NAME
       gflux - rippling surface graphics hack

SYNOPSIS
       gflux   [-display  host:display.screen]	[-window]  [-root]  [-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.

       -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
	       colored	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 por‐
	       tion of the screen underlying the window, or from the  system's
	       video input, or from a random file on disk, as indicated by the
	       grabDesktopImages,  grabVideoFrames,   and   chooseRandomImages
	       options	in  the ~/.xscreensaver file; see xscreensaver-demo(1)
	       for more details.

       -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
	       second.

       -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
	       resources stored in the RESOURCE_MANAGER property.
