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 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. 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.

XSCREENSAVER_WINDOW
The window ID to use with --root.
