Here is another simulation run (~ 2 days). The blue creatures here are equipped with sensors not only for the fruits, but also for their peers. They now seem to act in a more coordinated way.

This is what #Spore should have been

This looks beautiful. Where and how can I access this ?

The simulation in this video was made with an alpha of the next ALIEN version. See my Discord for active discussions about development as well as Windows builds. The source code is freely available on GitHub

incredible. I'm curious how ALIEN's particleprocessor detects collisions efficiently. I have experimented with k-d trees but not really anything else and wonder if I should!

Thank you! The data structure behind the collision detection is essentially a 2D array of linked lists of pointers, whereby the particle position is mapped to a slot in the array. There is no long range interaction and this works quite fast on a GPU.

I've been playing with this tool recently, it's amazing!

Thanks! I'm working on a much better version :) It's currently in alpha state and used in this video.

I don't know what it is but it's mesmerizing !

This looks awesome! I adore ALife.

Do you think one time you would be interested to look into that ? So it can run on AMD & NVIDIA GPU

Yes, this has already been suggested to me ( I will try this API in the future (or someone else who wants to support me).
