mt-dom VS pathfinder

I don't have a writeup about it, but this is the specific commit of the new diffing algorithm

Under the hood, sauron uses mt-dom crate. The diffing algorithm in mt-dom has been extensively overhauled to work on all edge-case while allowing a much faster traversal for the generated patches.

It is using a new implementation of virtual DOM called mt-dom, which differs from most common implementation of virtual DOM. Most common virtual DOM implementation used in elm (or perhaps maybe react) is using NodeIdx (a usize) which force you to traverse each and every element that appear before the NodeIdx, just so you can patch the target element.

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.
