Lightweight Java Game Library

The Lightweight Java Game Library (LWJGL) is an open-source Java software library for video game developers. It exposes high performance cross-platform libraries commonly used in developing video games and multimedia titles, such as OpenGL, Vulkan, OpenAL and OpenCL. It further provides access to controllers such as gamepads, steering wheels and joysticks in a platform-neutral way.

The primary goal of the project is to provide a way for Java developers to get access to resources that are otherwise unavailable or poorly implemented on the existing Java platform. The main philosophy is to expose underlying technology as a thin wrapper, thus creating an API close to the original. It is also the basis of many high-level Java game engines and libraries, such as libGDX or the jMonkeyEngine.

LWJGL is available under a BSD license.

On 13 November 2014 version 3 was announced, which was released in alpha version on 27 April 2015 and is a complete rewrite of LWJGL. Many new bindings, including GLFW, EGL and Objective-C, were added. Support for Oculus Rift development was also added with LibOVR bindings. The new version was released on 4 June 2016, after more than 3 and a half years in development.

The library accesses native C code through the Java Native Interface (JNI). Bindings to each of the native libraries exist as different modules so developers can make custom builds with only the things they need in a certain program.
