rend3 VS femtovg

The WGPU people are still working through lock conflicts in that area. The idea with Vulkan land is that you should be able to load content while rendering is in progress. For that to be useful, all the layers above Vulkan also have to have their locking problems hammered out. Most open source game engines don't do that yet. Unreal Engine and Unity do, which is why you pay for them for your AAA title.

The big problem I have with bevy here is that they seem to be very much against bevy being reusable across the ecosystem. Every feature has to be bevyfied into an ECS thing. There's no way one can use bevy_input for input handling outside of bevy, or bevy_audio for audio, or bevy_render to get a 3d renderer like https://rend3.rs/. The Rust ecosystem would've been so much better off if bevy wasn't creating a walled garden and draining insane amounts of effort just for itself, but say instead used rend3 for its rendering, so that other efforts in rust gamedev didn't have to reimplement everything from scratch.

We have our own engine. There aren't really full engines available in the Rust ecosystem. Bevy attempts to fill this, but it's far from being feature complete. There's also https://fyrox.rs/, but that's also work in progress. There's also https://rend3.rs/ which is just a 3d renderer, so you'll need to build the rest of the engine yourself.

That's been fixed. It was one of those things where a complicated workaround for Rust's ownership rules, one that required maintaining internal consistency between multiple tables, was inconsistent.

Rend3 crashes The library's internal memory allocator for GPU objects is losing objects and panicking. This seems to be a race condition that comes up once you get past displaying static scenes and start having moving objects. Rend3 has one overworked main developer. If you're qualified to work on GPU-level stuff, which I am not, that project could use help.

I personally use Rend3, ability to use WGPU to make my own render effects, but I still get to build my own engine around it, although I'm waiting for the vertex-pulling branch to be merged before I really get going

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
