perhaps you can make an field of view
object, like a flattened cone, for both the head and the
eyes.
then test collision for the head fov cone and for
the eyex (the eyes should be wider than the head, i'm not talking scientific fov
cones. ) then if you'r target object is inside of collides with the eyes field
of view cone. the eyes perform a lookat BB at say 10 percent
following speed
(which is pretty fast) a little later the when the
object collides with the head fov cone, it will also lookat , but only with a 1
% following speed.
so the eyes catch the target first to be later and
more slowly followed by the head..
using just collision detection BB and lookat,,
avoiding all the nasty maths..
hope this is something like you'r
describing..
