Java 3D is a scene graph based 3D application programming interface (API) for the Java platform. It ran atop either OpenGL or Direct3D until the version 1.6.0 which runs atop JOGL. Since version 1.2, Java 3D has been developed under the Java Community Process. A Java 3D scene graph is a directed acyclic graph (DAG). 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 true object-oriented approach. 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 Java Development Kit (JDK). == History == Intel, Silicon Graphics, Apple, and Sun all had retained mode scene graph APIs under development in 1996. Since they all wanted to make a Java version, they decided to collaborate in making it. That project became Java 3D. Development was underway already in 1997. A public beta version was released in March 1998. The first version was released in December 1998. From mid-2003 through summer 2004, the development of Java 3D was discontinued. In the summer of 2004, Java 3D was released as a community source project, and Sun and volunteers have since been continuing its development. On January 29, 2008, it was announced that improvements to Java 3D would be put on hold to produce a 3D scene graph for JavaFX〔(【引用サイトリンク】 title= ANNOUNCEMENT: Java 3D plans )〕 JavaFX with 3D support was eventually released with Java 8.〔(【引用サイトリンク】 title= What's New in JDK 8 )〕 The JavaFX 3D graphics functionality has more or less come to supersede Java 3D. Since February 28, 2008, the entire Java 3D source code is released under the GPL version 2 license with GPL linking exception. Since February 10, 2012, Java 3D uses JOGL 2.0 for its hardware accelerated OpenGL rendering, the port has been initiated by Julien Gouesse. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Java 3D」の詳細全文を読む スポンサード リンク
