the idea is to use sort-last rendering, i.e. splitting up the scene into
smaller pieces, only some of which are rendered by each node. When
they're done with that, they send their partial image (with depth buffer
if necessary) to the display node which displays the final result. This
is a very cursory view, but if you google sort-last you will find lots
of papers on the topic. In OpenSG that is handled by the SortLastWindow,
which is a specialized ClusterWindow.
