oops yes you've got to do something like
this...
pfuTraverser trav;
pfuInitTraverser(&trav);
trav.preFunc = findgeode;
pfuTraverse(r,&trav);
where "findgeode" is of the form
int findgeode(pfuTraverser *trav)
{
if (trav->node->isOfType(pfGeode::getClassType()))
{
pfGeode *model1 = (pfGeode *)trav->node;
int variabile;
ushort *icoords, *inorms;
fVec3 *coords, *ncoords, *norms, *nnorms;
variabile=model1->getNumGSets();
// there are 6 gset
pfGeoSet *gset=model1->getGSet (1);
gset->getAttrLists(PFGS_COORD3, (void**)&coords, &icoords);
}
}
