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

I gave a talk on large-scale data visualization on the web at
the 3D on the web meetup last month at GDC, check it out
https://youtu.be/HzcFzCkt5aU?si=6pLmPO9JEPBfMQB1
to hear about what I'm up to with #WebGL #WebGPU #WebAssembly
#Jupyter and some challenges I'm working on that I'd love to chat about!

If you're interested in 3D on the web and in the bay area next week for GDC/GTC or just live there, come by the meetup on Wednesday https://www.khronos.org/events/3d-on-the-web-2025 ! There's a good line up of talks, I'll be talking about bringing scivis to the web w/ #WebGL / #WebGPU / #WASM

I've written a brief guide for profiling WebGPU commands with Xcode's Metal debugger. It's... not exactly easy, but it works! I've got several ideas for how to improve it in the future, too.

Also, if you know Xcode better than me (a very VERY low bar) then I'd be thrilled if you have any suggestions to make this process better!

Our paper on elevation-aware flood extent mapping brings topologically guided segmentation to the web for crowdsourced labeling. ML flood mapping models trained on these maps w/ our correction framework get similar quality as those w/ solely expert labels! PDF: https://www.willusher.io/publications/flood-annotation-pvis25/

Our new paper, Approximate Puzzlepiece Compositing, applies OIT to data-parallel rendering to efficiently render overlapping, jigsaw puzzle-like data distributions, without repartitioning or expensive compositing. It'll presented at Pacific Vis 2025, check it out: https://www.willusher.io/publications/apc-pvis25/ !

Do you want to learn path tracing? Two lectures that I held at TU Delft are on YouTube now! The 2nd is what I had in mind for part 3 of my PT workshop. No Shadertoy exercises this time, but an open source Vulkan path tracer 🥳.

Wojciech Jarosz has movedDec 3, 2024

Need to inspect an (#HDR / #OpenEXR) image on an iPad, iPhone, or a computer without a proper image viewer? HDRView’s latest beta seemingly now works in those cases. Just go to:

https://wkjarosz.github.io/hdrview/

And creating a home screen bookmark on iOS makes it almost feel like a real app.

Slang shading language and tooling is now a Khronos project (was an nvidia project for past umpteen years). This is exciting! GLSL seems to be frozen with no future, whereas Slang is not only actively developed, but also brings in a lot of language features that sound useful. Nice! https://shader-slang.com/blog/2024/11/20/theres-a-lot-going-on-with-slang/
There’s a lot going on with Slang!
