mirrorblob - Draws a wobbly blob that distorts the image behind it.
Draws a wobbling blob, making use of alpha blending, fog,
textures, and lighting, plus a ``frames per second'' meter so that you can
tell how fast your graphics card is... Requires OpenGL.
- -visual visual
Specify which visual to use. Legal values are the name of a visual class,
or the id number (decimal or hex) of a specific visual.
Draw on a newly-created window. This is the default.
Draw on the root window.
Render in wireframe instead of solid.
- -delay number
Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.).
- -fog | -no-fog
Whether to enable fog.
- -walls | -no-walls
Add walls for blob to hit.
- -colour | -no-colour
Draw coloured blob. If also textured, the texture will have color mixed in.
- -texture | -no-texture
Whether to wrap a texture image on the blob.
- -offset_texture | -no-offset_texture
Whether to ofset the texture calculations to only use a region of the image
under the blob. This works well with a semi-transparent blob.
- -blend | -no-blend
Whether to draw a transparent blob. (see also offset_texture above)
- -antialias | -no-antialias
Whether to antialias lines.
- -resolution number
Resolution of the tessellation used to calculate and draw the blob. Larger
numbers give a smoother blob but increase calculation times exponentially.
- -bumps number
Number of bumps used to distort the blob.
- -hold-time number
Time until loading a new image.
- -fade-time number
Time taken to transition between images.
- -zoom number
Size multiplier for blob.
