Multiply 3 arrays of points to construct 3d point cloud

GH-KN · March 17, 2021, 7:00pm

Hi,

Fairly simpel question but I cant find.
I would like to create a point cloud based on 3 input lists.

list 1: points in x direction
list 2: points in y-direction
list 3: points in z-direction

multiply points to create a 3d point cloud of;
3x3x3=27 points

Any suggestions?
something with cross referenc? but how in 3 directions?

Something like this? points.gh (3.5 KB)

or use Array

Hi,

Thank you for your answer, I forgot my file to add (is available now).
Your solution is close.
However, in my example we already have points ‘before’ te CrossRef component.

And I didn’t manage to combine the point via the Crossref.
Do you have any suggestions?

Thank you in advance

many output points are the same…

This only works because your initial points are so nicely ordered. (1st set X-coordinates, 2nd set Y’s and 3rd set Z’s). I have a feeling there is a much smarter way of doing this. 2021-03-18 Combine point array - to generate 3d point cloud_re_RE_ME.gh (15.9 KB)
