Usages for vkCreateHeadlessSurfaceEXT
PS. I have tried to use vulkan-wsi-layer (https://gitlab.freedesktop.org/mesa/vulkan-wsi-layer) to support the VK_EXT_headless_surface, and use sample in https://github.com/SaschaWillems/Vulkan to builed a headless version triange. However, it failed at acquireNextImage from the swapchain.
Samples in https://github.com/SaschaWillems/Vulkan have shown how to use vkCreateHeadlessSurfaceEXT. But these headless samples crash at acquireNextImage from the swapchain. Now I guess the problem lies in the vulkan-wsi-layer.

Proper way to access a read-only texture that has no sampler from an hlsl compute shader?
BTW, this problem can be reproduced as described below: - clone https://github.com/SaschaWillems/Vulkan.git - build the project and run it with arguments : -v - s hlsl to enable the validation layer and to use hlsl code - run ComputeShader project. The following validation error "Type mismatch on descriptor slot ..." will be shown in the console. - to fix it, as suggested above, you can replace the 3rd line of emboss.comp, sharpen.comp, and edgedetect.comp from: Texture2D inputImage : register(t0); //Creates validation errors to RWTexture2D inputImage : register(u0); //no validation errors (you'll then need to recompile the shaders to spv with a proper hlsl compiler such as Microsoft dxc)

Recommendations on how to start a small Vulkan project
Another way I saw some projects start was by using example base classes (either Sascha Willems' implementations or the framework used by Khronos Samples).

I've been working on a real-time ray tracing renderer
It's not a tutorial but I'd recommend Sascha Willems examples. A good next step could be adding models and shadows (see https://github.com/SaschaWillems/Vulkan/tree/master/examples/raytracingshadows). It's a single file but you can easily understand what each function does.
-
Add a second texture to Sascha Willems glftLoading app
Exactly as u/aerorang said. I recommend comparing your linked example with Sascha's gtTF Scene rendering example where he adds a normal map along with the base albedo texture. He also marked important parts of the code with the POI keyword, so you can search for them in the code.

With GPT-4, as a Software Engineer, this time I'm actually scared
Second, you need to learn the basics of Vulkan API, such as how to create instances, devices, queues, swapchains, command buffers, pipelines, shaders, etc. You can find some useful tutorials and examples on https://vulkan-tutorial.com/ , https://vkguide.dev/ , https://github.com/SaschaWillems/Vulkan34, etc.
- Greetings. I went through the Vulkan tutorial, but I'm really stuck going beyond this point. Any word?

Hey Rustaceans! Got a question? Ask here (16/2023)!
There is also [Vulkano](https://github.com/vulkano-rs/vulkano). It has a safe high level api and lower level layers, all the way down to [ash](https://github.com/ash-rs/ash) which is more or less raw vulkan. It's more explicit and verbose than [wgpu](https://github.com/gfx-rs/wgpu) though, so maybe try wgpu first and see how you like it.

How to learn writing a Wayland compositor?
Understand Wayland concepts: Familiarize yourself with the basic concepts and principles of Wayland. This will help you gain a solid understanding of how the system works. You can refer to the official Wayland documentation (https://wayland.freedesktop.org/docs/html/) and the Wayland book (https://wayland-book.com/). Learn Rust: If you're not already proficient in Rust, take some time to learn the language. The Rust Book (https://doc.rust-lang.org/book/) is a great place to start. Study existing Wayland compositors: Since you mentioned Anvil and smallvil, you can study their source code to gain insights into how they're designed and implemented. Try to understand the structure and how different components interact with each other. Dive into Smithay: Smithay (https://github.com/Smithay/smithay) is a Rust library for building Wayland compositors. Familiarize yourself with the library and its components. You can start by studying the provided examples and reading the API documentation. Learn graphics programming: Since you're interested in graphics effects, you'll need to learn about graphics programming concepts, such as shaders, framebuffers, and texturing. Vulkan (https://www.vulkan.org/) is a popular graphics API that you can use with Rust. Check out the following resources to learn more about Vulkan and graphics programming in Rust: Vulkan Tutorial (https://vulkan-tutorial.com/) gfx-rs (https://github.com/gfx-rs/gfx), a Rust graphics library Vulkano (https://github.com/vulkano-rs/vulkano), a safe, pure-Rust wrapper around the Vulkan API Start small: Break down the compositor project into smaller, manageable tasks. Begin by implementing basic functionality, like setting up a window and drawing simple shapes. Gradually add more features, such as input handling and window management. Ask for help: Join the Wayland and Rust communities to ask questions and seek advice. You can find them on forums, mailing lists, and chat platforms like Discord or IRC. The Wayland mailing list (https://lists.freedesktop.org/mailman/listinfo/wayland-devel) and the Rust programming subreddit (https://www.reddit.com/r/rust/) are good places to start. Iterate and experiment: As you progress, keep experimenting with different graphics effects and shaders. Try to implement the features you're interested in, such as blur, window previews, and window switching.

Is C++ still the language when entering 3D programming in 2023?
Something like vulkano in Rust or zig-gamedev in zig might be a much more enjoyable approach: They're similarly bare metal languages but have a lot of advantages over C++ (borrow checker's safety, simpler syntax). However, they're not commonly used by big studios.

A 2D Pixel Physics Simulator with Cellular Automata written in Rust
I use the awesome Vulkano for rendering and computation, and Rapier for simple physics. Contour is used for the initial shapes, but rapier forms the physics colliders from it. Hecs is used as well. And you might recognize Egui as gui :). I gotta say, I'm starting to be pretty happy with the rust ecosystem overall.

What do the "| |" characters do?
As recently seen in: https://github.com/vulkano-rs/vulkano/blob/master/examples/src/bin/triangle.rs several times but I've seen them arround several other times also.
-
Crate the implements Vulkano/Vulkan?
Vulkano's website is terrible, yeah, and I'm not really encouraging you to use it, but fyi, the updated examples from their repo are… up-to-date. And they're exceptionally well-commented. So if you run out of options (which I have), take a look at the most recent triangle.rs.

Hey Rustaceans! Got an easy question? Ask here (43/2021)!
There's a few ways to do it. The low-level method is to write a HLSL shader then use something like vulkan to run it (vulkano example). If you want a 100% rust method, then wgpu and rust-gpu exists to let you define your shaders directly in rust while they handle more of the boilerplate.
