Hello
what is it you want to finish ? It seems more you didn’t begin?
From the limited explanations, references … it looks like a sort of physical simulation of glued 2 surfaces that are moved.
There could be way to make some approximations using isosurface, or some kind of minimal surfaces …
So could you elaborate a bit more? What are your inputs, outputs? Do you want a dynamic results, a static one?
Is it that you are after ? “sticky gum simulation”
Follow the last tutorial.
Make a planar mesh.
Extract some inner holes
Extrude the holes (Pufferfish has a component for that)
mirror the shape
smooth the shape (I used Smooth from Ngon)
Sticky sole! cool concept for keeping dirt like a lot of lattice concepts.
