Overview

In a world where everything from how we take pictures to how we get our food is designed to happen as quickly and easily as possible, it can take a lot longer to learn how to make it all work behind the scenes. Theories and concepts can weigh you down when all you really want to know is how to create, design and go. That's where OpenGL SuperBible comes in. Complete with supporting figures and a CD packed with free tools, demos and libraries, OpenGL SuperBible simplifies 3D programming concepts without wasting your time with programming theory. Mac and Windows users will both find this comprehensive hands-on guide helpful as you learn to program for games, visualization applications and multi-platforms. This is the ultimate resource for any new programmer.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
