I'm attempting to create a mesh from a flat png image which contains only the shape I intend to create. Following various guides online I was able to come up with a solution using a grid node, but this makes the mesh pixellated and rough, messing up the shading even with shade smooth on.

Geometry nodes setup.

This also results in the object being very intensive to render and manipulate/animate, because to make even slightly smooth I need to have the grid resolution very high.

Mesh from geometry nodes.

Mesh after some manipulation to create peaks.

So my idea is to create a concentric low poly mesh from the shape instead, as per this very fancy illustration I made, and to then subdivide it from there :P (I don't know if 'concentric' is the right word but I mean so that there would be vertices running through the centre of the shape, with subdivisions

Diagram explaining my idea.

I haven't been able to find any methods of creating this however, and I'm out of ideas. Can this even be done with a png and geometry nodes setup? or would I have better luck working with svg shapes instead? Any advice or pointers appreciated <3

  • $\begingroup$ Your solution to the problem is an even bigger problem. It's better to smooth the grid mesh. It will shrink it, but you can calculate area before and after and move the boundary edges away/towards their faces to fix the area. $\endgroup$ Commented Apr 23 at 17:19
