I have two curves: one - spiral with, let's say, 100 control points, and the second one - line with 20 points. Now, I want to move the yellow curve along spiral with geometry nodes. How to do this? I know how to instance on points etc, it is not a problem. Instead I just want to move all the yellow one to the top of the spiral. I think that I have to offset the position of the first yellow control point to the second, and so on, of the spiral, but don't know how exactly.
you could e.g. use this node setup:
to get this:
be aware: I am using the newest 3.5 Blender alpha version - so there is no transfer attribute anymore. It was replaced by 3 other nodes. That's why i use "sample index" node here. But of course you can achieve the same result with the transfer attributes node on an older version of Blender.
