> Can you imagine rewriting a modern web browser engine to use GPU-accelerated text rendering? https://github.com/servo/pathfinder uses GPU compute shaders to do this, which has way better performance than trying to fit this task into the hardware 3D rendering pipeline (the SDF approach).

I understand the appeal of Rive. However, even if their renderer is open source now, their editor isn't and their free tier is quite limited. Have a look into supporting Ruffle/SWF content, Lottie, etc. Also, for a renderer there is one by Mozilla called Pathfinder: https://github.com/servo/pathfinder

https://github.com/coconut-xr/apfel-kruemel works today, I only know about battery-optimized software in the context of games and IoT though. https://felt.com/blog/svg-to-canvas-part-2-building-interact... and https://github.com/servo/pathfinder/ might be of interest.

Parts of Servo to enable the use of the GPU for compositing layers were merged into Firefox years ago. https://hacks.mozilla.org/2017/10/the-whole-web-at-maximum-f... 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. https://github.com/servo/pathfinder

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, so it is about font aliasing). Something like https://github.com/servo/pathfinder (newer) and as you mentioned SDF (older) are the latest approaches.

I've been looking for a hardware accelerated vector graphics library and I'm quite shocked that the only good cross-platform option is Google's Skia. Every other library (e.g. Cairo or NanoVG) is either not performant enough or simply no longer maintained. I got my hopes up when I found Pathfinder https://github.com/servo/pathfinder but it seems has been abandoned. What's the reason behind this? Text/vector rendering is needed pretty much everywhere, so why are so few options for a good vector graphics library?

Raph Linus has recently has his work posted on HN, which features GPU rasterization [1] Also, Pathfinder [2] has the ability to do most of its rasterization on the GPU. I read somewhere that an experimental renderer for Google’s Fuchsia (Spinel?) [3] also does this. 1: https://github.com/linebender/piet-gpu 2: https://github.com/servo/pathfinder 3: https://www.tdcommons.org/cgi/viewcontent.cgi?article=1580&c...

Have you checked out the Pathfinder library? https://github.com/servo/pathfinder

This demo UI (https://github.com/femtovg/femtovg/blob/master/assets/demo.p...) is the same one I've seen in the Pathfinder (https://github.com/servo/pathfinder) examples. Is it something common, like the tiger used to demo SVG libraries?

Indeed, however I think we might replace Go with any programming language and your comment will still make sense. Currently, web-browsers are the best have-it-all platforms, and outside web-technologies there isn't many good alternatives. We landed in 2020 and we don't have any complete, native-like, cross-platform GUI toolkit (if we skip Qt and GTK). In last years a lot projects have appeared, which were trying to compete in GUI toolkit market share. All of them had its scope limited, however they brought quite fresh look on declarative programming interface [0][1], superb 2D rendering pipeline [2][3], ease of embedding [4] and adaption to low-power devices [5] but none of them is "complete". Personally, I am amazed of the implementation of rxi/lite [6], which is just an app (C with Lua) based on SDL2 library. It uses 2x less RAM than s

> pretty, freetype-like font rendering is super expensive when you have a lot of text to show, and can't really be done (at least I have definitely not seen infinality-level beauty from the state of the art) on the GPU yet This is exactly what Pathfinder does. pcwalton is on this thread and is the main author of that. https://github.com/servo/pathfinder#features says: > Advanced font rendering. Pathfinder can render fonts with slight hinting and can perform subpixel antialiasing on LCD screens. It can do stem darkening/font dilation like macOS and FreeType in order to make text easier to read at small sizes. The library also has support for gamma correction.

any relation to the work currently being done here by pcwalton? https://github.com/servo/pathfinder/pull/350 hopefully you guys aren't doing identical work in parallel (no pun intended) :)

How cool! I remember Mozilla announced some work on improving text rendering under 3D transformations, do you think that could be integrated? https://github.com/servo/pathfinder
