Java OpenGL (JOGL) is a wrapper library that allows OpenGL to be used in the Java programming language. It was originally developed by Kenneth Bradley Russell and Christopher John Kline, and was further developed by the Sun Microsystems Game Technology Group. Since 2010, it has been an independent open source project under a BSD license. It is the reference implementation for Java Bindings for OpenGL (JSR-231).
JOGL allows access to most OpenGL features available to C language programs through the use of the Java Native Interface (JNI). It offers access to both the standard GL* functions along with the GLU* functions; however the OpenGL Utility Toolkit (GLUT) library is not available for window-system related calls, as Java has its own windowing systems: Abstract Window Toolkit (AWT), Swing, and some extensions.
The base OpenGL C API, as well as its associated Windowing API, are accessed in JOGL via Java Native Interface (JNI) calls. As such, the underlying system must support OpenGL for JOGL to work.
JOGL differs from some other Java OpenGL wrapper libraries in that it merely exposes the procedural OpenGL API via methods on a few classes, rather than trying to map OpenGL functionality onto the object-oriented programming paradigm. Indeed, most of the JOGL code is autogenerated from the OpenGL C header files via a conversion tool named GlueGen, which was programmed specifically to facilitate the creation of JOGL.
