Java 3D:- Creating a 3d ball using java


Quoted from Wikipedia 


Java 3D is a scene graph based 3D application programming interface (API) for the Java platform. It ran atop either OpenGL orDirect3D until the version 1.6.0 which runs at the top of 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).

Before you could start creating java 3d programs you need to download and plugin it with your IDE.
you could download it from here.
