gflux - rippling surface graphics hack
gflux [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay
microseconds] [-fps] [-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]
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 visual.
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 chooseRandomIm-
ages options in the ~/.xscreensaver file; see xscreensaver-demo(1) for more
0 for smooth shading 1 for flat. default 0
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
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. default 50
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 second.
-fps Display a running tally of how many frames per second are being rendered. In con-
junction 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.
It's not unknown for this and other OpenGL hacks to fail under hardware accelaration
(UtahGLX) and take the X server with them. Texture images must be 16x16 or 32x32 or 64x64
