algorithmic modeling for Rhino

Rough check that the bending behaviour in Kangaroo is physically correct.
It works in 3D too, but this is a little harder to show in this way.

Special thanks to Chris Williams, Sam Joyce and Moritz Fleischmann !

Thanks a lot!! I was looking for this specific bending curve shown in the video. I manage to make a curve bend but the output was more like a circle than the one in the video. Maybe there is another force being applied at the endpoints? How to make the extremes flattish?

Veronica - an example like the one in this video can be found in the bending directory in the zip posted at the top of the page here:

Daniel, thank you for your amazing work. Can I have this "Kangaroo bending validation" definition to study it? Thanks

thank you! I'll try working in this way. Very helpful :-)

Because the extruded curve remains parallel to one plane, this doesn't help me if i want the surface to twist in any way , but it is a good start in at least knowing the surface length is maintained.

Hi Daniel. 

Very nice work - what do you believe is the best and most correct way to "tell" the curve that it would like to move more in the z-direction than in any other. Would it just be to add an unary force of 1 or something to the points?

Also, I guess this could be found through deeper discoveries of the papers, but do you know where I can find documentation, so that I can set bending, stiffness etc. so that it equals those of different materials. E.g. wood?

Cheers Rasmus

Hi Daniel

Is it possible to bend a rectangular grid in similar way with kangaroo?

Jacob, It worked for me, you need to right click and save the file.

Hi Daniel

The file "bendingexample.ghx" is not downloaded when i use the link? Can you share it again?

Thank you!

Jacob

Hi Henning - try without joining the lines going into the geometry input
