ABSTRACT
This chapter discusses the game engines—their history, how they work, and what they do for the game makers. It discusses shaders—which are small programs that create visual effects—and another on physics engines—the part of game maker's game engine that provides them with realistic. Game engines can be written in a wide variety of programming languages. Traditionally, the core of a game engine is written in a robust general-purpose programming language such as C++ or C#. In game makers play analogy, delta time (DT) is the amount of time the curtain is down measured in milliseconds—hiding the update phase from the audience. The update phase is designed to tell each piece of code, that it's time to perform the next action. Rendering is the process of generating images from that code and getting it to the screen. In today's games all rendering happens on graphics hardware: a Graphics Processing Unit (GPU).
