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.


SoSFFloat height

Height of the viewing volume.



Creates an orthographic camera node with default settings.

static SoType getClassTypeId()

Returns type identifier for this class.


SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoHandleEventAction, SoRayPickAction

Sets the viewport and camera information in the state.
