▶Book Description
Although numerous languages are currently being used to develop games, C++ remains the standard for fabricating expert libraries and tool chains for game development. This book introduces you to the world of game development with C++.

C++ Game Development By Example starts by touching upon the basic concepts of math, programming, and computer graphics and creating a simple side-scrolling action 2D game. You'll build a solid foundation by studying basic game concepts such as creating game loops, rendering 2D game scenes using SFML, 2D sprite creation and animation, and collision detection. The book will help you advance to creating a 3D physics puzzle game using modern OpenGL and the Bullet physics engine. You'll understand the graphics pipeline, which entails creating 3D objects using vertex and index buffers and rendering them to the scene using vertex and fragment shaders. Finally, you'll create a basic project using the Vulkan library that'll help you get to grips with creating swap chains, image views, render passes, and frame buffers for building high-performance graphics in your games.

By the end of this book, you'll be ready with 3 compelling projects created with SFML, the Vulkan API, and OpenGL, and you'll be able take your game and graphics programming skills to the next level.

▶What You Will Learn
- Understand shaders and how to write a basic vertex and fragment shader
- Build a Visual Studio project and add SFML to it
- Discover how to create sprite animations and a game character class
- Add sound effects and background music to your game
- Grasp how to integrate Vulkan into Visual Studio
- Create shaders and convert them to the SPIR-V binary format

▶Key Features
- Learn how you can build basic 2D and complex 3D games with C++
- Understand shadows, texturing, lighting, and rendering in 3D game development using OpenGL
- Uncover modern graphics programming techniques and GPU compute methods using the Vulkan API

▶Who This Book Is For
If you're a developer keen to learn game development with C++ or get up to date with game development, this book is for you. Some knowledge of C++ programming is assumed.

출판사 서평

▶ Preface
Computer graphics programming is considered to be one of the hardest subjects to cover, as it involves complex mathematics, programming, and graphics concepts that are intimidating to the average developer. Also, with alternative game engines available, such as Unity and Unreal, it is important to understand graphics programming, as it is a lot easier to make 2D or 3D games using these more sophisticated game engines. These engines also use some rendering APIs, such as OpenGL, Vulkan, Direct3D, and Metal, to draw objects in a scene, and the graphics engine in a game engine constitutes more than 50% of it. Therefore, it is imperative to have some knowledge about graphics programming and graphics APIs.

The objective of this book is to break down this complex subject into bite-sized chunks to make it easy to understand. So, we will start with the basic concepts that are required to understand the math, programming, and graphics basics.

In the next section of the book, we will create a 2D game, initially with Simple and Fast Multimedia Library (SFML), which covers the basics that are required to create any game, and with which you can make any game with the utmost ease, without worrying about how a game object is drawn. We will be using SFML just to draw our game objects.

In the next part of the book, we will see how game objects get presented onscreen using OpenGL. OpenGL is a high-level Graphics API that enables us to get something rendered to a scene quickly. A simple sprite created in SFML goes through a lot of steps before actually getting drawn on the screen. We will see how a simple image gets loaded and gets displayed on the screen and what steps are required to do so. But that is just the start. We will see how to add 3D physics to the game and develop a physics-based game from the ground up. Finally, we will add some lighting to make the scene a little more interesting.

With that knowledge of OpenGL, we will dive further into graphics programming and see how Vulkan works. Vulkan is the successor to OpenGL and is a low-level, verbose graphics API. OpenGL is a high-level graphics API that hides a lot of inner workings. With Vulkan, you have complete access to the GPU, and with the Vulkan graphics API, we will learn how to render our game objects.
