if you are asking how to convert the tree item into the selected node, just set each node's ID appropriately, and when selecting the treenode, get the data from it and search for the node with that id.

if you are asking how to highlite a node in the 3d scene,
and your scene uses lighting, when you select the node simply turn it to not use light. It will appear brighter than the remaining nodes.
