Hi Angela,

You could start with simple helicoids made from mesh quads like this, and subdivide in WeaverBird

Mirroring and joining these as I describe in that essay, then relaxing in Kangaroo would allow you build up simple Rheotomic surfaces. By playing around with the topology of the starting mesh you could vary it to get more interesting forms.

This is quite different to the complex analysis based method I originally used to generate the surfaces, but should give similar results. It was a favourite project of mine, and it should be interesting to now revisit it with Kangaroo

thanks for info

I’ve used one that does exactly that.
