With everyone busily using LLMs + Blender/Three.js to make 3D models, I thought I'd try a different geometric representation. This dragon isn't a mesh, NeRF, 3DGS, or video model: it's 27kb of GLSL code (generated via LLM), defining a closed-form implicit surface. 🧵 [1/n]

☍ The Ouroboros as a function of the form. Under mathematical laws, lambda calculus, and space phase geometry, the Ouroboros principle is translated into self referential recursive cycle and fixed point closure, outlining a function operating on itself, expressed by the equation 𝒻(𝒻) = 𝒻. The formula simply yields the process where the output becomes input without escaping the system. This logic relies on distinctions that point back to the observer, creating a self-containing universe of rules. Systems theory uses the Ouroboros to describe feedback loops where not only the result regulates the hierarchical structure itself, but also signifies immutability and independence from external interference. In theoretical biology the Ouroboros is strictly related to the autopoiesis function of self procreation in which living networks preserve themselves through internal circular regeneration. 🔗 arxiv.org/html/2105.04418v1

My guess: the big differentiator in modern software development will not be "taste", but sustained attention. Most software built quickly with AI will follow an "easy come, easy go" pattern and be abandoned shortly after announcement.

Most interesting printer you can build right now. Hello World written across a human hair (56μm). Motion system is driven by M3 threaded rods and some printed parts..

This is why I built my own image processing stack for my Pixel 10 Pro from scratch: blog.thepixelary.com/post/81…
A open secret is that all cameras are basically the same. Just look at the sensor. Leica SL2-S? IMX410 Sony a7 III? IMX410 Lumix S5II? IMX410 BMCC6k? IMX410 Same photosites…but they still manage different feels. The processing pipeline is where it gets interesting.

Of course, the #RepRapMicron can use itself to electro-etch the probe tips. Duh! This is a test using a 0.5mm hypodermic and the 10mA current in the #RepRap RAMPS board's Z Touch circuit. youtu.be/GB33HMUqppU

#インタラクション2026 にて、「DynaPin」を学部3年、一井がデモ発表します。 3Dプリンタのヘッドを用いてピンアレイを引き出し、サポートを構築します。 ユーザの介入を必要とすることなく、オブジェクトを制御してフィラメント使用量と造形時間を削減します。

Quick and dense 40 second recap of the RepRap micron project + many new developments on the current version. Very cool and built only with standard off-the-shelf parts. youtube.com/watch?v=dq_ZCf0-…

In engineering and art, geometry is often represented not as meshes or points, but as domain-specific structured *grammars*. In this work led by @milin_k_ and @jackzzhang, we investigated how to optimize these grammars ML-style with SGD. 4 simple rules make a huge difference!
Can we apply gradient descent to discrete changes? In our new #SIGGRAPHAsia paper, we show that gradient descent can work on shape grammars, as in CAD and procedural modeling, but only if the grammars are designed correctly!

Problem printing with 5 colors around the whole circle: cyan and yellow are both showing up on the outside of the print. Need to lower their ratios, so only black and white will end up on outside.

These bimetal heatbreaks are a blessing. Makes cooling so much easier, only a very weak fan needed.

Blender 5.0 will come with support for volume grids in #GeometryNodes. There is a new blog post about it: code.blender.org/2025/10/vol… #b3d #devfund

houdinitime! Got my Topology Optimization tool working for 3D shapes. I really like the results! Some really nice skeletal shapes emerge.
