Although not 100% accurate, in the sense that it may report intersections even when the objects do not actually collide (but for that a more complex solution like GJK could be easily used), here's the solution I came up with after reading Dave Eberly's original paper on OBB vs moving triangle intersection test. In that paper, the intersection test is ...


An oriented bounding box is delimited by six planes (one for each face). A triangle is also delimited by three lines (one for each sides). A naive implementation (which often a good idea to start with) is thus to compute the intersection of any triangle edge with any plane and to check whether at least one intersection occur within an edge of a triangle ...


mklingen's comment answered my question. I was correct in my initial guess.
