NAME

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

SYNOPSIS

       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]

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.  -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.
