Camera interface storing reference viewpoints.

The camera is a simple record of parameters that can be used to setup the ART::IObserver singleton. Cameras can be retrieved from the editor after exporting data from it.

Public Functions

SET_CID(CID_class_ARTICamera)

virtual RED::Object *GetParentCelestialBody() const = 0

Gets the camera parent celestial body.

The body can be a ART::Planet, a ART::Star. In this case its coordinates are in the parent referential. Or it can be NULL and its transform will be relative to the world coordinate system.

Returns:The parent celestial body.

virtual const RED::Matrix &GetMatrix() const = 0

Gets the camera transform.

If the camera has a parent body, its transform will be relative to it. Otherwise its transform will be relative to the world coordinates system.

Returns:a reference to the transform matrix.

virtual double GetFOV() const = 0

Returns:The camera half horizontal field of view in radians

virtual double GetFocusDistance() const = 0

Returns:The camera focus distance in meters
