binaryhorizon - Man Page

A system of path tracing particles evolves continuously.


binaryhorizon [--fps] [--install] [--noinstall] [--mono] [--root] [--window-id number] [--visual visual] [--window]  [--window-id window-id] [--color] [--no-color] [--growth-delay delayms] [--particle-number particles] [--duration secs] [--bicolor] [--monocolor]


A system of path tracing particles evolves continuously from an initial horizon, alternating between colors.


binaryhorizon accepts the following options:


Display the current frame rate and CPU load.


Install a private colormap for the window.


If on a color display, pretend we're on a monochrome display.


Don't install a private colormap for the window.


Draw on the root window.

--window-id number

Draw on the specified window.

--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.


Draw on a newly-created window. This is the default.

--window-id window-id

Specify which window id to use.

--color (Default)

Particles have random generated colors that gradually change over time.


Use the original black and white visualization.

--bicolor (Default)

Particles have 2 random colors, starting as white and black.


Particles have 2 colors, one starting as white and gradually changing, and one staying black.

--fade (Default)

Particles gradually fade between colors over time.


Every particle is a random color.

--growth-delay delayms (Default: 10000)

Delay in ms between growth cycles. More delay, slower (but less CPU intensive).

--particles-number particles (Default: 5000)

The number of particles in the system. With more particles the fps can also be affected.

--duration secs (Default: 30)

How long between full resets.



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.


The window ID to use with --root.
