mirrorblob(6) XScreenSaver manual mirrorblob(6)

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

mirrorblob [-display host:display.screen] [-visual visual] [-window] [-root] [-wire] [-delay number] [-fog] [-walls] [-colour] [-texture] [-offset-texture] [-blend] [-antialias] [-resolution number] [-bumps number] [-fade-time number] [-hold-time number] [-zoom number] [-fps]

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.

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. -wire Render in wireframe instead of solid.
Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.).
Whether to enable fog.
Add walls for blob to hit.
Draw coloured blob. If also textured, the texture will have color mixed in.
Whether to wrap a texture image on the blob.
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.
Whether to draw a transparent blob. (see also offset_texture above)
Whether to antialias lines.
Resolution of the tessellation used to calculate and draw the blob. Larger
numbers give a smoother blob but increase calculation times exponentially.
Number of bumps used to distort the blob.
Time until loading a new image.
Time taken to transition between images.
Size multiplier for blob.
Display the current frame rate, CPU load, and polygon count.

to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
