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 multisample state

Multisampling is a process that eliminates jagged edges of drawn primitives. In other words, it allows us to anti-alias polygons, lines and points. We define how multisampling is performed (and if at all) through a multisample state.

How to do it...

  1. Create a variable of type VkPipelineMultisampleStateCreateInfo named multisample_state_create_info. Use the following values to initialize its members:
    • VK_STRUCTURE_TYPE_PIPELINE_MULTISAMPLE_STATE_CREATE_INFO value for sType
    • nullptr value for pNext
    • 0 value for flags
    • The number of samples generated per pixel for rasterizationSamples
    • A true value if per sample shading should be enabled (only if sampleRateShading feature is enabled) or false otherwise for sampleShadingEnable
    • A minimum...
