Book Description
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 find expanded content on high-performance graphics and modern animation techniques, along with improved workflows and enhanced guidance on using OpenGL and Vulkan. 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.
What you will learn
- Create simple OpenGL and Vulkan applications and work with shaders
- Explore the glTF file format, including its design and data structures
- Design an animation system with poses, clips, and skinned meshes
- Find out how vectors, matrices, quaternions, and splines are used in game development
- Discover and implement ways to seamlessly blend character animations
- Implement inverse kinematics for your characters using CCD and FABRIK solvers
- Understand how to render large, animated crowds efficiently
