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.

Simplifying Vulkan initialization and frame composition

Before jumping into this chapter, let's learn how to generalize Vulkan application initialization for all of our remaining demos and how to extract common parts of the frame composition code.

How to do it...

The Graphics Library Framework (GLFW) window creation and Vulkan rendering surface initialization are performed in the initVulkanApp function. Let's take a closer look:

  1. A Resolution structure can be passed as an optional parameter:
    struct Resolution {
      uint32_t width  = 0;
      uint32_t height = 0;
    };
    GLFWwindow* initVulkanApp(  int width, int height,  Resolution* outResolution = nullptr)
    {
  2. In our examples, we always use the glslang compiler and the Vector-Optimized Library of Kernels (VOLK) library. If anything goes wrong with initialization, we terminate the application:
      glslang_initialize_process();
      volkInitialize();
     ...
