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
               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 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.
