Method Detail

setListener

public void setListener(BSPTreeTraverseListener listener)

Sets the BSPTreeTraverseListener to use during traversals.

setGameObjectManager

public void setGameObjectManager(GameObjectManager objectManager)

Sets the GameObjectManager. If the GameObjectManager is not null during traversal, then the manager's markVisible() method is called to specify visible parts of the tree.

                     Vector3D viewLocation)

Traverses a tree in draw-order (front-to-back) using the specified view location.

traverse

public void traverse(BSPTree tree)

Traverses a tree in in-order.
