Mesh or 3D scan to highly detailed Nurbs to retain fine details?

Converting mesh models to nurbs has been made easier with subdivision surfaces, but what if you don’t actually want a super smooth model… what if you want to try to keep as much nitty gritty details as possible, regardless of how heavy the surfaces become?

I just had a quick chat with the person who does our 3D scanning and the software he uses (Polyworks) has some functionality for that we can test, but anyone else have any other suggestions?

The only other thing I’ve found so far are some obscure software called Cyborg MeshToCAD, Autoshaper and Resurf, while I’ll see if I can trial (but at least Resurf I’m 100% certain will produce a too smoothed out result for our requirements).

EDIT: Found Mesh2Surface now too, but I’m trying to get away from subdivs… what I need to get into nurbs is highly detailed… think, tree bark and things with similar detail… or like a brick wall with the porous masonry at least somewhat intact… it can’t look like a used bar of soap after the process…

did you try Rhino’s MeshToNURB? that would create polysurface with a surface for each polygon, it definitely can get heavy. also why is that in Meta?

Pardon me if this sounds ‘pedantic’, quick question: when going from mesh to SubD, there are options in the command to pick from - these can help retain or omit certain qualities from the original mesh?

Also when remeshing via QuadRemesh (before SubD, if this is an option) you can detect hard edges?

Unfortunately nurbs does not represent high frequency detail. Your soap bar analogy elegantly describes the problem. The nurbs surface is interpolated … you won’t get nitty gritty.

You should use a mesh instead if you need those details.
