mirrorblob(6x)

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

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

DESCRIPTION
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.

OPTIONS

--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.

--window
    Draw on a newly-created window. This is the default.

--root
    Draw on the root window.

--window-id number
    Draw on the specified window. --wire 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.

--fps
    Display the current frame rate, CPU load, and polygon count.

ENVIRONMENT

DISPLAY
    to get the default host and display number.

XENVIRONMENT
    to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

XSCREENSAVER_WINDOW
    The window ID to use with --root.
