  52  * Base class for a camera used to render a scene.
  53  * The camera defines the mapping of the scene coordinate space onto the window.
  54  * Camera is an abstract class with two concrete subclasses:
  55  * {@link ParallelCamera} and {@link PerspectiveCamera}.
  56  *
  57  * <p>
  58  * The default camera is positioned in the scene such that its projection plane
  59  * in the scene coordinate space is at Z = 0, and it is looking into the screen in
  60  * the positive Z direction. The distance in Z from the camera to the projection
  61  * plane is determined by the {@code width} and {@code height} of the Scene to
  62  * which it is attached and its {@code fieldOfView}.

  65  * <p>
  66  * The {@code nearClip} and {@code farClip} of this camera are specified in the
  67  * eye coordinate space. This space is defined such that the eye is at its
  68  * origin and the projection plane is one unit in front of the eye in the
