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.

Integrating EasyProfiler and Optick into C++ applications

In Chapter 2, Using Essential Libraries, we learned how to link our projects with EasyProfiler and Optick, and covered the basic functionality of these profiling libraries. In real-world applications, it is often beneficial to be able to quickly change profiling backends at will due to changes in requirements or to use unique features of different profiling libraries. In this recipe, we will show how to make a minimalistic wrapper on top of EasyProfiler and Optick to allow seamless switching between them using only CMake build options.

Getting ready

The complete source code of the demo application for this recipe is located in Chapter4/VK01_DemoApp.

How to do it...

The demo application, as well as some parts of our Vulkan rendering code, is augmented with calls to profiling functions. Instead of calling EasyProfiler or Optick directly, we have created a set of macros, one of which is picked based on compiler options...
