I'm wondering just how feasible it would be to have a tool that would make a 3D mesh from simple 2D mesh lines, like the photos below, or if somehow this can be recreated from an already existing tool, or in Blender for example.

Here you have a photo of a rock:

And then ontop of this image you draw mesh lines to the best of your ability, like shown:

In which if you take away the photo, you are left with this:

I imagine all of you can see some sort of a 3D shape here. Would this somehow be possible? Unfeasible? Let me know if this is the wrong forum to post this sort of idea.
