Is there anyway to use occulusion culling in Performer? I have a
polygon based occulusion algorithm which culls individual polygons
of an object based on occulders blocking the culled polygon view
from the eye point.

I ask this question because from what I've seen, Performer's culling
capabilities are useful in culling subtrees during traversal but not
individual polygons of a geoset. Am I missing a point here?
