How to read GPU Zen?
GPU Zen is not a book that you have to read from cover to cover in a linear fashion. You can read it in any order and at any pace that suits your preferences and needs. However, here are some tips and suggestions that might help you get the most out of the book:
Choose your topics of interest
The book is divided into seven sections that cover different aspects of rendering:
Geometry Manipulation
Lighting
Shadows
Rendering Techniques
Global Illumination
Compute Shaders
VR and AR
You can choose which sections or chapters you want to read based on your interests or goals. For example, if you want to learn more about lighting models and effects, you can read the chapters in the Lighting section. If you want to learn more about ray tracing or voxelization, you can read the chapters in the Global Illumination section. If you want to learn more about VR and AR rendering, you can read the chapters in the VR and AR section.
You don't have to read all the chapters in a section or all the sections in the book. You can skip or skim through the chapters or sections that are not relevant or interesting to you. However, keep in mind that some chapters might have dependencies or references to other chapters, so you might need to read them first or later to fully understand them.
Follow the code examples
The book provides source code and shaders for each chapter that you can download from the official website or GitHub repository. You can run the code on your own machine and see how it works.
