The Project View shows the whole project and all its contents in a hierarchical structure. At the top, the hierarchical structure shows the four main concepts that we have discussed earlier; Data Sources, Layers, Scenes and Streams, as seen in Figure 15.2. When you unfold one of these top items, the contents for the respective category is shown in the view.
You interact with the items in the Project View by either double-clicking on them to activate them or by clicking with your right mouse button to bring up a context menu for an item. The context menu shows the possible operations that can be performed on the item.
A newly created project only contains one default layer, which is empty. You can insert objects into this layer to start your work. The project also contains one scene that uses the layer and one stream that displays the scene.
How to work with the four different categories in the Project View is further described in Chapter 16, Project, which describes the project concepts in detail.
