I want to create a waterdrop where thin lines are wrapped around the object. To be more precise: I just want to see the fine thin lines twisted around the object.
How would you do this? Create them via curves?
I'm surprised that both Chris and Robin Betts provided an interesting answer, but neither of them accurately addressed the actual question ;-)
Hence now the answer to your question (Based on Robin Betts ingenious method of creating the spiral!).
Trim Curve to make only parts of it visible.
PS: If you also use the
Random Value node for scaling, you can vary the size of the individual curves again during instantiation.
if you mean the second picture, you could use geometry nodes with this node setup:
So every edge will be checked whether the z values are not the same, by this all edges which are vertically will be deleted.
so you get this:
then i delete random edges by a noise texture with a decent scale:
ok, finally i made it to build spirals mathematically...
here is the final node tree:
This group will 'Spiralize' a given profile curve, along its local Z..
..setting the Z of a created unit spiral to the Z sampled from the profile, and scaling it in XY by the sampled XY length. For convenience, the modifier lets you adjust the spiral using the modified profile curve, and remove it from the geometry when done.
