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 when blend is enabled.
-blend | -no-blend
Whether to enable blending. (see also offset_texture above)
-antialias | -no-antialias
Whether to anti-alias lines.
-x_res number
Number of verticies around the middle row of the blob (see also y_res).
-y_res number
Number of rows of verticies used to calculatethe blob, combined with x_res to
indirectly determine the number of triangles used to draw blob. Larger
numbers give a smoother blob but increase calculation times exponentially.
-field_points number
Number of points used to distort the blob.
-hold_time number
Time until loading a new image.
-fade_time number
Crossfade duration time.
-fps | -no-fps
Whether to show a frames-per-second display at the bottom of the screen.
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.
