Examples of com.jme3.scene.Node

com.jme3.scene.Node
Node defines an internal node of a scene graph. The internal node maintains a collection of children and handles merging said children into a single bound to allow for very fast culling of multiple nodes. Node allows for any number of children to be attached. @author Mark Powell @author Gregg Patton @author Joshua Slack
