There are plenty of tutorials out there that teach how to program graphics cards to generate imagery. However, simply following tutorials alone will only get you so far.
Understanding how a Graphics Processing Unit (GPU) works and the theory they're built on will make you a more effective graphics programmer. Think about it for a moment, if you understood how a machine works, what it can do and why, would you be better at using that machine? Absolutely
This e-book will give you this extra knowledge. Once you understand how the GPU works you'll be able to think creatively instead of blindly following tutorials. You'll think of better ways to achieve the results you want, and possibly even come up with new techniques.
What's InsideThe ebook doesn't try to cover everything in full detail. Instead, it covers the core fundamentals you need to get started:
- How the overall graphics pipeline works
- What shaders are, and how they're used
- The various types of data buffers (vertices, textures, etc.)
- How 3D objects and cameras are positioned in 3D space using matrix algebra
- Basic 3D lighting - the Phong lighting model
- Performance tips
- A cheat-sheet for common tasks using OpenGL ES 3, SDL2, and GLM
- A list of useful resources
This e-book is intended to be read with the companion "Getting Started with OpenGL ES 3+ Programming" tutorial series. The tutorials cover the practical "how-to" side; taking you from zero to rendering a basic 3D scene with lighting. Be sure to get the tutorials too.
