# Node information atom container

An atom container that includes general information about the node such as the node’s type, ID, and name.

## Overview

> Important: VR Media is deprecated in the QuickTime file format. The information that follows documents existing content containing VR Media and should not be used for new development.

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.

```
