AFAIK, yes. Doing a bounding sphere test first will eliminate a lot of cases, though. If you''re worried about performance, you might also want to transform the segment into the model space of your cube. I''ve never compared the performance of doing that vs doing straight segment-to-plane collision.

There are a lot of other optimizations to consider, of course.
