Man, I was tired of searching for a diffusion video that actually explains how they work in deep. Finally I found It. Thanks a lot. By the way, I would like to know what are the differences between skyline, QRD, Binary etc. in terms of effectiveness, because It seems that it exists a whole lot of different types, and speaking about bandwidth, there exists winners and loosers, but I don't think it works that easy. I think that bandwidth maybe affects the diffusion coefficent, the distribution of the reflections etc.
