    How can I calculate the field of view value of the camera from the Focal Lenght and the Aperture Width?
    Wil the result be in degrees or radians.

    Ok, never mind ;-)

    aperture=camera_container->GetFloat(CAMERAOBJECT_APERTURE);
    focus=camera_container->GetFloat(CAMERAOBJECT_FOCUS);
    fov=2*atan(aperture/2/focus);

    Nothing like doing drawings and remembering the old school trigonometry ;-)
