Anyone have any experience with modeling a tufted look?

I'm trying to figure out a rapid way to model tufting on sofas or chairs.

Would be just for rendering purposes, but a texture of tufting isn't going to cut it..

I attached this diamond pattern here just as an example..

Thanks in advance.

Hi,
Once I modeled a chair with such a tufted back. I modeled a chair with Shark and quilted upholstery with mesh modeler(in my case Silo 3D).
If you do it for visualization(renderin), then zBrush+MeshEditor combination is ideal for such tasks.

The VC/Shark does not have suitable tools for this. Shark's Mesh Tool is too poor. With Net Surface is probably possible. But I don’t think it will be easy. In addition, this is diamond-shaped pattern.... :( Difficult!

The most likely option is a normal surface modeling. But it will be long and difficult too.

What about the "Pressure Deform" function ? by creating a surface to a defined boundary and apply
a pressure, one has to try different "gain" values to obtain the desired shapes.... just my 2 cts

Thanks! I only need it for rendering/visualization. I thought about using surfaces but it seems really complex as you've pointed out. I wish the mesh tools were a bit easier. They do have so much potential considering theyre conveniently built right into the program.

Awesome suggestion – thanks Garlic! I also thought about "Insert Knots" to the surfaces to push/pull various areas in and out.

Could you please explain how to get started with this method? Or if you could point me to an existing tutorial? I am not certain how to get those circles to connect to the Net lines. Thank you!

If you are using V10 do you still have the deform face tool? Would that work?

Yeah I'm using SharkCAD v10. It has Pressure Deform, Curve Deform, Point Deform. I don't see a Face Deform... maybe Pressure is it?

THanks!

Here's a short video with a basic diamond mesh. For a better result, you will certainly need more splines.

Quilting like this is an array of a thing called a Gregory surface, this one's done in Marcus Bole's PolyCAD program, very similar to pressure load, although the curved edges between the tufts are trimmed in from the edges of a Gregory, which are flat. Pressure load is Deform Face in SCP V10. Skin surface or solid with a symmetrical curve between two lines looks the same, too. Overlap the array, there's no need to try to meet edge to edge.

I often watch Arrimus 3D tutorial channel. There is one interesting tutorial: "Tiling Sofa Geometry" - https://youtu.be/fFSVUbHuHB8
This is of course another software. But the principle can be used easily in any other software.
