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 fence

Fences, opposite to semaphores, are used to synchronize an application with commands submitted to the graphics hardware. They inform the application when the processing of a submitted work has been finished. But before we can use fences, we need to create them.

How to do it...

  1. Take the created logical device and use its handle to initialize a variable of type VkDevice named logical_device.
  2. Create a variable of type VkFenceCreateInfo named fence_create_info. Use the following values to initialize its members:
    • nullptr value for pNext
    • For flags use a 0 value if a created fence should be un-signaled, or a VK_FENCE_CREATE_SIGNALED_BIT value if a created fence should be signaled
  3. Create a variable...
