The View::computeIntersections(..) method allows you to pass in the TraversalMask to use, it's 0xffffffff by default. > My understanding the mask is a 32 bit value, this means I can only have a > maximum 32 types of nodes to be shown/hidden because an AND operation is > performed? Yes. Typically one would have broad catagories of nodes that you want to interact with in different ways. If you need more than 32 categories then you'll need to use custom callback or node inserted in the scene graph in combination to state attached to the visitor to decide whether a subgraph should be traversed or not.
