6 gflux - rippling surface graphics hack
7
9 gflux [-display host:display.screen] [-window] [-root] [-install]
10 [-visual visual] [-delay microseconds] [-squares num] [-resolution num]
11 [-mode mode] [-flat num] [-speed num] [-rotationx num] [-rotationy num]
12 [-rotationz num] [-waves num] [-waveChange num] [-waveHeight num]
13 [-waveFreq num] [-zoom num] [-wireframe] [-fps]
14
16 The gflux program draws a colourfull animated rippling square rotating
17 in 3D space.
18
20 gflux accepts the following options:
21 -window Draw on a newly-created window. This is the default.
23 -root Draw on the root window.
25 -install
27 Install a private colormap for the window.
28 -visual visual
30 Specify which visual to use. Legal values are the name of a
31 visual class, or the id number (decimal or hex) of a specific
32 visual.
33 -squares num
35 Specifies the size of the grid in squares. default 19
36 -resolution num
38 Specifies the wireframe detail of the squares. default 4
39 -mode mode
41 Specifies the draw method: wireframe; solid (meaning a solid
42 colored surface); light (same as solid, but with lighting
43 effects); checker (a texture-mapped checkerboard pattern); or
44 grab (meaning grab an image to manipulate.)
45 When grabbing images, the image will be grabbed from the por‐
47 tion of the screen underlying the window, or from the system's
48 video input, or from a random file on disk, as indicated by the
49 grabDesktopImages, grabVideoFrames, and chooseRandomImages
50 options in the ~/.xscreensaver file; see xscreensaver-demo(1)
51 for more details.
52 -wireframe
54 Same as "-mode wire".
55 -flat num
57 0 for smooth shading 1 for flat. default 0
58 -speed num
60 Specifies speed of ripples flowing over the surface. default
61 0.05
62 -rotationx num -rotationy num -rotationz num
64 Specifies the speed of rotation of the surface in these axis
65 -waves num
67 Specifies the number of ripple centres at any one time. Values
68 should be greater than 1. default 3
69 -waveChange num
71 Specifies the duration of a ripple centre. after this they
72 fade away to be reborn elsewhere with a different frequency.
73 default 50
74 -waveHeight num
76 Specifies the height of ripples on the surface. default 1.0
77 -waveFreq num
79 Specifies the maximum frequency of ripples. default 3.0
80 -zoom num
82 Specifies the size of the viewport. Smaller values fill the
83 screen with rippling surface. default 1.0
84 -delay microseconds
86 How long to pause between frames. Default is 20000, or 0.02
87 second.
88 -fps Display the current frame rate, CPU load, and polygon count.
90
92 DISPLAY to get the default host and display number.
93 XENVIRONMENT
95 to get the name of a resource file that overrides the global
96 resources stored in the RESOURCE_MANAGER property.
