Smoothing rippled surfaces in 3D scanned files
Smoothing rippled surfaces in 3D scanned files
(OP)
I have a file that was created from a 3D scan. The file arrived as a clean solid body, but some of the surfaces are rippled. I can delete the surfaces and manually re-create them, but this is very time consuming. I understand that Scan-to-3D may have some tools that can help, but I haven't tried it yet. What is the best way to smooth out rough/rippled surfaces in point cloud data?
Thanks in advance

RE: Smoothing rippled surfaces in 3D scanned files
Can you isolate the ripples with a cylindrical surface, trim them out, and then use a surface fill to fill this hole.
You could delete the face alltogether and then attempt to recreate it using a surface fill tangent to the surounding surfaces. You may want to use constraint curves, so do the fill after the delete face.
Recreating the surfaces with lofts and sweeps may be the way to go. Ripples are often created when you do a loft and try to maintain tangency to the boudary surfaces.
Creating a loft or sweep on its own to recreate the surface, and then using extend surface on that surface and all surrounding will help you trim them to one another. Then use fillets to smooth out the edges.
Just some thoughts,

As for the surface fill, it seems that no matter how many constraint curves I add, the filled surface is very rippled and frequently has large protrusions poking out in-between the guide curves. That's why I usually break it up into smaller lofts. How do you guys get a smooth surface fill on a curved surface?
RE: Smoothing rippled surfaces in 3D scanned files
And as with lofts, too many guide curves make a smooth surface more difficult to achieve. Use only one or two (one in each direction--X and Y), making sure the curves themselves are tangent to the edge surfaces. You can also uncheck the Optimize Surface box when creating the surface to see if that helps.
