Advanced Grafting: How to multiply trees with other trees?

[henry.langner]

Hi everybody!

Grafting. Try it out they said. It’ll be fun they said. So I did. And actually I had some fun in the last few years, but now:

I have a tree that I want to do operations on. As long as the operation is simple, it is no problem (see first three workflows in the screenshot). However, how can I perform operations, where each branch of a tree is performed on each branch of the other tree (4th workflow in the screenshot(fake, ofc))? Is it even possible?

The example above with numbers is very simple. The real problem I want to solve is however with points and vectors. I want to translate three lists of points by four vectors, so I get twelve new lists of points. I can build that by translating one of the lists by the four vectors and then copy the workflow for each list. But that annoys me because then I am committed to the number of lists and my workflow is less flexible as it could be.

just a note, on your 2nd example, this is how data-matching happens:

there’s also a sort of recent thread where the same topic was touched:

Match trees by branch paths - find corresponding item indices by branch

that is a bit painful my best guess is, given tree_A and tree_B: graft tree_A in such a way each branch carries just one single item in tree_B, duplicate branches times the amount of respective elements in ungrafted tree_A then Mass Addition to OR everything together and get one single boolean per branch, then Trim Tree et voilà visually: [image] Cull lines_Re_Re.gh (22.3 KB)

here is one way, where for each single element in A gets multiplied by the full B:

and here where each element of B multiplies the full list of A:
