Vulcan, Go, and A Triangle, Part 7

In this part, I am going to add the the swapchain. My application will eventually take one of these swap chain images and draw to it, but that will be closer to the end of this tutorial.

This part follows closely with Drawing a triangle / Presentation / Image Views. I've opted to keep swapchain a single word, regardless of my spell checker; this is mostly because Vulkan treats it as one word in the API. So expect to see Swapchain where the Vulkan Tutorial would have written SwapChain.

Vulcan, Go, and A Triangle, Part 6

In this part we are going to add support for required device layers and extensions before creating a logical device. The logical device creation process is similar to the instance creation process. Instead of telling Vulkan about our application, we will be telling Vulkan about our device requirements.

This part follows closely with the Vulkan Tutorial. I do push the required extensions checks into the device selection function, but otherwise the steps are similar to Drawing a triangle / Setup / Logical device and queues.

Vulcan, Go, and A Triangle, Part 5

In this part I am going to create an object for keeping track of our physical device, enumerate over physical devices, and select a physical device for our application.

I deviate from the vulkan tutorial here a little bit because I wanted to encapsulate physical device related functionality in a specific class. This will become more useful later when dealing with memory buffers. I also create the surface in a different order.

This part relates to Drawing a triangle / Setup / Physical devices and queue families in the original tutorial.

Vulcan, Go, and A Triangle, Part 4

In this part of the tutorial, I'm going to inspect what extensions and layers are available for an instance. The call to vk.CreateInstance can result in vk.ErrorLayerNotPresent or vk.ErrorExtensionNotPresent according to the Vulkan spec. By inspecting the available options and checking if my required options are supported, I can provide a more debuggable error response.

Following the Vulkan Tutorial, I implemented the necessary functions to enumerate over available layers and extensions before calling CreateInstance. This part relates to Drawing a triangle / Setup / Instance / Checking for extension support in the original tutorial.

Vulcan, Go, and A Triangle, Part 3

In this part of the tutorial, we are going to initialize a vulkan instance. The vulkan instance is the connection between your application and the Vulkan framework. It allows the application to enumerate physical devices and supported functionality.

This part relates to Drawing a triangle / Setup / Instance in the original tutorial.

Vulcan, Go, and A Triangle, Part 2

In the last part, we started with adding dependencies, helper functions and the basic skeleton. In this part we are going to start expanding on setup(), cleanup(), and mainLoop().

Each part going forward will end with code that should build and run, although in many cases there will not be a visible output.

Part 2 roughly translates to the second half of Drawing a triangle / Setup / Base code.

Vulcan, Go, and A Triangle, Part 1

This tutorial follows my personal execution of the Vulkan tutorial, with the distinction of being in Go instead of C++.

I started this effort because Go is my preferred programming language and I was interested in understanding more about the modern landscape of GPU programing. While I was able to find a Vulkan tutorial translated for Rust, I could not find an existing one for Go.

While my exploration of Vulkan follows the general approach of the Vulkan Tutorial, I have done certain steps out of order and try to leverage Go idioms where I can. I also tried to write the code so that most steps start with pseudo-code comments which eventually get expanded into code-blocks.
