pathfinder VS Skia

https://github.com/coconut-xr/apfel-kruemel works today, I only know about battery-optimized software in the context of games though.

https://felt.com/blog/svg-to-canvas-part-2-building-interact... and https://github.com/servo/pathfinder/ might also be of interest.

Parts of Servo to enable the use of the GPU for compositing layers were merged into Firefox years ago.

It's a shame that Patrick Walton didn't get a chance to finish his work on the Pathfinder GPU renderer.

>Pathfinder 3 is a fast, practical, GPU-based rasterizer for fonts and vector graphics using OpenGL 3.0+, OpenGL ES 3.0+, WebGL 2, and Metal.

It uses too much CPU and performance leaves much to be desired compared to Chromium. They were going to use Pathfinder in Firefox to solve this problem, but since Pathfinder is discontinued due to the massive layoffs at Mozilla, the project was abandoned. And they need a replacement IMO.

I am not an expert in the area, just somebody who read up on it after realizing desktop in VR does not work out for me (and usually low res is not a problem).

I think something like https://github.com/servo/pathfinder (newer) and as you mentioned SDF (older) are the latest approaches.

This is exciting! And, by the way, are you planning to implement something similar to Servo's Pathfinder in Firefox?

Also on my list was pathfinder. There the documented crate is vastly different from https://github.com/servo/pathfinder which looks much more promising – it comes with a few examples, some of wihch might help me get started, maybe?

Have you checked out the Pathfinder library?

Don't forget gpu-based text rendering (e.g. #1, #2, #3). It's still in its infant stages, and seems to be mostly untouched over the past 5 years, but I suspect it will become the preferred method for rendering text later.

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.
