algorithmic modeling for Rhino

A mesh consisting of 4 flat surfaces is relaxed to a cone-like shape by using the Hinge Force in Kangaroo. It's a bit tricky to make it out in the (yellow) GH model so check the baked examples "Before" and "After", they show the difference pretty well.

Can you share the definition please? I'm trying to learn. Thank You.

Hi Benjamin. For the moment I'm just playing around with Kangaroo, but I guess it's part of a more long term goal to be able to model free-form developable structures that curve according the rules of bending geometry. The Hinge Force is a big jump forward in this investigation! /MÅRTEN

Martin, I have always enjoyed your empirical testing, and have followed your Geometry of Bending blog from the beginning. Do you have any new fabrication or testing projects on the horizon?

Thanks a lot Marten ! Will read this ASAP.

The unrolled shape is exactly the same for both versions (they are both developable). "Before" is made of 4 flat surfaces and "After" is part of a cone. Daniel Piker gave me this link with some explanations of the Hinge concept:

Thanks Marten! What are the properties of the relaxed cone in comparison to the flat one?

many thanks. that's really nice.

I've posted the example above, here:
Please note that it requires Kangaroo version 0065 or later, with the Hinge component. I think it will be public soon. You also need the WeaverBird plug-in by Giulio Piacentino. The C# code component used in this definition to sort out hinge verticies was written by Daniel Piker.

dear Mårten, would you share this hot stuff? (:
