SYNOPSIS

9       mirrorblob  [-display  host:display.screen]  [-visual visual] [-window]
10       [-root] [-wire] [-delay number] [-fog]  [-walls]  [-colour]  [-texture]

DESCRIPTION

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

OPTIONS

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

ENVIRONMENT

82       DISPLAY to get the default host and display number.
83
84       XENVIRONMENT
85               to get the name of a resource file that  overrides  the  global
86               resources stored in the RESOURCE_MANAGER property.
