Hiya,

I have a wee issue with grouping primitives. I have a single mesh ( it comes from an .obj ), with multiple “sub-objects” in it, just connected primitives. I can do a group for each connected primitives with conectivity and partition SOP. But I need to create a group per groups which are intersecting or not far from each other ( with a radius value or something ).

You can see the problem in the screengrab I've attached. I'd like to have group 1-2-3-4 in groupA, 5-6 in GroupC and 7 in Group B.

I'm trying something with a for each node and intersecting vopsop node, but I'm a bit lost, anyone could help me on that ?

Thanks !

I'm not sat at my desk so can't answer in detail, but it may be worth checking out old school's intersecting objects tut…

edit: Sorry, missed what you were saying originally (mobile's not the best forum browser). It's a bit of an awkward one - I'd probably not do it the the most efficiently myself, either through python or by importing groups iteratively into another Geometry node and processing their bounds there, ending up with a final grouping.

Thanks,

The other thing yes is I'd like to avoid using volumes I'll keep searching ! thanks

.. I'll keep searching ! thanks

no wait !

try this suggestion :

- ignore nodes in gray .
- nodes in yellow do the job .
- there is a null to ‘play’ with values just for quick testing ..

yay !!! Thanks a lot that does exactly the job !

Cheers man !

Ohh nice!

I was getting toothache trying to figure this one out… you know, it's always the simple yet elusive solutions that make me feel small…

Nice simple solution…
