Vulkan Code Structure

As you have seen in the previous chapter, Vulkan is a very low-level API. This means that it is very verbose and requires a lot of code to get something done. In this chapter, we will take a look at the code structure of a Vulkan application and how to set up the Vulkan instance, device and all the other things that are required to get started.

As of now we have created a Vulkan instance, Selected a device and created a logical device. We have also created a surface and a window using the windows API.

Folder Structure

The folder structure of the project for this guide should be as follows:

├── src
│   └── main.cpp
│   └── vulkan
│       ├── Container.h
│       ├── Container.cpp
│       ├── Common.h
│       ├── Common.cpp
│       ├── Application.h
│       ├── Application.cpp
│       ├── SwapChain.h
│       ├── SwapChain.cpp
│       ├── Device.h
│       ├── Device.cpp
│       ├── Pipeline.h
│       ├── Pipeline.cpp
│       ├── Shader.h
│       ├── Shader.cpp

File	Description
main.cpp	The main entry point of the application.
Container.h	This will be where we will store a singleton that will contain all the vulkan objects.
Common.h	Contains common includes and macros.
Application.h	Contains the application class, used to create the window and the vulkan instance.
SwapChain.h	Contains the swapchain class, used to create the swapchain and the image views.
Device.h	Contains the device class, used to create the logical device and the command pool.
Pipeline.h	Contains the pipeline class, used to create the render pass and the graphics pipeline.
Shader.h	Contains the shader class, used to load the shaders into shader modules.

Some files we wont be using for a while, but they are included for completeness.
