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.

Specifying dependencies between subpasses

When operations in a given subpass depend on the results of operations in one of the earlier subpasses in the same render pass, we need to specify subpass dependencies. This is also required if there are dependencies between operations recorded within a render pass and those performed before it, or between operations that are executed after a render pass and those performed within the render pass. It is also possible to define dependencies within a single subpass.

Defining subpass dependencies is similar to setting up memory barriers.

How to do it...

  1. Create a variable of type std::vector<VkSubpassDependency> named subpass_dependencies. For each dependency, add a new element to the subpass_dependencies vector and use...
