Your brain uses a triangular grid to map out space.

Some UCL neuroscientists have evidence that human (and rat) brains use triangular grids to represent locations in space.

That seems like a good idea for estimating distances. Manhattan distance is a very bad approximator to Euclidean distance. On a triangular grid, however, it's not so bad.

I wonder how this works in 3 dimensions.

Did you seriously just link me to a website used for outsourcing homework essays? That post is complete gibberish. It looks like it was generated by a computer program used to output random English text. Is this some kind of Turing test?
