LWJGL (https://www.lwjgl.org) is a Java library that enables cross-platform access to popular native APIs useful in the development of graphics (OpenGL/Vulkan), audio (OpenAL) and parallel computing (OpenCL) applications. This access is direct and high-performance, yet also wrapped in a type-safe and user-friendly layer, appropriate for the Java ecosystem.
LWJGL is an enabling technology and provides low-level access. It is not a framework and does not provide higher-level utilities than what the native libraries expose. As such, novice programmers are encouraged to try one of the frameworks or game engines that make use of LWJGL, before working directly with the library.
LWJGL is open source software and freely available at no charge.
If you'd like to contribute, see doc/README for a quick overview of the project structure, installation instructions and configuration options.
As of version
3.1.0, LWJGL is distributed as a set of modules. Only the
core module is required and all bindings are optional (but some bindings
depend on other bindings). The easiest way to download LWJGL is to use the
build configurator on the website.
The build configurator generates Maven & Gradle declarations that can be added to existing projects. This is the easiest way to use LWJGL while developing.
LWJGL can also be downloaded as a simple set of JAR files. Each module consists of the following files:
To compile and run an LWJGL application, the base and natives JAR files of
the core module and each binding used should be added to the classpath. LWJGL
extracts the natives to a temporary folder and loads them automatically, so
no further configuration is necessary. If more customization is required
(e.g. when creating a platform-specific installer) the natives may be
extracted manually and loaded via
java.library.path. See the Configuration
class for more options.
LWJGL 3 requires Java 8 or later to build and run and currently supports the following platforms/architectures:
For migrating LWJGL 2 code to LWJGL 3, see the Migration Guide.
Most common issues faced by LWJGL users are trivially addressed with the following:
LWJGLX/debug is a Java Agent that will automatically detect a lot of these issues. It can also generate a trace log that's useful when reporting issues to LWJGL.
When asking for help or when you suspect a bug in LWJGL, preparing an MVCE (Minimal, Complete, and Verifiable example) that reproduces the issue will improve the chances of a quick and useful response.
