LookAt generates a trivial transformation matrix that will orient one node to "look at" another. Specifically, LookAt takes the vector connecting the origins of its two input matrices (the "look" vector), and converts it into a rotation. Note that this process does not preserve any notion of a natural "up" or "down", so an object controlled by LookAt may be rotated around the look vector in nonintuitive ways.

ViewMatrix, which has explicit control over the "up" vector.
