NAME
hilbert - 3D Hilbert fractal.
SYNOPSIS
hilbert [-display host:display.screen] [-visual visual] [-window]
[-root] [-delay number] [-speed ratio] [-depth number] [-spin] [-wan-
der] [-2d] [-3d] [-closed] [-open] [-max-depth number] [-thickness ra-
tio] [-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.
-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. 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.
