26
Draws a wobbling blob, making use of alpha blending, fog,
27
textures, and lighting, plus a ``frames per second'' meter so that you can
28
tell how fast your graphics card is... Requires OpenGL.
31
.B \-visual \fIvisual\fP
32
Specify which visual to use. Legal values are the name of a visual class,
33
or the id number (decimal or hex) of a specific visual.
36
Draw on a newly-created window. This is the default.
39
Draw on the root window.
41
Render in wireframe instead of solid.
43
.B \-delay \fInumber\fP
44
Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.).
47
Whether to enable fog.
49
.B \-walls | \-no-walls
50
Add walls for blob to hit.
52
.B \-colour | \-no-colour
53
Draw coloured blob. If also textured, the texture will have color mixed in.
55
.B \-texture | \-no-texture
56
Whether to wrap a texture image on the blob.
58
.B \-bgimage | \-no-bgimage
59
Whether to also draw the texture on the background.
61
.B \-offset_texture | \-no-offset_texture
62
Whether to ofset the texture calculations to only use a region of the image
63
under the blob. This works well when blend is enabled.
65
.B \-blend | \-no-blend
66
Whether to enable blending. (see also offset_texture above)
68
.B \-antialias | \-no-antialias
69
Whether to anti-alias lines.
71
.B \-x_res \fInumber\fP
72
Number of verticies around the middle row of the blob (see also y_res).
74
.B \-y_res \fInumber\fP
75
Number of rows of verticies used to calculatethe blob, combined with x_res to
76
indirectly determine the number of triangles used to draw blob. Larger
77
numbers give a smoother blob but increase calculation times exponentially.
79
.B \-field_points \fInumber\fP
80
Number of points used to distort the blob.
82
.B \-hold_frames \fInumber\fP
83
Number of frames between changing images.
85
.B \-fade_speed \fInumber\fP
86
Speed at which fading occurs when changing images.
89
Whether to show a frames-per-second display at the bottom of the screen.
94
to get the default host and display number.
97
to get the name of a resource file that overrides the global resources
98
stored in the RESOURCE_MANAGER property.
