Hello fellow Rhino users,
I’m trying to model some inflatable items. Now I get stuck on modeling the creases and overlapping edges which are typical for an inflatable object. Could someone point me in the right direction wich approach is the best to take.
This look is what I’m trying to achieve
Any experience with kangaroo?
Or more generally : My bookmark
I’m not familiar with Kangaroo. But I see it does simulations. I’m not looking for a simulation but I’m trying to make a still object that has the creases and weld seam like in the picture above.
Simulation is the best but you can achieve very good results with SubD modeling as well.
Don’t go for nurbs, it will be too complex.
here is a quick approach with Kangaroo. I added some parameters like, smootheness and bending/axial stiffness of the border. Not the most beautiful carrots, but maybe by chanigng the stiffness parameters you might get better results.

this approaches almost the desired result. I will install kangaroo and will give it a shot. While I’m not familiar with grasshopper I hope it will suit me.
Hi Tom -
Which version of Rhino are you running?
Kangaroo has been a part of the default Rhino installation for quite some time now.
I just saw in grasshopper that it is allready there. Now trying to manage it
aren’t there some sculpting tools for Rhino? I saw some video’s on YouTube where this is achieved very easily in Blender.
Hi Tom -
Not that I know of, no.
I’ve seen videos posted by someone creating a plug-in for landscaping that is like sculpting, but that is not yet made available IIRC.
for the crease part you can use loft, just make a few indentations where you would like them seen in curve nr1 in my very crude super fast rough up potato (not carrot :D), then nr2 and 3 for instance is then more neutralised. extrude 1 and 3 and use the resulting edges (not the curves) for the loft and use match start and end. mirror the result if needed (if the option match does not appear you used the curves instead of the eges) you can of course implement more curves if you want the creases to be less vivid as in my example.
