Away3D includes a number of classes that can be used to change the way the scene is viewed and how the camera interacts with the scene.

The lens classes ZoomFocusLens, PerspectiveLens, SphericalLens, and OrthogonalLens can be used to provide a traditional view of a scene, a wide-angled view, or a view in which objects don't diminish in size as their distance to the camera increases.

The HoverCamera3D, SpringCam, and TargetCamera3D classes provide a convenient way to track moving 3D objects, and also to view them from a variety of different angles.

We also looked at the various properties of a camera, like fov, zoom, and focus, which can be modified to increase or restrict the view of the scene that a camera has.

In the next chapter, we will take a look at how the mouse can be used to interact with the scene, which also provides an example where it is necessary to use the PerspectiveLens class.
