Traversal using recursion Recursive traversal is the best known and most frequently used. Recursive algorithm uses method call stack in order to keep the state of the traversal for every level of a tree. There is a common misconception that recursive algorithms are slow because of the call stack...

pact bitstack, an integer that fits into one or two machine reg- isters. In the bitstack we store skip codes that indicate which siblings of a node must be traversed. Two variations of the algorithm are presented: one vari- ation for 4-way branching MBVHs (MBVH4) and one for ...
