OpenGLBook.com is a free OpenGL programming tutorial in online book format. Click on The Book to start learning OpenGL 4.0. Several chapters contain OpenGL 3.3 compatible code samples in a sub-directory named "compatibility" in the source code listing, if you only have access to OpenGL 3 / DirectX 10 level hardware.

Create an OpenGL context with FreeGLUT; Initialize GLEW; Create the boilerplate code used throughout the book; Check the requirements before continuing

Preface: What is OpenGL? Learn about some of the history behind computer graphics and how OpenGL came to be. Also includes an important requirements section. Chapter 1: Getting Started Learn how to set up a rendering window using FreeGLUT, GLEW, and of course OpenGL functionality. Chapter 2: Vertices and Shapes

Modeled after the long abandoned but still popular GLUT library (OpenGL Utility Toolkit), FreeGLUT provides a modern Open Sourced alternative that is easy to use, cross platform compatible, and suitable for creating demonstrative programs such as the ones in this book.

Indices is defined as a GLubyte array of 48 elements; GLubyte is the OpenGL data type for an unsigned byte (unsigned char). You could use any of the following unsigned integral OpenGL data types: GLubyte , GLushort , and GLuint , since indices are never negative (signed) or …

In OpenGL, the components of a vertex are represented through floating point numbers: since a triangle has three vertices, and a vertex has four dimensions, we must create twelve floating point numbers to represent our triangle.

If you're learning OpenGL, it's very likely you're doing so to learn how to render three-dimensional data. In this chapter, we'll be placing our very first step in the world of three-dimensional computer graphics.
