Pretty cool idea: "buds compete for light, the tree distributes a growth resource among them, and the successful ones produce new shoots. Those shoots change the light available for the next round. The crown shape emerges from this feedback loop."

I would never have thought to generate tree shapes by simulating real life

oh hey, very nice result! i've been experimenting with trees (using ai) as well - https://treesim.netlify.app/

Nice to see another article from Mr Arion Render, always a pleasure. And of course posted by ibobev, always worth watching his HN submissions.

Very nice overview of procedural tree generation!
