An orthographic camera defines a parallel projection from a viewpoint. This camera does not diminish objects with distance, as an OIV.Inventor.Nodes.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 OIV.Inventor.Nodes.SoOrthographicCamera.height field defines the total height of the viewing volume; this and the aspectRatio field determine its width.
See the base class OIV.Inventor.Nodes.SoCamera for more information about the inherited fields.
Useful algorithms for manipulating a camera are provided in the OIV.Inventor.ViewerComponents.SoCameraInteractor class.
