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

Anyone using #Obsidian / #ObsidianMD for photo management? Like Adobe Lightroom, minus the editing features? 1/

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've used Arc (web browser) for the past few years, and it's good... but for software as security-critical as a browser, I don't love that it's really a side project for a VC-backed AI startup at this point. Writing on the wall and all that. So... 1/

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

What's the minimum feasible number transitive dependencies for maintaining and publishing a small JavaScript library with types? Assume: unit tests, bundle .ts sources to .js and .d.ts, and maybe shared lint-and-format settings.

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!

a classic double-cross

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.

meshoptimizer v0.25 is out! Featuring new simplification function that optimizes positions and attributes for appearance, experimental permissive mode to simplify faceted regions with selective seam preservation, regularization option for improved tessellation quality and deformation, multiple ...

Small update for my collection of tiny 40x40px KTX2 samples: RGB9E5 and R11G11B10. github.com/donmccurdy/K...

Very big announcement from @icastano.bsky.social for WebGPU apps! Spark.js means you can send small file formats over the network (WebP, AVIF, ...) and compress to GPU texture formats like ETC2, BCn, or ASTC near-instantly using WebGPU — at runtime. #threejs #webgpu #webgl

spark.js wraps a subset of these codecs with a simple and lightweight API. Making it easy to use modern image formats for storage and delivery and transcode them at runtime to more efficient GPU formats. This is literally free bandwidth!

our 3D compression tool is out now! the dream of making entire assets smaller than a single image is real; we've made entire multi-level, dozens-of-models games in under 7 MB entirely free and client side gltf-compressor.com

The interaction is finally ready! It was tricky to calibrate, but it now supports up to 6 people, reacting to full-body movement velocity. The more energetic your motion, the stronger the response. During my tests kids loved it. They had a blast jumping around nonstop😄

Great comparison of modern floating-point image formats including OpenEXR, JPEG-XL, and custom encodings: aras-p.info/blog/2025/07...

Rebooting an old proposal for three.js! Adding an AgX tone mapping option with a “look” (contrast, saturation, etc.) more similar to other three.js tone mappers. It's a compromise. Would love to add a color grading API, but “perfect is the enemy of good” and all that. github.com/mrdoob/three...

Hello #portfolioday. I'm Chris, an 3D artist & illustrator from the PNW. Lately I've been getting more serious about game development as well. sweaterparrot.com linktr.ee/sweaterparrot

meshoptimizer 0.24 is out! Featuring new meshlet builder for raytracing workloads, improvements to cluster partitioning, new functions for reindexing, simplification, clustering and coverage computation, many internal improvements and, of course, VS2013 support!

To make it work, I've written a new JavaScript wrapper for xatlas called "watlas". It's available now on npm!

Very excited about this feature by @toji.dev. New in glTF Transform v4.2: generate texture coordinates (“UV mappings”) for any glTF scene! UVs can be created per-primitive, or grouped for use with texture atlases. Documentation: gltf-transform.dev/modules/func...

The Rendering Engine Architecture Conference (REAC) conference talks from today aren't online yet, but it's such a fun — and free! — event. The Overwatch talk about global illumination was a highlight for me. More talks tomorrow, starting 8:00am PT: enginearchitecture.org

REAC 2025 is now live!! Sign up and enjoy the stellar talks now! Machine Games are sharing their lessons on getting to 60HZ while delivering great visual fidelity Program: enginearchitecture.org/2025.htm Register: tinyurl.com/register4rea... (And get immediately access to the conference stream)

Would web devs use this? - subscribe to highly anticipated features (like Temporal) - get notified when they land in a new browser / become Baseline - via email, bsky, GitHub, Slack, whatever

Fellow film tech nerds, today I'm launching a brand new demo debunking some common misconceptions about so-called "HDR" colorspace. Up now on my website. #NerdyFilmTechStuff www.yedlin.net/DebunkingHDR

I finally got around to redoing my website: sweaterparrot.com. Mostly the same stuff as before - the main difference is just that I rewrote it from scratch instead of using Adobe Portfolio (and as a result it loads quite a lot faster and the design is a bit cleaner).

"The thing you are supposed to be decentralizing is power." Wonderful work @bsky.app team!

I’ve been thinking about what alternatives (not replacements!) for the three.js glTF loader would look like … suppose you enforce that input files are preprocessed offline (known buffer layout, meshopt compression, baked light or bvh data, …) what can/should that enable?

Started working on a tile shadow system for threejs. Quickly hit the 16-texture limit when trying to layer in cascaded shadows and VSM, so I added depth texture array support (texture_depth_2d_array/sampler2DArrayShadow) and reworked the shadow nodes. Should be ready soon!

Go and support amazing libraries like gltf-transform if your projects depend on it! #threejs #webdev #webgl #r3f
