Hi, could someone advise if there is a tutorial to create something like this in rhino/grasshopper?
Look up on youtube some Grasshopper Kangaroo tutorials. It will give you the results you want. Basically you set your base geometry, such as a rectangle with multiple edge loops. Then you set your anchor points that pull on that base mesh using Kangaroo physics. Then you can connect the pulled points to points in the room by creating lines.
Hope that helps!
