rerun VS Skia

Maybe the folks at Rerun [1] know something about it? I imagine at least some of their customers are Rust robotics shops.

Full release notes: https://github.com/rerun-io/rerun/blob/main/CHANGELOG.md

No specific support for audio embeddings yet, though depending on you're specific use-case, you might be able to map your data to more generic primitives such a TimeSeriesScalar, LineStrips2D, BarChart, or Tensor.

We have an open issue for adding more support for audio-based projects -- if you have specific needs feel free to add a comment: https://github.com/rerun-io/rerun/issues/2852

https://github.com/rerun-io/rerun is such a great tool for creating interactive dashboards to look at real-time data. Curious if there are others looking for something like this and what the other use cases would be interesting. I have heard ideas like:

egui's lead author is using it for his computer vision startup.

To test the power draw, I conducted an unscientific experiment by circling the cursor over both a GTK4 app (GNOME Console) and an egui app (Rerun Viewer), while monitoring the CPU/GPU utilization and stabilized power draw with PowerTOP. The results indicated that when circling the cursor over the GTK4 app, the CPU/GPU usage was nearly negligible, and the stabilized power draw was around 13 W. In contrast, when circling the cursor over the egui app, the CPU/GPU usage was considerably higher, resulting in a stabilized power draw of around 21 W. This amounts to an increase of approximately 60%. Taking into account a power draw of around 10 W when doing nothing at all, the increase becomes roughly 260%. I also tried the same experiment with Iced, and while the increase was not as extreme, it still utilized resources when circling the cursor over a blank surface.

Actually, that's not entirely accurate. The lottie-web library itself doesn't support rendering to WebGL. However, there is a package called canvaskit-wasm that wraps Skia (a graphics engine) with WebAssembly (wasm). This package includes a module called skottie which supports rendering animations into a WebGL surface. However, there is a drawback with this approach: using wasm requires loading a relatively large package, and it's uncertain whether all features are supported correctly, as the official compatibility table that tracks lottie support on different platforms does not include skottie.

Skia is pretty great if you can get it running.

The imgs are mainly used by Tencent QQ and Baidu Tieba users. QQ and Tieba compress imgs by default, so the popular imgs (in China we call them "屌图" or "表情包") would be compressed million of times during the spreading, causing the super low quality. These APPs on Android are using Skia for image processing, which suffering from a legendary bug: result would be more green. The bug was fixed in 2016: https://github.com/google/skia/commit/c7d01d3e1d3621907c27b283fb7f8b6e177c629d

There’s also Skia by Google. Used by Android and Google Chrome.
