List Join¶

Functionality¶

This node joins different list into a single one.

level 1: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ (1,2,3), (4,5,6), (7,8,9), (10,11,12) ] ]

level 2 mix: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ (1,2,3),(7,8,9),(4,5,6),(10,11,12) ] ]

level 2 wrap: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ [ (1,2,3),(4,5,6) ], [ (7,8,9),(10,11,12) ] ] ]

level 2 mix + wrap: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ [ (1,2,3),(7,8,9) ], [ (4,5,6),(10,11,12) ] ] ]

level 3: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ [1,2,3,4,5,6,7,8,9,10,11,12] ] ]

level 3 mix: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ [1,7,2,8,3,9,4,10,5,11,6,12] ] ]

level 3 wrap: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ [1,2,3,4,5,6],[7,8,9,10,11,12] ] ]

level 3 mix + wrap: [ [ (1,2,3), (4,5,6) ] ] + [ [ (7,8,9), (10,11,12) ] ] = [ [ [1,7],[2,8],[3,9],[4,10],[5,11],[6,12] ] ]

level 2 Match: [[1, 2, 3], [4, 5, 6]] + [[7, 8, 9]] = [[1, 2, 3, 7, 8, 9], [4, 5, 6, 7, 8, 9]]

level 2 Match + Mix: [[1, 2, 3], [4, 5, 6]] + [[7, 8, 9]] = [[1, 7, 2, 8, 3, 9], [4, 7, 5, 8, 6, 9]]

level 2 Match + Wrap: [[1, 2, 3], [4, 5, 6]] + [[7, 8, 9]] = [[[1, 2, 3], [7, 8, 9]], [[4, 5, 6], [7, 8, 9]]]

level 2 Match + Mix + Wrap: [[1, 2, 3], [4, 5, 6]] + [[7, 8, 9]] = [[(1, 7), (2, 8), (3, 9)], [(4, 7), (5, 8), (6, 9)]]

Match: length of lists will be matched before joining
Match mode: how length of lists should be matched (Repeat Last, Cycle, Match Short…)
Mix to mix (not zip) data inside
Wrap to wrap additional level
Levels level of joining

In the N-Panel (and on the right-click menu) you can find:

NumPy Mode: When enabled the node will expect and produce lists of NumPy arrays. It will be faster when joining NumPy Arrays but due the nature of the implementation it will fail when trying to join arrays with different axis number.
