Added a convolution kernel filtering operator for polygons/polylines to https://thi.ng/geom, incl. some useful preset kernels: box filter, triangle, gaussian, all with configurable size...

The image shows effects of various kernel sizes & iterations. Unlike with subdivision smoothing, here each version has the exact same number of vertices, only their positions are impacted: orange = box, magenta = triangle, blue = gaussian

(For now the operator is only implemented for polygons (also w/ holes) & polylines, but can be extended to other shape types...)

Added a new[1] configurable curve subdivision kernel for https://thi.ng/geom to (iteratively) subdivide polygons/polylines with displacement, allowing for super compact code, infinite variation, and beautiful results like shown...

[1] Actually been using this approach since 2010, initially for 3D mesh subdivisions (3rd image)

So many new and improved features (+ new shape types) coming to https://thi.ng/geom (more about those soon) — for now a new tiny example to show point classification (inside/boundary/outside) for polygons:

Ticked off one from the bucket list yesterday: Gleirsch canyon, carved out by one of the earliest tributaries of the Isar river, both with an incredibly beautiful turquoise water color. The canyon itself is one of the wildest & Tolkienesque I've ever been too, higher up parts then offering amazing views of the epic Karwendel main range... ❤️

Just received my sponsorship shirt for the thi.ng library ❤️ I have seen the logo many times, but now with this really close „zoom“ i realise there is a slight offset on the second n stripe 🤯. Well done typography by @toxi 😁

Since some of you seem to enjoy these tessellation experiments, here's an old projection mapping installation project of mine for which I combined similar patterns with digital fabrication (laser cutting & cutting plotters) to produce two Victorian-style room dividers with 620 handfolded paper cones, which were then used as 3D projection surface. Visitors could use an iPad app, housed in a small dolly table (also laser cut), to produce custom animated patterns which were then projected onto the paper cones...

Some thoughts about current state/trajectory of tech/software/ethics:

For ~30 years, I've been using, building and sharing open tools around algorithmic, generative & evolutionary design techniques, procedural generation, genetic algorithms/programming, machine learning... The incentives and potentials I saw (and still see!) in these areas/approaches are entirely orthogonal to what is called "generative AI" these days (saving that for a future post) and more importantly contrary to how that tech is being used...

Like many others, I'm desperately trying to keep a positive & balanced mind (also in terms of my own practice as an indie developer/researcher & artist), but I think it says a lot (in multiple ways) about the current state of tech/software/ethics, if the people/voices most critical and outspoken about the current/recent trajectories & decisions are (yet again[1]) the actual practitioners/experts of the field, often with decades of experiences... At the very least the issues raised should give some pause to people in politics/policy, academia/education, media and finance, i.e. all groups with much more direct control & responsibility, yet which are relatively silent in terms of critical voices/reflections and instead largely keep boosting and jumping on the AI hype train... I think I understand (though not agree with) many (self-serving) drivers of this "ignorance", but I've never seen this level of widespread uncritical technology adoption before in my life, especially the bewildering amount of willful ignorance of people who are (or should be) more informed, their active downplaying and rationalisations of multiple glaring systematic train wrecks (aka "jackpot") coming our way (are already here!), incl. climate, water, human rights violations, disinformation, politics/democracy, surveillance, unemployment, health/healthcare etc., and on a different level, pretty important issues like loss of "personal computing", of access (and accessibility!) and individual control of computing & information resources — all of which are massively accelerated by this in(s)ane drive for AI-generated profits...

What's the point of the above named societal institutions if none of them actually want to critically engage with these developments, before their window of opportunity closes?

(Sorry in advance, just a braindump, not gonna be able to reply to comments in the next few days...)
