Trying to imagine feeling the need to weigh in defending billionaires here. Under Tim, Epic laid off ~20% of its employees earlier this year. Whatever you think about AI—people are actually afraid for their work and their security. Care about people; resist leaders who don't.

I'll be presenting at the Cesium Developer Conference June 8–10th, on: 3D Tiles, glTF, and visualizing geospatial data on the web with Cesium.js. Consider joining! :) Location: Philadelphia, PA, USA cesium.com/events/cesiu... #CesiumDevCon #WebGL #WebGPU #OpenSource

New Poimandres website! pmnd.rs By krispya (on GitHub). #threejs #webgl #webgpu

🎉 Applications for the Sovereign Tech Fellowship are officially open! What’s new? For the first time, community managers, and technical writers can apply alongside open source maintainers until April 6, 2026, to become Fellows.

@cwilso.bsky.social Hey Chris, wanted to drop a note to say thanks for your Web Audio writeups! I’ve been running into them a lot this past month. ❤️

“Surfel-based global illumination on the web, using three.js and WebGPU.” So much good stuff here by @juretriglav.bsky.social — demo! interactive illustrations! source code! A deep dive but clearly explained, fun, and worth the time. juretriglav.si/surfel-based...

Really worthwhile reading from @icastano.bsky.social! If you're building with WebGPU, spark.js gives you new choices for texture compression that weren't possible with WebGL. Also, I need to update my older blog post. 😅

three.js r182 was just released! 🎉 github.com/mrdoob/three.js/rel I contributed support for RG normal maps, enabling BC5 and EAC_RG normal map compression in both the WebGL and WebGPU renderers. #webgpu #webgl #threejs

A brand new website to celebrate 10 YEARS (!) of beautiful markdown documents with Markdeep: casual-effects.com/markdeep/ Same efficiency, 100% data privacy, and client-side processing. New agentic AI support, fancy CSS styles, and compatibility for a seamless document experience.

I built this little tool to optimize and re-export GLTF/GLB assets to GPU-compressed KTX2. It runs entirely client-side/in-browser. You can fiddle with the parameters, compare the before/after, and export to GLB. Try it here: gltf-optimizer.simondev.io #threejs #gamedev

I've joined the Cesium team, now part of Bentley Systems! Working with Patrick and others at Cesium over the years, on glTF and 3D Tiles, has always been a great joy. More work in open source and open standards ahead. ☺️ cesium.com/blog/2025/11...

i wrote everything that i've been kind of nervous to write about @val.town: here's how things have been going the last three years, and read to the end for how we're hiring for two people macwright.com/2025/11/11/v...

Version 0.9.2 of three-mesh-bvh is out now and brings support for raycasting & distance queries using WebGPU compute shaders! This is the first step towards WebGPU path tracing & other compute-shader features 🚀✨ #threejs #webgpu #javascript

recommitted to @opensourcepledge.com at @val.town for 2025! very pumped to support projects like zod, fastify, codemirror, unified, and esm.sh with real 💸 as well as positive vibes. blog.val.town/oss-pledge

Job update: after nearly 8 years of open source I'm excited to go independent to work on consulting & OSS dev. More details to come, but feel free to reach out about collaborations or how you can support my work! #threejs #javascript #webgl #gis #cad

i know we're all tired of the DHH stuff, but… if you've written this off as a normal political disagreement or just been too overwhelmed to look into it (understandable!), i really think you should take five minutes to read firsthand exactly what these people are defending with their whole chests:

Writeup by @icastano.bsky.social — very worthwhile comparisons for anyone building texture-heavy applications in WebGPU, with a case study and integration in @threejs.org!

Anyone want to test #webgpu page where I'm testing performance of rendering many points, using GPU vs compute shader? aras-p.info/files/temp/w... I'd like to know GPU times for each of 5 buttons, with&without compute shader checkbox, and the GPU model. My own numbers at the bottom of the page.
