hilbert — 3D Hilbert fractal.
Synopsis
hilbert [-display host:display.screen] [-visual visual] [-window] [-root] [-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.
- -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.
