Any ideas on how to make this?

Hi All,

Trying to make this, any ideas of how this could be done in Grasshopper?

The product is a mattress, that is made by extruding a thin bead of molten plastic into water causing the bead to freeze not long after its has laid onto other bits of bead, the end result is a soft spongy very porous rectangle. I would be keen to make this in varying thicknesses so would probably have a bounding box as the constraints for is boundary.

Thanks,

Ma

Does something like this work for you?

Here is my approach:
sqcp-a.gh (20.3 KB)
sqcp-b.gh (9.3 KB)

“sqcp-a” uses Kangaroo for a stricter inclusion in a container.
“sqcp-b” is a lot simpler, but beware that both of them take quite a bit during the meshing phase (that’s why I’ve disabled those components).

Thanks Sub, This looks superb!

I just tried to import your ‘SQCP-’ file into GH but I am missing ‘Mesh Pipe’ plugin, I assume I can just substitute this for the Ngon’s version (which I have installed):

Cheers,

Actually, all I need as an output are the splines, because I’ll just export these to 3D Max where I can render them in software. So I guess I could just generate with the splines?

sorry about that… unfortunately I don’t remember what plug-in has that MeshPipe component.
I’m not familiar with the NGon version, but as you say I guess the spline export to 3dsmax is the easiest way.

You could probably also use Multipipe instead of mesh pipe

It could be from MeshEdit, but Martin is right. It’s probably better to use Multipipe, unless you want to deal with lots and lots of mesh Booleans later.

Martin, Diff and Sub,

Thanks so much for the help, replaced the mesh pipe for multi-pipe and ended up with some lovely SubD shapes!

Looks great.

Just a quick q, and i’ve read on some other threads, but I was trying to remove the ‘placeholder’ for the ‘mesh pipe’ function, but couldn’t seem to do it. In the end I had to rebuild the above in a new scene, which was great for my learning anyway, but was wondering if removing redundant placeholders has come on any further?

Thanks,

Marc

Couldn’t resist putting a silver environment map on… lol

I usually select everything else and copy it to a new file.

Hi Marc -

There is a plug-in somewhere that lets you do that. I don’t believe David has any plans for doing that natively in Grasshopper 1.
