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.
24
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
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.
