Vulkan Cookbook

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.

Destroying a pipeline

When a pipeline object is no longer needed and we are sure that it is not being used by the hardware in any of the submitted command buffers, we can safely destroy it.

How to do it...

  1. Take the handle of a logical device. Use it to initialize a variable of type VkDevice named logical_device.
  2. Take the handle of a pipeline object that should be destroyed. Store it in a variable of type VkPipeline named pipeline. Make sure it is not being referenced by any commands submitted to any of the available queues.
  3. Call vkDestroyPipeline( logical_device, pipeline, nullptr ) for which provide the logical_device and pipeline variables and a nullptr value.
  4. For safety reasons, assign a VK_NULL_HANDLE value to the pipeline variable.
