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.
