Hi
I make a little UP because I go now a strange problem :
My Cullcallback seem to engender some other problems in my application. When
I put it, the application can crash or freeze, pretending sometimes "not
enough memory" (false, I've checked) or some other error messages with no
relation with that. I suppose my cull callback is not good and randomly
engender unstable states in the application...
This is what I do, to check visible elements or not :
Callback :
tileVisibleCallback::tileVisibleCallback(Tile* tile)
> : osg::NodeCallback(){
> _tile = tile;
> };
>
> void tileVisibleCallback::operator()(osg::Node* node, osg::NodeVisitor*
> nv){
>
> if(!_tile.valid()){
> osg::notify(osg::WARN)<<"Tile callback error : tile not
> recognized!\n";
> return;
> }
>
> //This method is called so the tile is visible
> // Its name is added to the visible Tile list.
> _tile->_stack->_cullList.push_back(_tile->getName());
>
>
> traverse(node, nv);
> };
>
and the Set :
osg::ref_ptr<tileVisibleCallback> tvc = new tileVisibleCallback(this);
> if(_mainChild->getCullCallback())
> _mainChild->getCullCallback()->setNestedCallback(tvc.get());
> else
> _mainChild->setCullCallback(tvc.get());

Do you see something not clear ? unstable ? what can engender problems ?
Thanks a lot.

Vincent
