Building a Scene Graph
A Java 3D virtual universe is created from a scene graph. A scene graph is created using instances of
Java 3D classes. The scene graph is assembled from objects to define the geometry, sound, lights,
location, orientation, and appearance of visual and audio objects.
A common definition of a graph is a data structure composed of nodes and arcs. A node is a data
element, and arc is a relationship between data elements. The nodes in the scene graph are the instances
of Java 3D classes. The arcs represent the two kinds of relationships between the Java 3D instances.
