I'm implementing this algorithm and it's working. I can find the point and the time of intersection, but how can i find the normal? Wich face of the box the ray hit? I would appreciate any help.

Unless I am missing something, the normal would be the same as the normal for the plane the ray intersects for T-Near.
Now that i know, seems obvious... Thanks.
