rust-skia VS blitz

The only example that shedded some light on the integration was gtk4 + femtovg. So I mimicked the example, using gtk4-rs and Skia's rust bindings. I had some code similar to the following inside a subclass of GLArea to setup Skia's DirectContext, but it failed:

Checkout rust-skia.

Skia (https://github.com/rust-skia/rust-skia) which I think does a mix of software and gpu rendering

I‘d probably look into Skia first, it also drives Flutter. https://github.com/rust-skia/rust-skia

I have been looking around for a suitable vector graphics library to use. My short list is: skia-safe, skulpin, nannou, and cairo.

Flutter uses skia which implements a common API for all these GPU rendering backends. Maybe rust-skia is a good fit for your needs, but be prepared to lose lot of the time you saved by using a single codebase into coding your common UI framework :P

Have you talked to the Dioxus people recently?

They're working on a project called Dioxus Blitz; from what I'm told, they're trying to implement a minimal browser target, that provides some basic DOM-like features and renders with wgpu.

It's not exactly what you're hoping for, but you might find common ground.

(Also, the Linebender project is working on Masonry, with FFI as a medium-term goal.)

Your proposal sounds very similar to what the Dioxus folks are doing on Blitz, which is using HTML/CSS as the languages but doing native rendering. WebF seems much further along, and I know they've been exploring other rendering engines, so it may be an interesting conversation for you to have with them.

Others have already mentioned inlyne and blitz, however given that you're interested in combining web UI with game/wgpu rendering you may be more interested in bevy_ui (and the higher level APIs like bevy_ui_dsl and belly that sit on top of this). Bevy UI is working on a HTML model and is specifically designed to integrate with Bevy's main game renderer and other infrastructure. It's worth noting that a 0.11 release of Bevy of due in next few days, and that UI is going to be a strong focus of the 0.12 release cycle: which should lead to significant development of bevy_ui, and either a doubling down on the "HTML-like UI" approach or a pivot to a new approach.

Here is an example: https://github.com/DioxusLabs/blitz/blob/master/examples/buttons.rs

There’s actually quite a lot of interesting work going on in that general space, has been in various forms for some years. A couple that immediately spring to mind:

• Azul <https://azul.rs/> builds on WebRender, as used in Firefox. I haven’t looked at it for a few years, but it looks to have grown quite interesting now.

• Blitz <https://github.com/DioxusLabs/blitz> is based on from-scratch implementations of CSS layout and rendering, and wgpu rendering. It’s not usable yet, but is a very interesting concept. If one happens to be familiar with React Native: it’s kinda like that, or React Native Web.

You may also be interested in https://github.com/DioxusLabs/blitz which aims to be a full HTML+CSS renderer on top of wgpu (but is currently not nearly as complete as inlyne).

If you are focused on performance we are working on a native renderer for Dioxus called Blitz. It is very incomplete right now, but in the future it will be much more performant than the current webview based approach.

There hasn't been too much progress on Blitz in the last few weeks (it will come), but there is now a new project Freya which is using a Dioxus frontend and rendering with Skia. That's currently using it's own layout system instead of Taffy though.

The main desktop renderer for Dioxus uses wry (the webview tauri uses internally), so the startup time will likely be similar. We are working on a native renderer called blitz which should improve this, but development is still early
