Overview of this book

OpenGL is a popular cross-language, cross-platform application programming interface (API) used for rendering 2D and 3D graphics, while Vulkan is a low-overhead, cross-platform 3D graphics API that targets high-performance applications. 3D Graphics Rendering Cookbook helps you learn about modern graphics rendering algorithms and techniques using C++ programming along with OpenGL and Vulkan APIs. The book begins by setting up a development environment and takes you through the steps involved in building a 3D rendering engine with the help of basic, yet self-contained, recipes. Each recipe will enable you to incrementally add features to your codebase and show you how to integrate different 3D rendering techniques and algorithms into one large project. You'll also get to grips with core techniques such as physically based rendering, image-based rendering, and CPU/GPU geometry culling, to name a few. As you advance, you'll explore common techniques and solutions that will help you to work with large datasets for 2D and 3D rendering. Finally, you'll discover how to apply optimization techniques to build performant and feature-rich graphics applications. By the end of this 3D rendering book, you'll have gained an improved understanding of best practices used in modern graphics APIs and be able to create fast and versatile 3D rendering frameworks.

Initializing compute shaders in Vulkan

Up until now, we used only graphics-capable command queues on a Vulkan device. This time, we have to find device queues that are also capable of GPGPU computations. In Vulkan, such queues allow execution of compute shaders, which can read from and write to buffers used in the graphics rendering pipeline. For example, in Chapter 10, Advanced Rendering Techniques and Optimizations, we will show how to implement a GPU frustum culling technique by modifying the indirect rendering buffer introduced in the Indirect rendering in Vulkan recipe from Chapter 5, Working with Geometry Data.

Getting ready

The first thing we need to do to start using compute shaders is to revisit the render device initialization covered in Chapter 3, Getting Started with OpenGL and Vulkan. Check out the Initializing Vulkan instances and graphical device recipe before moving forward.

How to do it...

We add the code to search for a compute-capable device queue and...
