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.

-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.

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.
