Detailed Description

Camera base class Node.

This Camera class serves as a virtual base class for specific camera implementation (see below).

The Camera class is used by the user, or by a SceneNode to apply camera transformations to a scene. Since a Camera is a type of Node it can be attached within the scene graph in order to follow objects or create other effects.
