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]


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.)

       -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.
