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    
                    
SoSFFloat            height
Height of the viewing volume.

METHODS

       
                    
                     SoOrthographicCamera()
Creates an orthographic camera node with default settings.

    static SoType    
                    
static SoType        getClassTypeId()
Returns type identifier for this class.

ACTION BEHAVIOR

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoHandleEventAction, SoRayPickAction
Sets the viewport and camera information in the state.
