NAME¶

pinion - draws a scrolling sequence of interconnected gears

SYNOPSIS¶

pinion [--display host:display.screen] [--window] [--root] [--window-id number][--install] [--visual visual] [--delay usecs] [--scroll ratio] [--spin ratio] [--size ratio] [--max-rpm int] [--wireframe] [--fps]

DESCRIPTION¶

The pinion program draws an interconnected set of gears moving across the screen.

OPTIONS¶

pinion accepts the following options:

--window

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

--root

Draw on the root window.

--window-id number

Draw on the specified window.

--install

Install a private colormap for the 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.

--delay usecs

The delay between frames of the animation, in microseconds: default 15000.

--spin ratio

How fast the gears should spin; default 1.0. 2.0 means twice as fast, 0.5 means half as fast.

--scroll ratio

How fast the gears should scroll past the screen; default 1.0. 2.0 means twice as fast, 0.5 means half as fast.

--size ratio

How big the gears should be, on average; default 1.0. 2.0 means twice as large, 0.5 means half as large.

--max-rpm integer

If any gear exceeds the maximum RPM, the current gear train is broken there, and we start a new train. Default: 900 RPM. (At 30 FPS, that's about half a rotation per frame.)

--wireframe

Render in wireframe instead of solid.

--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.

XSCREENSAVER_WINDOW

The window ID to use with --root.
