Xj3D is a Web3D Consortium open-source project for the development of a stand-alone Java-based X3D player. The project is currently run by source@web3D.org community effort, with Naval Postgraduate School (NPS) contributors leading Xj3D Evolution efforts for integrating orphaned projects and building an effective open-source community on SourceForge. Significant previous development work was performed by Alan Hudson, Justin Couch and Rex Melton at Yumetech. Xj3D is used to demonstrate many capabilities for X3D specification development and supports a variety of valuable projects.
