This paper proposes a new method for fast ray/axis-aligned bounding box overlap tests. This method tests the slope of a ray against an axis-aligned bounding box by projecting itself and the box onto the three planes orthogonal to the world-coordinate axes and performs the tests on them separately. The method is division-free, and successive calculations are independent of each other. No intersection distance is computed, but it can be added easily. Test results show the technique is up to 18… 
Ray Tracing using Hierarchies of Slab Cut Balls
TLDR
Experimental comparisons to other commonly used enclosing shapes reveal that the slab cut ball is attractive, and outperforms the sphere in all tested scenes with speed-up factors between 1 and 4.

Fast Ray-Axis Aligned Bounding Box Overlap Tests with Plucker Coordinates
TLDR
This method tests the ray against the edges comprising the silhouette of the box instead of testing against individual faces, which simplifies the technique and shows the technique's performance is up to 93% faster than traditional methods if an intersection distance is not needed.

TLDR
A version of this routine that uses IEEE numerical properties to ensure that those tests are both robust and efficient is described.
