A pretty wild debugging story:

When updating Dawn (Chrome's WebGPU lib), I saw a +50% jump in GPU timings for most/all of my GPU timers (measuring draws, dispatches, etc.).

I bisected Dawn's commit history to find the commit where the perf regression happened, and it ...

initializing a MacOS native `NSImage` from png data may crash your application (via SIGBUS) if you happen to have a libpng.dylib on your machine that it doesn't like.

TIL: Fibonacci lattice sphere sampling.

Feels like magic! Third column in the picture below:

I think it worked out :)

Not 100% sure the SH is all correct, but quick checks looked promising. Best I add some debug options to the ui so I can easier compare "real-sky" with "SH sky"

Also, really need some shadow casting and anti-aliasing 😊

Said atmosphere is very much in progress, a half-done implementation of Sébastien Hillaire's "A Scalable and Production Ready
Sky and Atmosphere Rendering Technique". Plus some place-holder heightmap

Quick and dirty sphere sampling test. Very happy how quick this is to hack in Python (and @rerun.io , okay I'm obviously biased)

Plan is to use this for computing Spherical Harmonics from sky for my pet project :)

I finally ran more than 10km for the first time today \o/

Apparently, key to success it to run off in a random direction and have no idea where you're going. I'm sure there's a deeper life lesson in this somewhere 😁

actually a better idea might be to blur the mask target from which the SDF is generated - that way the outlines should get rounder as they are on the reference

I wonder if it gets closer when you slightly blur the SDF, maybe it gets closer then? 🤔

Unless Grace answers here directly you could always try attaching RenderDoc to find out how it was done :)

After many years of being active in wgpu that's somehow my first Naga contribution :3

Lotsa great stuff landed again in the #wgpu release earlier this week :)

wgpu-profiler (crates.io/crates/wgpu-...) and my minifb interop example (github.com/Wumpf/minifb...) are now updated as well to wgpu 24 🎉

I'm soooo proud of past-self right now 😍: digging up some micro controller project for the first time in 2.5 years (oh. times flies :/) and found that I actually documented what I did there, making it quite easy to get started again 🤯

This release we tried something new and put explainer videos into the release notes

We implemented undo in @rerun.io by storing the viewer state in the same type of in-memory database we use for the recorded data. Have a look (sound on!)

World grid for our 3D views is coming along nicely!

Once a quarter, we get the entire Rerun team together.

We spent a cold week in Stockholm planning our 2025. Our remote model gives us access to an incredible global talent pool, but these in-person meetups are the secret ingredient that helps us align, solve problems, and load up on energy!

Release 0.20.0 - Map view & native H.264 video support · rerun-io/rerun Rerun is an easy-to-use visualization toolbox for multimodal and temporal data. Try it live at https://rerun.io/viewer. Python: pip install rerun-sdk Rust: cargo add rerun and cargo install rerun-...

At work we recently released 0.20 of our multimodal visualization tool.
Had limited involvement into the new map view but ended up spicing up the example featured in the video which was a lot of fun. Really drove home to me what those modes in multimodal are all about 🙃

Hola graphics people! ❤️

I've been meaning to do some write-ups that are hopefully useful, so this first one is about my approach to Order-Independent Transparency.

Looks like this place is waking up. Let's give it a go!

Hi! I'm Andreas! I'm a developer at #rerun (rerun.io) and a co-maintainer of #wgpu, an open source graphics library.

I love building software! If there's any red thread to it than that it's usually for other engineers 😄
