I was watching the anime Psycho-Pass and saw this effect in its ending. I really like the way it looks and is animated, so I want to recreate it. So far the things I know is that the particles are connected by lines and these lines build up triangular surfaces, and the hole thing is being looks like it is been rolled out from the center.
Thank you for every suggestion and idea of how to build this.
