DESCRIPTION

16       The  gflux program draws a colourfull animated rippling square rotating
17       in 3D space.
18

OPTIONS

20       gflux accepts the following options:
21
22       -window Draw on a newly-created window.  This is the default.
23
24       -root   Draw on the root window.
25
26       -install
27               Install a private colormap for the window.
28
29       -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
34       -squares num
35               Specifies the size of the grid in squares. default 19
36
37       -resolution num
38               Specifies the wireframe detail of the squares. default 4
39
40       -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
46               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
53       -wireframe
54               Same as "-mode wire".
55
56       -flat num
57               0 for smooth shading 1 for flat. default 0
58
59       -speed num
60               Specifies speed of ripples flowing over  the  surface.  default
61               0.05
62
63       -rotationx num -rotationy num -rotationz num
64               Specifies the speed of rotation of the surface in these axis
65
66       -waves num
67               Specifies the number of ripple centres at any one time.  Values
68               should be greater than 1.  default 3
69
70       -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
75       -waveHeight num
76               Specifies the height of ripples on the surface. default 1.0
77
78       -waveFreq num
79               Specifies the maximum frequency of ripples. default 3.0
80
81       -zoom num
82               Specifies the size of the viewport.  Smaller  values  fill  the
83               screen with rippling surface. default 1.0
84
85       -delay microseconds
86               How  long  to  pause between frames.  Default is 20000, or 0.02
87               second.
88
89       -fps    Display a running tally of how many frames per second are being
90               rendered.   In  conjunction with -delay 0, this can be a useful
91               benchmark of your GL performance.
92

ENVIRONMENT

94       DISPLAY to get the default host and display number.
95
96       XENVIRONMENT
97               to get the name of a resource file that  overrides  the  global
98               resources stored in the RESOURCE_MANAGER property.
