Appendix C. ES Framework API

The example programs throughout the book use a framework of utility functions for performing common OpenGL ES 3.0 functions. These utility functions are not part of OpenGL ES 3.0, but rather are custom functions that we wrote to support the sample code in the book. The ES Framework API is included with the source code for the book available from the book website at opengles-book.com. The ES Framework API provides routines for tasks such as creating a window, setting up callback functions, loading a shader, loading a program, and creating geometry. The purpose of this appendix is to provide documentation for the ES Framework API functions used throughout the book.

O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.

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.
