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 a pipeline depth and stencil state

Usually, when we render a geometry, we want to mimic the way we see the world--objects further away are smaller, objects closer to us are larger and they cover the objects behind them (obscure our view). In modern 3D graphics, this last effect (objects further away being obscured by objects being nearer) is achieved through a depth test. The way in which a depth test is performed, is specified through a depth and stencil state of a graphics pipeline.

How to do it...

  1. Create a variable of type VkPipelineDepthStencilStateCreateInfo named depth_and_stencil_state_create_info. Use the following values to initialize its members:
    • VK_STRUCTURE_TYPE_PIPELINE_DEPTH_STENCIL_STATE_CREATE_INFO value for sType
    • nullptr value for pNext...
