SYNOPSIS

       cubicgrid  [--display  host:display.screen]  [--visual  visual]  [--window] [--root] [--window-id number]
       [--install] [--delay microseconds] [--mono] [--speed number] [--zoom number] [--ticks number] [--bigdots]
       [--fps] [--symmetry crystalographic symmetry]

DESCRIPTION

       This  program  shows the view of an observer located inside a set of points arranged to a 3D lattice.  As
       the lattice rotates, various view-throughs appear and evolve.  A simple idea with interesting results.

OPTIONS

       cubicgrid 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 microseconds
               How long to pause between frames.  Default is 20000, or 0.02 second.

       --mono  Draw in black and white.  If not used, a fixed all-color scheme is chosen.

       --speed number
               The  maximum speed of the rotation.  The actual speed and axis change smoothly for better effect.
               0.5 - 10.  The default is 1.0.

       --zoom number
               Size of the lattice.  Ideally it should fill all the screen, but one may find other  values  also
               interesting.  5 - 50.  The default of 20 should do for common screen aspect ratios.

       --ticks number
               The count of points drawn along every axis.  10 - 100.  The default is 30.

       --bigdots
               Draw the points twice as big.

       --fps   Display the current frame rate, CPU load, and polygon count.

       --symmetry Symmetry
               Which crystalographic symmetry system to use. One of "auto", "cubic", or "hexagonal". "auto" will
               randomly select between symmetry systems.

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.
