GLFW

Introduction

GLFW is a free, Open Source, portable library for OpenGL and OpenGL ES application development. It provides a simple, platform-independent API for creating windows and contexts, reading input, handling events, etc.

Version 3.0.4 adds better support for custom build environments and fixes for a large number of bugs that together affect all supported platforms. As this is a patch release, there are no API changes.

If you are new to GLFW, you may find the introductory tutorial for GLFW 3 useful. If you have used GLFW 2 in the past, there is a transition guide for moving to the GLFW 3 API.

Compiling GLFW

Using GLFW
