DESCRIPTION

16       Draws a wobbling blob, making use of alpha blending, fog, textures, and
17       lighting, plus a ``frames per second'' meter so that you can  tell  how
18       fast your graphics card is... Requires OpenGL.

OPTIONS

21       --visual visual
22               Specify  which  visual  to use.  Legal values are the name of a
23               visual class, or the id number (decimal or hex) of  a  specific
24               visual.
25
26       --window
27               Draw on a newly-created window.  This is the default.
28
29       --root  Draw on the root window.
30
31       --window-id number
32               Draw  on  the specified window.  --wire Render in wireframe in‐
33               stead of solid.
34
35       --delay number
36               Per-frame delay, in microseconds.  Default:  10000  (0.01  sec‐
37               onds.).
38
39       --fog | --no-fog
40               Whether to enable fog.
41
42       --walls | --no-walls
43               Add walls for blob to hit.
44
45       --colour | --no-colour
46               Draw  coloured  blob.   If also textured, the texture will have
47               color mixed in.
48
49       --texture | --no-texture
50               Whether to wrap a texture image on the blob.
51
52       --offset_texture | --no-offset_texture
53               Whether to ofset the texture calculations to only use a  region
54               of the image
55                under the blob.  This works well with a semi-transparent blob.
56
57       --blend | --no-blend
58               Whether  to  draw  a transparent blob. (see also offset_texture
59               above)
60
61       --antialias | --no-antialias
62               Whether to antialias lines.
63
64       --resolution number
65               Resolution of the tessellation used to calculate and  draw  the
66               blob.  Larger
67                numbers  give  a  smoother blob but increase calculation times
68               exponentially.
69
70       --bumps number
71               Number of bumps used to distort the blob.
72
73       --hold-time number
74               Time until loading a new image.
75
76       --fade-time number
77               Time taken to transition between images.
78
79       --zoom number
80               Size multiplier for blob.
81
82       --fps   Display the current frame rate, CPU load, and polygon count.
83

ENVIRONMENT

85       DISPLAY to get the default host and display number.
86
87       XENVIRONMENT
88               to get the name of a resource file that  overrides  the  global
89               resources stored in the RESOURCE_MANAGER property.
90
91       XSCREENSAVER_WINDOW
92               The window ID to use with --root.
