wgpu VS gdnative

When I started the project, the existing deno_webgpu crate didn't expose enough to make rendering directly to windows possible. An initial version of that support was added to mainline deno_webgpu recently (see https://github.com/gfx-rs/wgpu/pull/3265), but by then, my own denog_webgpu fork had more features. Hopefully I can at least start using mainline deno_webgpu one day.

There's raw bindings, once upon a time people worked on a safe wrapper but figures that kind of thing needs to be opinionated to a degree that you can just as well write an engine, or go right ahead and implement WebGPU and have something that also runs on DirectX, Metal, etc. It's what bevy uses as backend for its default renderer.

If you are just getting into graphics, also consider checking out wgpu https://github.com/gfx-rs/wgpu the Rust implementation of the WebGPU standard.

Conceptually it's the same as Vulkan it's just a lot less pain in the ass to work with.

Hello everyone, wasn't sure if this is a bug or if I am missing something here but for some reason the following buffer (that worked in wgpu 0.13.1): let some_buffer = device.create_buffer(&wgpu::BufferDescriptor { label: Some("Some Label"), size: (std::mem::size_of::()) as u64, usage: wgpu::BufferUsages::STORAGE | wgpu::BufferUsages::MAP_READ | wgpu::BufferUsages::COPY_DST, mapped_at_creation: false, }); no longer works after upgrading to wgpu 0.14.2 and the error message I receive is: Caused by: In Device::create_buffer note: label = `Some Label` `MAP` usage can only be combined with the opposite `COPY`, requested MAP_READ | COPY_DST | STORAGE This doesn't make sense, since MAP_READ is the opposite of COPY_DST (right?). Also, I saw that this error message is not a new addition in 0.14.2 (in this issue, where it made sense). What am I missing?

I created an issue about this, the solution (and explanation) for the problem can be found there.

https://wgpu.rs seems like the way to go

If all you're looking for is low-level rendering, I'd recommend using wgpu.

the "p5.js" of rust is definetelly nannou. but i wouldn't recommend it for something that is graphics heavy, nannou is great for visualizations, effects, animations and stuff, but for proper 3d rendering and stuff you should go to wgpu (which has a great walkthrough: https://sotrh.github.io/learn-wgpu/), or some opengl binding which there are many of: https://crates.io/keywords/opengl

There is wgpu, which is just graphics.

Also if you want to use this as an opportunity to learn Rust, take a look at godot-rust.

GDExtension is a platform, much like GDNative. It provides tools, but additional language bindings will still come from the community. For Godot Rust you can track the progress here: https://github.com/godot-rust/godot-rust/issues/824

For what its worth, you can write your scripting for godot in Rust with godot-rust. It's not perfect cause its fitting Rust into the Godot model, but it'll also give you a "best of both worlds" type of situation if you want to get up and running quick but also do the game logic in Rust.

There's godot-rust for writing Rust components for the Godot engine.

If you desire to use Godot, as having the editor and support, while wanting to use Rust for the logic, might wanna look into Godot Rust.

Current version of godot-rust uses type-state to declare Ref references "safe to use" once the user has asserted their safety, and to switch between shared/unique/thread-local ownership.

If you're willing to get your hands a little dirty, you can also use Rust anywhere that exposes a C API or allows you to dynamically load C ABI libraries, but then you have to work with ugly interface stuff. It's doable. Using Rust with Godot isn't too unreasonable through gdnative/godot-rust. No idea how that's going to change up with Godot 4, though.

That said, what you may want to keep an eye on are Rust bindings like: https://github.com/godot-rust/godot-rust

If you like Rust there are (immature) bindings for Unreal and Godot. Or you might like to use a pure Rust engine like Bevy, Fyrox etc.

For example, with https://godot-rust.github.io/
