The figure below is a curve-stitch design I created when I was in high school. More information about its history can be found on my main Web site, Lionel Deimel’s Farrago. One can view this as an isometric drawing of a cube, where curve-stitch parabolas are drawn using each available pair of segments meeting at a cube vertex. People seem to find the figure strangely mesmerizing.
The purpose of this page is to offer serviceable graphics files of the curve-stitch isometric cube and to indicate the ways in which it can be used (or not). The Creative Commons license for the figure is given below. Please contact me at the e-mail address at the bottom of this page if you want to use the figure for commercial purposes or if you require a slightly different version of the figure (different size, format, line width, number of lines used, etc.).
The graphic of the design shown here is a PNG (Portable Network Graphics) file that is 709 x 801 pixels. Its size is 316.61KB. It should display properly in any modern Web browser. The file name is cube.png. In Firefox running in Windows, you can download the file by right-clicking on it and selecting Save Image As…. Other software combinations make similar download methods available.
The figure was created by hand-coding in PostScript. It was possible to proceed along several paths from the raw PostScript file, but the most satisfactory method for generating this and related figures used GSView to generate an EPS (Encapsulated PostScript) file and a PDF (Portable Document Format) file. The PDF file could then be read by Inkscape, from which a PNG or SVG (Scalable Vector Graphics) file could be created. In principle, one could do all the work in Inkscape, but PostScript, being a real programming language—albeit a somewhat idiosyncratic one—makes it easier to define figures with many lines and to reuse one’s work to construct other related figures.
The 17.19KB SVG file corresponding to the figure above is cube.svg. This file can be displayed at various levels of magnification while always showing relatively sharp lines. Unfortunately, not all browsers display SVG files properly. Click here to display the SVG file in a new browser window. If your browser can display this file—it may do something else, like displaying the contents of the file as text—try using its zoom feature to see how the image remains relatively sharp whatever the magnification. In Firefox for Windows, for example, you can use Ctrl-- and Ctrl-+, respectively, to decrease and increase the size of the image. You can download a compressed version of it, cube.zip, by clicking here.
