NAME
     gflux - rippling surface graphics hack

SYNOPSIS
     gflux [--display host:display.screen] [--window] [--root] [--window-id num-
     ber][--install]  [--visual  visual]  [--delay microseconds] [--squares num]
     [--resolution num] [--mode mode] [--flat num]  [--speed  num]  [--rotationx
     num]  [--rotationy  num] [--rotationz num] [--waves num] [--waveChange num]
     [--waveHeight num] [--waveFreq num] [--zoom num] [--wireframe] [--fps]

DESCRIPTION
     The gflux program draws a colourfull animated rippling square  rotating  in
     3D space.

OPTIONS
     gflux 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.

     --install
	     Install a private colormap for the window.

     --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.

     --squares num
	     Specifies the size of the grid in squares. default 19

     --resolution num
	     Specifies the wireframe detail of the squares. default 4

     --mode mode
	     Specifies	the  draw method: wireframe; solid (meaning a solid col-
	     ored surface); light (same as solid, but  with  lighting  effects);
	     checker  (a  texture-mapped checkerboard pattern); or grab (meaning
	     grab an image to manipulate.)

	     When grabbing images, the image will be grabbed from the portion of
	     the screen underlying the window, or from the system's video input,
	     or from a random file on disk, as indicated by  the  grabDesktopIm-
	     ages,   grabVideoFrames,  and  chooseRandomImages	options  in  the
	     ~/.xscreensaver file; see	xscreensaver-settings(1)  for  more  de-
	     tails.

     --wireframe
	     Same as "-mode wire".

     --flat num
	     0 for smooth shading 1 for flat. default 0

     --speed num
	     Specifies speed of ripples flowing over the surface. default 0.05

     --rotationx num --rotationy num --rotationz num
	     Specifies the speed of rotation of the surface in these axis

     --waves num
	     Specifies	the  number  of  ripple centres at any one time.  Values
	     should be greater than 1.	default 3

     --waveChange num
	     Specifies the duration of a ripple centre.  after	this  they  fade
	     away to be reborn elsewhere with a different frequency. default 50

     --waveHeight num
	     Specifies the height of ripples on the surface. default 1.0

     --waveFreq num
	     Specifies the maximum frequency of ripples. default 3.0

     --zoom num
	     Specifies	the size of the viewport. Smaller values fill the screen
	     with rippling surface. default 1.0

     --delay microseconds
	     How long to pause between frames.	Default is 20000, or  0.02  sec-
	     ond.

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

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.
