Creating a grid from mesh to apply morph

Hello! I am struggling to recreate the paneling you see on the sphere onto the more complicated bird mesh. I have tried using weaverbird to get polysurfaces from the initial mesh, but I am looking to get a single grid I can use from these polysurfaces to then apply the morphed brep to. I am fine with having less faces (this would actually be ideal) in the final surface. Any pointers would help!

Mesh+ plugin has a component for making mesh faces into twisted boxes that you can morph into. It seems your complicated mesh has all triangle faces which might not get you the transformations you desire. If you need quads you might want to take the mesh into zbrush or meshlab and retopologize it.

Hello Michael! Thank you for your reply. I tried using the particular plugin you mentioned but I wasn't finding any tutorials on how to connect it to the rest of my file.

For example, when I assembled the components in an order I assumed would work, nothing seems to be happening past the twistedbox component:

You need to create the twisted boxes. See image below.

Thank you, Michael! I see I did not understand the workflow before. This is fantastic!

You use the M1 input of Mesh Twisted Box only if you want the boxes to be between two meshes (with identical topology). Otherwise you use the D input to offset height from one mesh.

Hi Michael,

I was able to get some great results from this, but I had one question. How could I make it so that the edges of the geometry would meet each other? Ie. I want to 3d print the object and have the faces on the edges of the bounding box meet. (See image for where these are not connecting)

As well, this proccess was pretty heavy on my computer so I attempted the same with a reduced mesh and offsetting curves. I am still getting the same problem however with the bounding boxes. Thanks so much for your ongoing help!

Wow, Panda! This is amazing and exactly what I was looking for! I have a question about the definition (as I am not familiar with these components) if I wanted to make each bounding box larger (and each 'tile' larger) how would I go about this? When I try to import a mesh with fewer faces it actually puts 4 tiles in each quad face!

It is because Panda needs to make your triangles into quads (via Catmull-Clark Subdivision) This is what I was saying before that triangles will give you not great morph results. This is Panda's way around it.

You should rebuild your mesh first!
