bouncingcow - a happy cow on a trampoline in 3D. Moo.


bouncingcow [-display host:display.screen] [-visual visual] [-window] [-root] [-delay number] [-speed number] [-count number] [-texture filename] [-wireframe] [-fps]


It’s very silly.


-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.
-delay number
 Per-frame delay, in microseconds. Default: 30000 (0.03 seconds.).
-speed number
 How fast the cow bounces. Larger for faster. Default: 1.0.
-count number
 How many cows! Default 1.
-texture filename
 An image file to paint on the cow’s hide.

Note that on most systems, GL textures must have dimensions that are a power of two.

-wireframe Render in wireframe instead of solid.
-fps Display the current frame rate, CPU load, and polygon count.


DISPLAY to get the default host and display number.
 to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
