The Modern Vulkan Cookbook

Overview of this book

Vulkan is a graphics API that gives the program total control of the GPU, allowing the GPU to be used to its full potential. This cookbook will uncover useful techniques for emerging new technologies, such as hybrid rendering, extended reality – mixed reality (MR), augmented reality (AR), virtual reality (VR) – and GPU-driven rendering, and even features a dedicated chapter to help you debug and profile your graphics applications with tips and tricks tested in real-world scenarios. The book starts by explaining basic Vulkan concepts while guiding you through the implementation of a basic graphics engine. The building blocks presented in the first few chapters will then help you implement more advanced techniques and algorithms, while getting you acquainted with the inner workings of Vulkan. Gradually, you’ll discover how Vulkan can be used to build hybrid renderers as well as leveraged for the future of graphics with AR/VR/MR. Moreover, you’ll gain an understanding of how it can be debugged or measured for performance. By the end of this book, you’ll be well versed in how to use Vulkan to write graphics applications and how graphics algorithms are implemented using Vulkan.

Retrieving the queue object handle

Once the logical device has been created, we need to obtain the handle to queues. That is accomplished with the vkGetDeviceQueue function. This handle will be used to submit command buffers for processing on the GPU.

In this recipe, you will learn how to obtain the handle to a Vulkan queue.

Getting ready

In the repository, all queues are retrieved and stored by the VulkanCore::Context class. That class maintains a list for each type of queue: graphics, compute, transfer, and sparse, along with a special queue for presentation.

How to do it…

To retrieve the handle to a queue, just call the vkGetDeviceQueue function with the queue family index and the queue index:

VkQueue queue{VK_NULL_HANDLE};
uint32_t queueFamilyIndex; // valid queue family
vkGetDeviceQueue(device, queueFamilyIndex, 0, &queue);

Knowing which queue families are available is not enough. Once we determine which queues are available and the queues we need...
