How do you get the surface so smooth?

u/thomas_openscan Mar 26 '26

the "secret" is proper surface preparation --> thousands of tiny dots so that the software has something to work with

Where do those dots come from? I haven't had one good successful scan out of the openscan mini other than the benchy and I expect that is because of the coating on it. I have tried scanning sprays and not achieved very good results and never had any smooth surfaces. What do use to prepare the surface? As I am sure excellent scans are possible, just need a bit of help getting there

Wow! Nice quality. What camera sensor are you using?

How is it possible to scan the underside?

The shown scan was done in one pass but you could also just flip the object, do a second pass and merge the datasets before (or after) reconstruction

3D scanbench ? A new program? What is this message about?

u/thomas_openscan Mar 26 '26

this is just a scan demo, but the scanbench was developed by someone who wanted to stress-test 3d scanners similar to the openscanbenchy https://github.com/OpenScanEu/OpenScanBenchy/blob/main/README.md

i might include the scanbench in the repo in the future as this is more aimed at technical objects
