com.jme3.scene.Spatial
Spatial defines the base class for scene graph nodes. It maintains a link to a parent, it's local transforms and the world's transforms. All other scene graph elements, such as {@link Node} and{@link Geometry} are subclasses of Spatial. @author Mark Powell @author Joshua Slack @version $Revision: 4075 $, $Data$
