NAME
       hilbert - 3D Hilbert fractal.

SYNOPSIS
       hilbert [-display host:display.screen] [-visual visual] [-window]
       [-root] [-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
       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.

       -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.
               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. 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
               resources stored in the RESOURCE_MANAGER property.
