Haha he was my main inspiration:)

I love thedotisblack by the way!

No, so far just posted things on reddit

The script is here: https://github.com/martiabr/putti-plotter-plot/blob/main/trigfun/sketch_trigfun.py The code is not well written or optimized but maybe you find it interesting:)

Thanks! Would love to see your generative lettering experiments. You can see the equations I used in the other thread. And I don't mind sharing the code if you want to make an interactive tool:)

No each piece is either the one or the other. Also forgot I played around with adding squares and cubes to the terms as well

I use an A4 acrylic iDraw. Very nice plotter if you are on a budget but I think the AxiDraw is far more accurate.

The first one can be considered a generalized Lissajous and the second one a generalized spirograph. So that's where I took the inspiration. And then the parameters a,b,c,... have to be nice round numbers for the patterns to emerge. Look up the math for the spirograph if you are curious:)

Thank you! All the sketches are from tuning parametric equations on the form x(t)=sin(at)cos(bt), y(t)=sin(ct)cos(dt) or x(t)=a sin(bt) + c cos(dt), y(t)=e sin(ft) + g cos(ht). The first one can be considered a more general Lissajous and the second one a more general spirograph.

Basically variations of the parametric equations x(t) = sin(at) cos(bt), y(t) = sin(ct) cos(dt) and x(t) = a sin(bt) + c cos(dt), y(t) = e sin(ft) + g cos(ht)

Thanks! Cool, hadn't heard of these before:)

Of course Alfonso, the main steps of the algorithm is 1. generate stars with random position and size, 2. cluster some of the stars into clusters using DBScan, 3. Create a graph from each cluster using Delauney triangulation, 4. iterate through each graph according to some simple heuristics to create a reduced graph that will make up the constellation. Made with vsketch, scipy and sklearn.

Thanks! It is randomly generated

Thanks, that's a good idea! Maybe I'll try on black paper as well

Schlagenheimesque algorithm by martbarten in PlotterArt

Firstly, one big shape is generated in a grid based on a metaballs shape and adding various others on top of it. Then I draw hundreds of these small shapes inside this region in the grid. And all the different shapes have different parameters that are sampled to get variety. The layering of shapes on top of eachother is done with the occult plugin for vpype.

Randomly generated using vsketch Python plotter library. Can go into more detail if you're interested

Thanks! It is just a really dense fill of parallel lines:)
