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.
