Hi Jesus, I don't really know of an automatic way to produce something like that, you're probably going to have to do it by manual arrangement. 
 
But it's a difficult process to try and keep the same rigid shapes while at the same time trying to compress the overall organization flow down to a single point. 
 
Like macray mentions, the real microphone doesn't try to do that and instead tries to keep the pattern going over the top instead of compressing it down to a single point at the top. So that means that you're looking for some kind of different pattern than the real microphone...
