NAME
     hilbert - 3D Hilbert fractal.

SYNOPSIS
     hilbert   [--display   host:display.screen]  [--visual  visual]  [--window]
     [--root] [--window-id number] [--delay  number]  [--speed	ratio]	[--depth
     number]  [--spin]	[--wander]  [-2d] [-3d] [--closed] [--open] [--max-depth
     number] [--thickness ratio] [--wireframe] [--fps]

DESCRIPTION
     This draws the recursive Hilbert space-filling curve, in  both  2D  and  3D
     variants.	 It incrementally animates the growth and recursion to the maxi-
     mum depth, then unwinds it back.

     The Hilbert path is a single contiguous line that can fill a volume without
     crossing itself.  As a data structure, Hilbert paths are useful because or-
     dering along the curve preserves locality: points that close together along
     the curve are also close together in space.  The converse is often, but not
     always, true.  The coloration reflects this.

OPTIONS
     --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.

     --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.

     --delay number
	     Per-frame delay, in microseconds.	Default: 30000 (0.03 seconds.).

     --speed number
	     How fast the animation should run.  Less than 1 for slower, greater
	     than 1 for faster.

     --max-depth number
	     Max depth to descend.  Default: 5, which peaks  at  around  half  a
	     million polygons.

     --spin  --no-spin Whether to rotate the object.  Default: true.

     --wander
	     --no-wander Whether to wander the object around on the screen.  De-
	     fault: false;

     -2d     -3d Whether to draw the 2D or 3D variant. Default: random.

     --closed
	     --open  Whether  to  draw the open or closed-path variant. Default:
	     random.

     --thickness ratio
	     How thick the lines should be.  Default: 0.25.

     --wireframe
	     Render in wireframe instead of solid.

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

ENVIRONMENT
     DISPLAY
	     to get the default host and display number.

     XENVIRONMENT
	     to get the name of a resource file that overrides	the  global  re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
