gflux - rippling surface graphics hack
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]
The gflux program draws a colourfull animated rippling square rotating
in 3D space.
gflux accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
Specifies the size of the grid in squares. default 19
Specifies the wireframe detail of the squares. default 4
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.
Same as "-mode wire".
0 for smooth shading 1 for flat. default 0
Specifies speed of ripples flowing over the surface. default
-rotationx num -rotationy num -rotationz num
Specifies the speed of rotation of the surface in these axis
Specifies the number of ripple centres at any one time. Values
should be greater than 1. default 3
Specifies the duration of a ripple centre. after this they
fade away to be reborn elsewhere with a different frequency.
Specifies the height of ripples on the surface. default 1.0
Specifies the maximum frequency of ripples. default 3.0
Specifies the size of the viewport. Smaller values fill the
screen with rippling surface. default 1.0
How long to pause between frames. Default is 20000, or 0.02
-fps Display a running tally of how many frames per second are being
rendered. In conjunction with -delay 0, this can be a useful
benchmark of your GL performance.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
