Why is c_trav calculated as a ratio? I thought c_trav represents the cost to do the bounding box intersection test. If c_trav is just a constant (1/8 or 1/1.5), why do we bother to add it to the cost at all since every cell's cost will have this term?

Also, what do cost to traverse and cost to intersect triangle represent mean?
