pinion(6)

NAME
pinion - draws a scrolling sequence of interconnected gears

SYNOPSIS
pinion [-display host:display.screen] [-window] [-root] [-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.

-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 a running tally of how many frames per second are being rendered. In conjunction with -delay 0, this can be a useful benchmark of your GL performance.

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.
