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.


--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.


Draw on a newly-created window.  This is the default.


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.


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


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


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


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

--thickness ratio

How thick the lines should be.  Default: 0.25.


Render in wireframe instead of solid.


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



to get the default host and display number.


to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.


The window ID to use with --root.
