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 Vulkan shader modules

The Vulkan API consumes shaders in the form of compiled SPIR-V binaries. In the Compiling Vulkan shaders at runtime recipe, we learned how to compile shaders from source code to SPIR-V using the open source glslang compiler from Khronos. In this recipe, we will learn how to use these binaries in Vulkan.

Getting ready

We recommend reading the Compiling Vulkan shaders at runtime recipe before proceeding.

How to do it...

  1. Let's declare a structure that will hold a SPIR-V binary and its corresponding shader module object:
    struct ShaderModule {
      std::vector<unsigned int> SPIRV;
      VkShaderModule shaderModule;
    };
  2. The following function will compile a shader that's been loaded from a file using glslang and upload the resulting SPIR-V binary to Vulkan:
    VkResult createShaderModule(  VkDevice device, ShaderModule* sm,  const char* fileName)
    {
      if (!compileShaderFile(fileName...
