DESCRIPTION

15       This draws the recursive Hilbert space-filling curve, in both 2D and 3D
16       variants.   It  incrementally  animates the growth and recursion to the
17       maximum depth, then unwinds it back.
18
19       The Hilbert path is a single contiguous line that  can  fill  a  volume
20       without crossing itself.  As a data structure, Hilbert paths are useful
21       because ordering along the curve preserves locality: points that  close
22       together  along  the  curve are also close together in space.  The con‐
23       verse is often, but not always, true.  The coloration reflects this.

OPTIONS

26       --visual visual
27               Specify which visual to use.  Legal values are the  name  of  a
28               visual  class,  or the id number (decimal or hex) of a specific
29               visual.
30
31       --window
32               Draw on a newly-created window.  This is the default.
33
34       --root  Draw on the root window.
35
36       --window-id number
37               Draw on the specified window.
38
39       --delay number
40               Per-frame delay, in microseconds.  Default:  30000  (0.03  sec‐
41               onds.).
42
43       --speed number
44               How  fast  the  animation  should run.  Less than 1 for slower,
45               greater than 1 for faster.
46
47       --max-depth number
48               Max depth to descend.  Default: 5, which peaks at around half a
49               million polygons.
50
51       --spin  --no-spin Whether to rotate the object.  Default: true.
52
53       --wander
54               --no-wander  Whether to wander the object around on the screen.
55               Default: false;
56
57       -2d     -3d Whether to draw the 2D or 3D variant. Default: random.
58
59       --closed
60               --open Whether to draw the open  or  closed-path  variant.  De‐
61               fault: random.
62
63       --thickness ratio
64               How thick the lines should be.  Default: 0.25.
65
66       --wireframe
67               Render in wireframe instead of solid.
68
69       --fps   Display the current frame rate, CPU load, and polygon count.
70

ENVIRONMENT

72       DISPLAY to get the default host and display number.
73
74       XENVIRONMENT
75               to  get  the  name of a resource file that overrides the global
76               resources stored in the RESOURCE_MANAGER property.
77
78       XSCREENSAVER_WINDOW
79               The window ID to use with --root.
