DESCRIPTION
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.
FIELDS
SoSFFloat height
Height of the viewing volume.
FUNCTIONSSoOrthographicCamera * SoOrthoCamCreate()
Creates an orthographic camera node with default settings.
SoType SoOrthoCamGetClassTypeId()
Returns type identifier for this class.
ACTION BEHAVIOR
SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction,
SoHandleEventAction, SoRayPickAction
Sets the viewport and camera information in the state.
