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
- 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.
- 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.
