Random Curves

I need to draw lines like these randomly.

I notice that some are open curves, others are “Y” shaped and others are like curved triangles.

How can I do them?

perhaps try a reactive-diffusive algorithm

my guess would be to do use this script (or other fracture/cracking scripts) and randomly cull curves.

It looks like a lot to the work of

They first draw heights then erode between lines

When I see your previous question,

I think we could help better if you explain what you are after. And which workflow you want to use.

I hope to be able to use these patterns to distort the surface and create these waves like in the image above.

I don’t have a defined workflow yet.
