Initializing OpenGL: A Sadistic Approach to Modern OpenGL

A book written in my own spare time, that has notes on how to begin an OpenGL project. The main goal of writing this book, is so a complete beginner can follow along and learn as much as they can with a ton of information as possible. And it is because of this goal, I need to cite a lot of references and do research to make sure the information I got is accurately represented to the readers. And it will take a while to complete each chapter.

OpenGL versions	Goals
1.X, 2.X, 3.2+, 4.X	Initialization only
3.1	Outlier OpenGL support
any	Depends on book progress
4.6	End goal

Currently, the book is not done, but I am releasing an "alpha" version of the book. It's provided both as a DOCX file, and a PDF file for viewing pleasures. This is a reward for you searching and lurking on Github, or that somehow this book was found by a search engine, and you just so happened to see this book appearing in the search results. And thus, it is why this book is secretly hidden away online.

DOCX file must embed system fonts for compatibilty with Windows, MacOS X, and Ubuntu/Linux.

Scroll on down to see the future roadmap. Table of Contents will be updated whenever new contents are added to the draft.
