There are 100 million particles in this thing. My previous best was 10M. Maybe eventually I'll do a billion! I have their XYZ coordinates and ID => parent ID in a huge 4.2 GB CSV file.pic.twitter.com/5Rc72kahBu

Let's run some numbers, shall we? This is a legitimate tree structure - each particle has exactly one parent (except for the single seed node which is the root). How many children do the nodes have? Mostly 0, 1, or 2. Linear and log scale histograms attached.pic.twitter.com/L7ATK3BQch
So, for any node, you can follow its ancestry all the way back to the root. How deep into the tree are the nodes? Here's a histogram for that. The deepest leaf node is at level 12,793.pic.twitter.com/sy8uyfk4cL
Each node is a distance of exactly 1 unit from its parent. The final bounding volume is: -6556.9824, -6069.568, -6646.6934 5947.792, 6295.334, 6758.1587
Here's a much easier visualization, kinda like an "X-ray". Just alpha composite all the particles in a 2D plane.pic.twitter.com/1sGw9faVvh
Pretty cool!
this is amazing
