Inflatable structures

Hey guys!

I would really appreciate it if anybody could help me with the fallowing image. I have been working on inflatable structures and checking out different parametric codes. Usually simple designs will perfectly worked with gh codes, but I am trying to add multiple holes just like in the fallowing attachment. What might be the best way to start modeling for this sort of designs?

Thank you!

This inflatable raft is flat and not like your object wrapped around something but it could be helpful anyway…

Thank you for the response! I will definitely check the code. But yes, the wrapping part is one of my main concerns.
Thanks again :slight_smile:

What do you have so far? If you can’t get it to work, post files please.

well you might not need grasshopper for this, but i usually advocate against grasshopper since for simple things like these its just overkill and kills more time than it helps.

here i tried with a few cubes in a checkerboard pattern give them some overlapp, then use the command ShrinkWrap (new v8 command), i would skip the optimisation, and set the edge length to something smaller till it connects nicely but gets boxy. then use the option smooth which will round it up again then use FlowAlongSrf and flow it up a truncated cone. i would actually use FlowAlongSrf first before you ShrinkWrap, then the shape will be continuous, here i did the wrap before the flow but well i will not change that now. . you might wan to think about reducing the upper amount of blocks since you have a shorter circumference there, but i leave that to you. setting up the exact same (nearly the same i believe there its called morph instead of flow) stuff up in GH should not be to difficult either.

Thank you, your reply is really helpful! I tried to do modelling according to the steps you follow. Changed the distance between in the pattern etc. My question is, How did you get that inflated effect?

What do you think about FlowAlongsurface command running with polysurfaces, meshes or Subds? I want pattern to go around the pillow shape.

polysurface without grasshoper plugin will not be possible, subd the same. but you can create 1 warped surface by hand, make a plane change degree to 3 for instance then take the 4 inner surface points and pull them up, flow it along this surface, use Mirror on the result and shrinkwrap it.
