Lately I've worked on a KD-Tree implementation.
I've programmed a 2D log system using OpenCV which allows the visualization of the data structures.
After some test, a nice idea came up to my mind! Why shouldn't I post my data structures as a piece of mathematical art to launch my blog?! ;)
PS: As you can see the point x=0 of the sinc is not in the correct position! I have left it, so that it would remaind me that a PC doesn't know the concept of limit
