tetrahedron. The catch is that the
	       points have inertia, so they always overshoot their target, and
	       hence  they oscillate. The magnitudes of the two forces is con‐
	       trolled by the options 'spherism' and ´hold'; 'distance' speci‐
	       fies  the  distance the vertices seek to keep from their neigh‐
	       bors, with 500 corresponding to the size of the start  tetrahe‐
	       dron.  e.g. if you were to give the options '-tetra -spherism 0
	       -distance 500', you would end up with a stable tetrahedron. The
	       'damping'  option  can help to keep the blob from collapsing or
	       flying apart. The option specifies the speed at	which  damping
	       starts,	hence  lower  values  mean  more  damping.   Defaults:
	       spherism: 75; hold: 800; distance: 100; damping: 500.

       -random Probably the only parameter you'l ever need.  Overrides	almost
	       all  of	the parameters with random values. The values affected
	       are: speed, spherism, hold, distance, damping,  spooky,	color,
	       wireframe and tetra.  Default: off

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.
