3 mirrorblob - Draws a wobbly blob that distorts the image behind it.

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.
