Fill a hole with a new vertex and then triangulate
Fill a hole with a new vertex and then triangulate
Hi have a mesh where each internal vertex has 6 neighbours. However there's a hole in the mesh I'd like to fill by creating a new vertex and then join the 6 closest neighbours, see picture below. Any suggestion how I can do that?
Basically I want to pass from a situation where I have the stuff in the red circle to a connectivity like the one highlighted in green.

Fill and Poke
Select the perimeter vertices (or edges) of the hole.
Fill with an ngon F
To start off, select the perimeter of your hole with the edge select tool and move your cursor to it by pressing Shift+S and selecting "Cursor to Active".
Next you should select a similar set of triangles that will fill the hole:
Next press Shift+D to duplicate the faces and move them somewhere so you don't have overlapping vertices:
Next, while you have your replacement faces selected, and your 3D cursor in where it should be, Press Shift+S again and select "Selection to cursor (Offset)".
Finally, after you have everything in place, select the whole mesh with A and then press W to bring up the Specials menu and "Remove doubles".
If it doesn't remove any vertices, try turning up the "Merge Distance" value a little bit.

True, there are faster ways, but this method can be really easily scaled and has methods that can be used in other situations.

Alternatively: After you select the edges fill (F) will make an ngon face which can be poked
