Java 3D is a scene graph-based 3D application programming interface (API) for the Java platform. It runs on top of either OpenGL or Direct3D. Since version 1.2, Java 3D is developed under the Java Community Process. JSR 926 specifies Java 3D 1.4; as of 2007, the current version is 1.5.1 (released in June 2007).
Compared to other solutions, Java 3D is not only a wrapper around these graphics APIs, but an interface that encapsulates the graphics programming using a real, object-oriented concept. Here a scene is constructed using a scene graph that is a representation of the objects that have to be shown. This scene graph is structured as a tree containing several elements that are necessary to display the objects. Additionally, Java 3D offers extensive spatialized sound support.
Java 3D and its documentation are available for download separately. They are not part of the JDK 6. However£¬future versions of the JDK are expected to include an API package for Java 3D.
