This is done by traversing the scene graph. During this process, each node within the scene is visited once and all the data it contains is sent to the rendering pipeline. A typical scene graph traversal is performed “depth first”, that is, whenever a node with children and siblings is currently visited, the next step will be to first visit its list of children and then continue with its next sibling.Hugoen-us
