Sadly, I don't have access to it... Did anyone read it and know if it's any good?

I had once actually tested similar ideas, but I immediately discarded it since the performance was not really good.

It looks like they achieved around 100M rays per second in fully dynamic scenes. Given that we can trace maybe a few times more than that in static scenes, it isn't too bad, but maybe it still is not worth it. I'd personally just use ray tracing with a tree data structure. The use of uniform grid and limitations on geometry is not very fascinating for practical usage (though it is an interesting research result!)...

Given the picture in the preview you can see on Springer, and the abstract, i would say this is a very "academic" paper.
