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
       maximum 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	ordering along the curve preserves locality: points that close
       together	along the curve	are also close together	in  space.   The  con-
       verse 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 sec-
	       onds.).

       --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.
	       Default:	false;

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

       --closed
	       --open Whether to draw the open	or  closed-path	 variant.  De-
	       fault: 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
	       resources stored	in the RESOURCE_MANAGER	property.

       XSCREENSAVER_WINDOW
	       The window ID to	use with --root.
