Back in the day, I made a couple of demos where a Hamiltonian path is carved out on a polyhedron. Looking back, I started to wonder about the shape left around the path, and what it means in terms of graph theory. I call this shape the "dual complement" of the path.

The dual of a polyhedron is essentially the result of turning faces into vertices and vice versa. This is shown in the first clip with a snub dodecahedron and its dual, the pentagonal hexecontahedron; to keep the view cleaner, I'm only showing the edges of one at a time.

The duality transformation also affects the edges, but their number remains the same, and there's a 1:1 mapping between the original and dual edges. Each dual edge "cuts through" the original. To make the dual complement of a path, I remove the dual counterpart of each edge in the path, leaving only the stuff on the sides. It's like driving a snow plough along the path, leaving walls of snow on the sides.

For the final view, I combine original Hamiltonian paths with their dual complements.

Space filling vector algorithms tend to use parallel lines to efficently cover an area. This is a type of single-line plot, following a differential growth algorthim.

I use fountain pens in a pen plotter. So video reviews of fountain pens online don't address the things I am interested in. I don't care about how the pen looks, or how it feels in the hand, or that there's a smile engraved on the nib. #algorist #penplotter

And not even paths between dots as in nodes and paths in graph theory, but literally paths that can fill the space between the dots. Which flips the idea of halftones on its head a bit. #algorist #1penup

Uh oh. I designed a 126 meter single line SVG and I’m kind of worried about plotting it.

New logo, pretty proud of this design. It’s to designate plots done with a single line. The logo itself is a single closed line. #penplotter #1penup #design #algorist #atc

From a pile of shit, new life grows. Conway's Game of Life running independently in the 3 colour channels in 64x64 cells with wrap-around topology.

Not much new code here, just added image loading capability to my old pile-up demo of 2D cellular automata.

Mushrooms. Each plot about 50x50mm, made on upcycled cardboard, using a reclaimed gel pen. #miniplot #penplotter #algorist #fungi

A basic algorithm for a basic guy: find the edge points in the binary image and change their colour to that of the target image. Rinse and repeat until the edge no longer moves.

New Year's Redactions

My earlier text redaction demos were done in my OpenGL setup, using a pixelation effect overlaid on a text document. This was rather simple, but it required some manual tweaking to align the pixelation grid with the text. I've now redone the effect in text mode using Python, and besides unifying the text and "graphics" more cleanly, it makes certain extra features easier, such as this incremental redaction. Of course, video sources as used in the previous post also work.

A particular feature of the unified text + graphics process is that redactions won't exceed the length of each line. In the OpenGL version, the draw area had to be limited to the text rectangle manually, but now it works as it should have done all along.

I do love the imperfect transfer from the digital to the physical when it comes to plotting. Although designed with reproducibility in mind, the process has too many random variables - embrace the happy accidents. #penplotter #algorist
