I used ChatGpt for this. You tell the IA what the script should do and you get it. Analyze it, break it down to components, ask for a OOC architecture. Very manageable and I have to say I HATED Python. Now, it's better.

@Victor Stepanov Yesterday, I was a bit tired so my answer wasn’t that helpful. Here is a more accurate one. I describe the problem to ChatGPT to give the AI a global view of the architecture. I listen to the remarks. Discarded some, took some in. Since Java is the language I like most, I ask the AI to build me a java application that will do it but here you mist go step by step. In my case the first step was to build a bridge between Java and Blender. Then to have the bridge do what is needed in Java. Then I build a GN that reproduce the first parts of the scripts, the parts I already did with GN. Then I asked it to build java classes that do what I couldn’t do in GN. In my case I got 3 Java classes. I analysed them, tweaked them and got it perfect. Then I asked the AI to give me the schematics to building a GN that would do the same. Since it’s pure maths the transcription isn’t that difficult. And there you are, you have a GN that behave exactly like it should.

@Zbyszek Pietras How good at Blender are you? Do you know how to have instances on point aligned perfectly? At the moment they turn around like horses in a carrousel .
