  That looks a lot like a spline declaration.

  Make a spline for the location using the time and pos values and another
spline for the look_at using the same time values and the look values.
Then just call the spline with the time variable, and there you are.
  Besides, you get all kind of nice interpolations (besides linear one)
for free.
