Need help with Modeling a Plaster Balloon Model

I have been looking into making this model digitally but I have been having trouble modeling it accurately. I made the physical model by placing plaster in a balloon and clamping it . I also tied string around middle to separate the pockets but the tie was relatively loose.


I was looking into modeling it in kangaroo with the pressure option but i am willing to use any parametric means. While the photos include images of a single module, I would ideally like to be able to model it with more than one clamp and multiple strings.

Hi ,
You can check out this two links there are some useful definitions shared

The example here could be a starting point:


The strings could then be modelled as extra stronger length goals on some of the mesh edges.

Hi Dmweekes1,

Did you succeed with the physical and digital models of your balloon structures? I am currently doing an experimental exploration of building inflated structures inside different containers, and researching how the inflates change according to the material/geometry/roughness of the container. I want to plaster the resultant form but I am failing… Could you recommend me the type of balloon and methodology for casting that you used?
And in digital, I used Kangaroo and it works for simple geometries. I would like to test more complex structures as yours, for example.
Any advice, recommendation or idea will be really really helpful! Thank you!!!
