What Hacker News says
5 sourcesAnd a self-followup: I wrote https://github.com/linebender/piet-gpu/issues/49 to track this in piet-gpu.
In Ruffle – A Flash Player emulator written in RustIt looks like the main fruit of this is piet-gpu[1]. How close would you say it is to stable? And how complete a realisation of the concepts put forth in the OP? I'm currently working on a ui library, and evaluating alternatives for hw acceleration. The whole library wants to be in c, so I would want to rewrite the library by release-time to use it, but don't want to waste time doing that now if it's still really volatile.

In Fast 2D Rendering on GPUFollowup: I did a very rough prototype on my current Vulkan runner; all the good stuff is in the prefix.comp kernel code. It's not doing the fancy stuff, in particular it doesn't parallelize the lookback code, so that ends up taking a bunch of time. But it does give an example of how to use the Vulkan memory model, for which I've seen very little in the way of published material.
If anyone is interested in tuning this and doing a performance comparison, please get in touch. It'd make a good blog post, I think, but already the time I've spent on it is a distraction from the renderer.
