We are developing a Performer application in we which
traverse and update the database hierarchy loaded by
the Performer openflight loader.
In particular, we insert groups and geodes into the
tree at various levels using the performer routines
pfAddChild() and pfReplaceChild().

The resulting tree appears to be correct, however all
nodes that we add manually ALWAYS pass culling with
"trivially accepted", even when they are not visible.

We have attempted recalculating the bounding volumes
of the entire tree after all updates, but that has not
affected the results.

Is there further action necessary when inserting children
into the hierarchy, or are there restrictions in adding
children ?
