Matrix4x4 The resulting transformation matrix.
Create a "look at" matrix.
Given a source point, a target point, and an up vector, computes a transformation matrix that corresponds to a camera viewing the target from the source, such that the right-hand vector is perpendicular to the up vector.
The resulting matrix corresponds to Matrix4x4.TRS(from, Quaternion.LookRotation(to-from, up), Vector3.one).
