Node information atom container

Overview

The node information atom container includes general information about the node such as the node’s type, ID, and name. The node information atom container also contains the list of hot spot atoms for the node. A QuickTime VR movie contains one node information atom container for each node in the file. The routine QTVRGetNodeInfo allows you to obtain the node information atom container for the current node or for any other node in the movie.

The following shows the structure of the node information atom container.
