Overview of this book

If you‘re fascinated by the complexities of animating video game characters and are curious about the transformation of model files into 3D avatars and NPCs that can explore virtual worlds, then this book is for you. In this new edition, you’ll learn everything you need to know about game animation, from a simple graphical window to a large crowd of smoothly animated characters. First, you’ll learn how to use modern high-performance graphics, dig into the details of how virtual characters are stored, and load the models and animations into a minimalistic game-like application. Then, you’ll get an overview of the components of an animation system, how to play the animations and combine them, and how to blend from one animation into another. You’ll also get an introduction to topics that will make your programming life easier, such as debugging your code or stripping down the graphical output. By the end of this book, you’ll have gained deep insights into all the parts of game animation programming and how they work together, revealing the magic that brings life to the virtual worlds on your screen.

Building an OpenGL 4 Renderer

Welcome to Chapter 2! In the previous chapter, you learned how to open an application window, including the OpenGL context, and how to perform a very basic operation: clearing the screen in different colors. More actions were not possible due to the limited OpenGL support included in GLFW.

In this chapter, you will learn how to get access to the OpenGL function calls and extensions using a “loader” helper, which is a small piece of code that maps the OpenGL functions to the entry points of the installed system library. We could also do this mapping in our own code, but this would require a lot of extra work. The OpenGL renderer will be enhanced during the book – as the first step, we will only display a textured quad on the screen, consisting of two triangles.

In this chapter, we will cover the following topics:

  • The rendering pipeline of OpenGL 4
  • Basic elements of our OpenGL 4 renderer
  • Buffer types for the...
