# Geometry Nodes Displace Grid On Curve

I am currently working with geometry nodes in Blender. I have a circle edge loop that needs to be gridfilled.

I currently have a seperate grid. The vertices inside the circle equals to the vertices on the outer edges on the grid and I would like to displace all the vertices so that they fit inside the circle. Can anyone explain to me how to achieve this?

• Do you want to create a subdivided cylinder? i.imgur.com/sj8xqqs.png i.imgur.com/iQq83mK.png Sep 23, 2022 at 14:45
• Thank you for your comment. I am not trying to make a cylinder, I am trying to fill the circle on the left with a grid like structure Sep 23, 2022 at 14:57
• Do you know about the "grid fill" operator? i.imgur.com/MYKSs3D.png Is this what you're after, or do you want to just carve out a circle out of a grid? i.imgur.com/N7bLTRD.png Sep 23, 2022 at 15:41
• Hi Markus, Yes, I am after the gridfill operator! It is available in normal blender, but not with geometry nodes Sep 23, 2022 at 15:52
• If you look here, you'll find a 'Grid Fill' GN group which follows the Grid Fill operator very closely, and will fill your circle exactly as the operator does. Sep 23, 2022 at 17:34

You can use the 'Grid Fill' GN group from this answer to make the transition from grid to circle, or any other shape with the same vertex-count in the perimeter:

(Depending on what you need, you could expose the Mix factor to the interface of a regrouping of your own)..

• Thank you. I tried to implement it myself first but failed, after i just copied that group it worked Sep 23, 2022 at 18:54

Maybe that simple trick could do...

• Well this does seem to give the right shape, although with this grid I do not have the right amount of vertices. How would I connect this grid to a different circle then? This grid is in the middle of the scene, like the one in my picture, but i would like to know how to connect these properly Sep 23, 2022 at 16:15
• In my opinion, it would be something like my edited answer

• It's defenitely a step in the right direction, although for me, all the vertices seem to go only to a few places on the circle, so it's not really working properly Sep 23, 2022 at 16:47
• FWIW, the vertices connect like a star Sep 23, 2022 at 16:55
• While this seems to answer the question, perhaps you could add some details about how/why this works as a solution. Sep 23, 2022 at 17:19
