When you create a Vuo composition in the Vuo editor, you drag nodes from the Node Library onto your composition. Each item in the Node Library is a node class, or type of node. When you add a node to your composition, you're creating an instance of a node class. This documentation explains how to develop new node classes, which you can add to your Node Library and share with other Vuo users.
To learn how to develop node classes, see:
