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
