Espresso3D is a high performance real-time 3D engine for the Java(tm) programming language. E3D is not just a scene graph. It aims to be a complete solution for your application with OpenGL rendering, OpenAL audio, collision detection, input, and rendering support.
Espresso3D began as a free for non-commercial use library in October 2004. As of April 8, 2008 Espresso3D is available under the open source LGPL license.
The JOAL Project hosts a reference implementation of the Java bindings for OpenAL API, and is designed to provide hardware-supported 3D spatialized audio for games written in Java. It is part of a suite of open-source technologies initiated by the Game Technology Group at Sun Microsystems, with intention of making the development of high performance games in Java a reality.
This project also hosts the Sound3D Toolkit, a high level API for spatialized audio built on top of the OpenAL bindings. This toolkit is designed to provide access to all the features of OpenAL through an intuitive, easy to use, object-oriented interface.
