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 ef-
fects); 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 op-
tions 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.
