I wrote a post about my brief journey with #WebGPU, its inception and base concepts coming from #WebGL, and my attempt at abstracting parts of the API for a 3D engine.

@splitpoly [email protected] is updated to remove the old export. But actually the file itself is not used, as the worker code is inlined from `await fetch(`${transcoderPath}basis-worker.js`)`.

Every 20 seconds, a new Spirit Plant blooms—composed of 4 traditional Polish herbs and an ever-shifting palette of colours.
In just the first 3 days of Expo 2025, visitors have co-created thousands of unique digital plants at the Poland Pavilion. The result? An endlessly evolving garden of collective imagination.

Hello from Osaka! Visiting @expo2025_japan with @dmnsgn to install our latest installation launching in April. 🌿🌼🌺

Can't wait to share more procedural nature like this parametric Sakura from a previous project.

Lygia Pape: founding member of Grupo Frente and co-founder of the Neo-Concrete Movement. Broke the artwork frame, the opposition between form and background. Talked about “the devouring of the culture of the other” all under a dictatorial regime.

@padenot @mattdesl In my lib for building codec strings, I have a test page for VideoEncoder.isConfigSupported: https://t.co/RSylvCiitO
Chrome seems to be "lying" saying it supports "AVC High Profile Level 6.2" (which I tested and got @mattdesl OpenH264 error). FF and Safari both report correctly.

[Damien Seguin @dmnsgn]

@mattdesl @padenot Encoding a 4096x4096 at High 5.2 in Safari works (with mp4-muxer in canvas-record) while failing in Chrome 125 because of the maximum frame size of 9437184 pixels.

Level 6.2 is also failing in Safari though.

Hiding complexity in #visualprogramming aka eating half the spaghetti 🍝

[Marcin Ignac @marcinignac]

Graph cleaning - a story, the end might surprise you.
So i'm working on a big project where the @nodes_io graph was getting unwieldily convoluted (541 nodes!) and decided to clean it up.
It took me 3 days but it was all nice and tidy. But where did all the connections go? It's not like the project got less complex (well ok i removed 15% of unused code).
In Nodes on most of our projects we use "links" (portals) that allow you to refer to value by name in different parts of the graph. So I hacked Nodes UI to display all the invisible connections. Heh. Turns out it's all still there! 😳

Is there an agreed upon Tetrahedron starting orientation and offset (using centroid, apex, ...) ?

Nothing is 100% intuitive –for real-world scenari– when trying to fit it in a unit bounding box.
