Cluster culling is basically culling which is sensitive to orientation - a bit like back face culling, the difference being that cluster culling takes a whole set of seperate primitives (or even a whole subgraph) into account. I use it particularily with geocentric databases, culling tiles or text that is on the farside of the earth w.r.t the viewer.
