Think of the way that terrain based games use level-of-detail
computations (LoD) to figure out which portions of the screen need to be
updated. Think of the use of acceleration structures (e.g. k-D trees,
BSPs, etc) for scene-graph culling. Think of the use of expose events
and dirty-masks to describe exactly which parts of the screen need to be
rendered vs. simply blitted from elsewhere in video memory.
