## 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.

## METHODS

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

**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.

## FILE FORMAT/DEFAULTS

viewportMapping	ADJUST_CAMERA
position	0 0 1
orientation	0 0 1  0
aspectRatio	1
