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.
