How can I close a big hole in a mesh?

Question

I have a large hole in a mesh that I'm trying to fill:

I've been trying an approach like this:

I'm finding it quite tough, since the number of vertices around the perimeter of the hole don't match a grid.

Is there a better approach to filling a hole like this?

Answer 1

Select the whole loop around the hole with Alt+RMB (make sure to delete triangles first). Use a Grid Fill option (press Space and type Grid Fill). Then play with its settings.

Answer 2

I think the remesh modifier will close this hole.

Answer 3

I made it this way:

1. Select the whole loop around the hole
2. Shift +D to duplicate
3. Scale the duplicate down (S)
4. Alt + Shift + RMB to add first loop
5. Bridge Edge Loops (space bar search)

and repeate untill the center and then collapse to center

Little work to be done but possible.

Answer 4

The Mesh seems to be fully triangulated, that means no quad based mesh, no edge loops... so I'd say no, there isn't any other way.

Last time I had that problem where I wanted to "repair" a mesh with bad topology I created some years ago, I rebuild the whole thing since it was faster in the end. Another idea would be to retopologize it by using the well-known methods.

Answer 5

I think it can be solved like this: go to edit mode, in the Mesh menu, click on "clean-up" and "fill holes"
