public class SoOrthographicCamera extends SoCamera
Orthographic camera node. An orthographic camera defines a parallel projection from a viewpoint. This camera does not diminish objects with distance, as an SoPerspectiveCamera does. The viewing volume for an orthographic camera is a rectangular parallelepiped (a box).

By default, the camera is located at (0,0,1) and looks along the negative z-axis; the position and orientation fields can be used to change these values. The height field defines the total height of the viewing volume; this and the aspectRatio field determine its width.

See the base class SoCamera for more information about the inherited fields.

Useful algorithms for manipulating a camera are provided in the SoCameraInteractor class.
