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.

Selecting a number of swapchain images

When an application wants to render into a swapchain image, it must acquire it from the presentation engine. An application can acquire more images; we are not limited to just one image at a time. But the number of images that are available (unused by the presentation engine at a given time) depends on the specified presentation mode, the application's current situation (rendering/presenting history), and the number of images--when we create a swapchain, we must specify the (minimal) number of images that should be created.

How to do it...

  1. Acquire the capabilities of a presentation surface (refer to the Getting capabilities of a presentation surface recipe). Store them in a variable of type VkSurfaceCapabilitiesKHR named...
