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!

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!

Amtrak might be really nice for this! Not sure if a loaner bike case would change the math, but my case (EVOC) is otherwise just sitting in a Gowanus CubeSmart.

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.

There's currently a (small) missing piece on the three.js WebGPURenderer side to use spark.js textures efficiently — details in github.com/mrdoob/three....

Don McCurdy @donmccurdy.com · Aug 7

This creates new options to consider when generating textures on the fly, as well, where GPU texture compression would not have been an option before.

(Note: Spark.js is free for non-commercial use, with a very fair one-time fee for indie and larger applications).

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.

I’m excited to announce the release of Spark 1.3 and the launch of spark.js, our new JavaScript API for real-time GPU texture compression on the web.

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!

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😄

importantly but not obviously, “HDR” formats (like the latest PNG version) are meant for “images for display” and not floating-point data, two different things

Great comparison of modern floating-point image formats including OpenEXR, JPEG-XL, and custom encodings:

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.
