Thanks to the following thread : most efficient AABB vs Ray collision algorithms

I have seen very fast algorithm for ray/AABB intersection point computation. Unfortunately, most of the recent algorithm are accelerated by omitting the "output" intersection point of the box.

In my application, I would interested in getting both the the distance from source ray to input: t0 and source ray to output of bounding box: t1.

I have seen for instance Eisemann designed a very fast version regarding plucker, smits, ... , but it does not compare the case when both input/output distance should be computed see: http://www.cg.cs.tu-bs.de/publications/Eisemann07FRA/

Does someone know where I can find more information on algorithm performances for the specific input/output problem ?

Thank you in advance
