femtovg VS pathfinder

The problem with femtovg currently is, that it's based on OpenGL. There is a fork for wgpu already, but it's not up to date with master and I'm not sure how difficult merging will be.

You guys should also check out the femtovg project, a 2D rendering API that sixty fps relies on.

It's a decent starting point for trying to build your own toolkit.

I have recently added a wgpu backend but for now it lives in my fork https://github.com/adamnemecek/femtovg

run the demo with `cargo run --example wgpu_demo --release`.

It's not a GUI framework but I'm involved with this project called femtovg, it's a Rust nanovg port. I've recently added a wgpu backend. Run the demo with cargo run --example wgpu_demo --release. Some people have been using it for their own UIs, e.g. tuix. I think that you should consider rolling your own GUI toolkit, it's not that bad and you'll appreciate the control.

I have been recently rolling my own Rust GUI framework using this rendering crate I’m invovled with https://github.com/femtovg/femtovg and I’m pretty happy with it.

I recently added a wgpu backend https://github.com/adamnemecek/femtovg.

Combine that with the Flutter layout (check out the Druid implementation), and you have a GUI framework.

I added a wgpu backend not too long ago, it’s in my fork for now femtovg.

SixtyFPS is a project started by Simon Hausmann and Olivier Goffart who previously worked on Qt at Trolltech.

SixtyFPS is the first project with a company behind it which uses femtovg, a Rust nanovg port. https://github.com/femtovg/femtovg.

Recently, we've added an experimental wgpu backend which is for now in my fork of the project https://github.com/adamnemecek/femtovg

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.
