I have the following code to use pfNodeTravFunc :

....
root = (pfGroup *)LoadFile(DatabaseFiles[i], NULL);
pfAddChild(ViewState->sceneGroup, root);
pfNodeTravFuncs(root,PFTRAV_CULL,PreNodeCull,NULL);

....

long
PreNodeCull(pfuTraverser *trav, void *data)
{

   Here, I first want to check the type of node being traversed.
   If it is of type geode, I want to do further calculations here
    
   return PFTRAV_CONT;
}

The problem that I am facing is within the PreNodeCull function.

For starters, I am just checking the contents of
trav->node,
trav->mstack
and they are always 0x0.

Do I have to initialize the pfTraverser *trav
or am I missing something here?

Appreciate any help that I can get

Thanks
Rama
