Hello Wei !
When you pfDelete a pfGeode, Performer runs pfUnrefDelete on all its geosets.
When you pfDelete a pfGeoSet, Performer runs pfUnrefDelete on all its
pfGeoState's (see man page for pfUnrefDelete).
In other words, if your pfGeode, pfGeoSet, pfGeoState don't have
extra references to them, calling pfDelete on a pfGeode deletes the entire
hierarchy under it.
Objects may have extra references if:
(1) You called pfRef on them.
(2) You added them as children of more than one parent. E.g. A pfGeode can be
added as a child of multiple pfGroup nodes.
