how to build a shell mesh out of lines

Hello peeps,

I have got these lines here reconstructed from a scanned shell. how is it possible to build a clean smooth mesh out of these lines? i have tried using sweep and crv network but nothing worked out properly or it looked as if it multiple pieces stitched together instead of one continuous surface/mesh, i hope you got what i mean, your help would be appreciated, thank you.

kind of but it is too deformed on the other side. i believe you have sweeped and smoothed the mesh right?

I am looking for more of a relaxing mesh technique more than building from lines in rhino.

I used crv network then rebuilt surface

In general:

(a) if you have a directed graph (in 3d space) where each node has a valence <=4.

(b) if the graph has a suitable topology (a very big issue that one: meaning that if garbage in > chaos out)

... then you can build a mesh using connectivity Trees (like the ones made by Sandbox) and most notably VV and EV,VE ones (V= vertex, E = edge). This approach can build a Mesh (with quads or triangles) "as it is" with no relaxation and the likes.

I have several similar examples but using solely code. Notify if you think that a similar demo could be useful for you.
