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.

Basic elements of the OpenGL 4 renderer

To be able to use OpenGL in our code, we need access to its functions and extensions. Unfortunately, the graphics card vendors do not create these functions in an easy-to-use way. They are stored as function pointers, which will be hard to use.

To translate the function pointers back to more human-readable function names, several helper libraries exist. We will use the Glad tool for this translation.

The OpenGL loader generator Glad

Glad is a free and open source loader generator; all parts to make OpenGL fully available for us are included. Glad supports all OpenGL versions, even back to the first version (1.0), plus the mobile variant OpenGL for Embedded Systems (ES) and the platform-specific APIs for Microsoft Windows and the X Window System of Unix.
