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 sec-
                onds.).
 
        -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.
