Poriangle vs GeoMaker Pattern Studio

There's a technique called Delaunay triangulation used in computational geometry. While it has plenty of practical applications, let's skip the technical stuff—filling shapes with triangles just looks cool. Poriangle is a shape editor that lets you draw any shape and fill it with Delaunay-style triangles. Draw, experiment, and have fun creating your own designs.

GeoMaker is a pattern studio that never runs dry. Pick one of 70 generative engines, move its levers, and watch original art redraw instantly — every piece grown from a seed, so anything you love can be brought back, tuned again, and saved to Photos in full resolution. TOUCH THE ART Fifteen engines respond to your fingers. Comb floating ink like real suminagashi marbling. Tap wave crests and clouds into an irezumi background. Fracture kintsugi ceramic and paint the gold vein yourself. Bend a maze through a lens, drag the focus of an op-art illusion, morph a living fractal. Turn on kaleidoscope symmetry and one drag becomes six. THE JAPANESE COLLECTION Made by a tattoo artist, GeoMaker goes unusually deep on classical Japanese pattern: sayagata and higaki frets, asanoha hemp-leaf, seigaiha waves, shippō, kikkō, kagome, yagasuri, uroko, ichimatsu, bishamon kikkō armor, matsukawabishi pine-bark, tatewaku rising steam, hanabishi, raimon thunder scrolls, kumiko lattices, kintsugi, indigo shibori, irezumi waves, clouds and mist, and kiku & sakura florals.
