Overview of this book

Vulkan is the next generation graphics API released by the Khronos group. It is expected to be the successor to OpenGL and OpenGL ES, which it shares some similarities with such as its cross-platform capabilities, programmed pipeline stages, or nomenclature. Vulkan is a low-level API that gives developers much more control over the hardware, but also adds new responsibilities such as explicit memory and resources management. With it, though, Vulkan is expected to be much faster. This book is your guide to understanding Vulkan through a series of recipes. We start off by teaching you how to create instances in Vulkan and choose the device on which operations will be performed. You will then explore more complex topics such as command buffers, resources and memory management, pipelines, GLSL shaders, render passes, and more. Gradually, the book moves on to teach you advanced rendering techniques, how to draw 3D scenes, and how to improve the performance of your applications. By the end of the book, you will be familiar with the latest advanced techniques implemented with the Vulkan API, which can be used on a wide range of platforms.

Creating a command pool

Command pools are objects from which command buffers acquire their memory. Memory itself is allocated implicitly and dynamically, but without it command buffers wouldn't have any storage space to hold the recorded commands. That's why, before we can allocate command buffers, we first need to create a memory pool for them.

How to do it...

  1. Create a variable of type VkDevice named logical_device and initialize it with a handle of a created logical device.
  1. Take the index of one of the queue families requested for the logical device. Store this index in a variable of type uint32_t named queue_family.
  2. Create a variable of type VkCommandPoolCreateInfo named command_pool_create_info. Use the following values for the members of this variable...
