How are these sort of forms created?

I have always wondered how these forms were created. Are they modelled out of nurbs directly in rhino or is grasshopper. Would the curves be time consumingly drawn in rhino then lofted?

I wasn't able to find the answer out myself so.

Anyway thanks for your feedback.

There's a lot of ways to end up with this kind of geometry. Perhaps it is lofted along the wave from section curves. Perhaps it is lofted perpendicularly from S-shaped splines. Perhaps it is created from control-point grids based on hand-drawn geometry guides. Perhaps it is created from control-point grids based on mathematical equations. Perhaps it is the result of a series of spatial morphs such as bending or UV mapping. Perhaps (though it seems unlikely in the case of the image you posted) it is the result from a bottom-up process. Perhaps it is the result of surface blending between partial fragments.

Perhaps it is entirely made by hand.

thanks for the reply.

So it is basically modelled in rhino without the use of grasshopper.

thanks

looks like a blend between curves or surfaces.

I have no idea who made it or how. It's certainly possible they made it by hand.

It is the work of http://alexhogrefe.squarespace.com, pretty sure he first just modeled it with a physical model in paper. Anyway here is an idea to get some similar stuff although here i use 2 guide surfaces you may need 3 or 4 to get the blend path right.

Actually, he use sketchup with a lofting plugin.

Maybe. I was just remembering a paper model of it I saw on his blog along time ago.

Thanks for this, I didnt expect a definition but that helps me a lot.

If architecture art should be, is the interaction with your
Feeling important. Due to the special opportunity of
Grasshopper, all possible parameters in real time to
change, it is essential for such an application, the
first choice!
