Also, when GI is used in animation, it's usually rendered in an application that can preserve the initial calculations to a file, and then simply "add" to that original solution at each frame, instead of calculating all over again from scratch. Makes for a much faster GI solution over multiple frames where the camera is in motion. Otherwise, GI is faked using ambient occlusion techniques, or professional light rigging. :-) Direct lighting is still the fastest, and most widely used lighting meathod for professional use. Although true GI does look better.
