Red boxes will contain warnings or other features you have to be extra careful with. To make the concepts easier to follow, and give them some added structure, the book contains boxes, code blocks, color hints and function references.īoxes Green boxes encompasses some notes or useful features/hints about OpenGL or the subject at hand. The concepts are taught in a linear fashion (so it is advised to start from the top to the bottom, unless otherwise instructed) where each chapter explains the background theory and the practical aspects. Each of the chapters can be found at the menu to your left. Each section contains several chapters that each explain different concepts in large detail. LearnOpenGL is broken down into a number of general sections. Most of the functionality doesn't even require you to understand all the math as long as you know how to use it. Don't be scared about the mathematical knowledge required before starting your journey into OpenGL almost all the concepts can be understood with a basic mathematical background and I will try to keep the mathematics to a minimum where possible.

So where necessary I will provide pointers to good resources that explain the material in a more complete fashion. However, I'm not a mathematician by heart so even though my explanations may be easy to understand, they will most likely be incomplete. If you don't have much experience with C++ I can recommend the free tutorials at Also, we will be using some math (linear algebra, geometry, and trigonometry) along the way and I will try to explain all the required concepts of the math required. However, I will try to explain most of the concepts used, including advanced C++ topics where required so it is not required to be an expert in C++, but you should be able to write more than just a 'Hello World' program. Therefore a decent knowledge of the C++ programming language is required for these chapters. Since OpenGL is a graphics API and not a platform of its own, it requires a language to operate in and the language of choice is C++. However, there are a few items that need to be taken into consideration before starting your journey. Doing things by yourself is extremely fun and resourceful and gives you a great understanding of graphics programming. Since you came here you probably want to learn the inner workings of computer graphics and do all the stuff the cool kids do by yourself.
