NAME

        gflux - rippling surface graphics hack
 

SYNOPSIS

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

        [-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.
