Wrapping a 2D net over a 3D object

Question

Is there a way to have a 2D mesh wrapped around a 3D object. Like this:

The red part is a flattened knot, which I mapped onto the surface of the blue part. In this specific case I used math to achieve it, but not all shapes can be easily expressed as formulae. What other ways are there?

I tried using physics, making the blue part a passive rigid body and the red part a soft body falling onto the blue part, and it seemed to work beautifully. But when I tried it again now, I realised that it doesn't do what I'm after. The net and the object onto which I want to wrap it already have the same X and Y dimensions, which is how I want it. I only need to remap the Z coordinates.

Another idea that comes to mind, would be generating a texture from the Z coordinates of the blue part and use that texture with the displace modifier on the red part. Is this possible?

Answer 1

You can use a conbination of Mesh Deform and Cloth simulation with proper settings.

• Create a grid plane to cover the whole net;
• Add Cloth Simulator to it, then Solidify modifier;
• Tweak settings of them;
• Add Mesh Deform modifier to the net object. (use higher Presision value if necessary, then Band)
• Then play or bake the final shape. Delete the grid mesh (optional).
