Sorry, it's revopoint not revoscan. It's easy to say the wrong one when all you see if the software day to day... I fixed my comment above. I'll try to get some screenshots up later today, but I've scanned lots of things with the turntable and I scanned my 21 month old when he was asleep on his beanbag.

Have you tried the reality scan app by Epic games? I did not get great results from the one scan I tried, but I've seen really good scans, and it doesn't care how fast you go or what direction.

That being said, as long as the revopoint keeps tracking: no errors. The only times I've had it lose tracking were when scanning a 1 2 3 block without spray (shiny metal) and when trying to scan my car dash in a fairly dark garage (high gloss black). For anything shiny and maybe very dark, you need spray of some sort; either the purpose made stuff or talc free foot spray.

The meshes can vary from mostly smooth with some bumps to kind of having a fish scale effect, but the later is from over scanning. Apparently you should always scan either one rotation on the table or only roughly 300 frames at a time for the cleanest result. You can convince as many scans as you want though. As I said below I'll screenshots of my results later tonight.

For 6" objects the POP line is perfect. For people or people sized objects the Range looks significantly better, but the range might struggle with 6" objects. I guess it's pretty common for people who get into 3d scanning to have multiple scanners based on what size you are scanning. The POP 2 can scan people, but you have to move a maybe 5x5 or 6x6 "window" around them to get all the detail. The Range had a significant larger view/window to scan people much much faster. The faster you can scan the less likely it is to lose tracking.``

I have tried a few of them without much satisfaction.

Same.

Its a shame because I know the technology is ALMOST there, but just not quite workable. I am sure some people have gotten good results, but still looking for a better solution.

If that is the only problem there are many solutions like this.

Most phone apps likely won’t reach the quality of a standalone scanner for a variety of reasons. For instance, a lot of the ones I’ve played with don’t optimize the shutter speed, which can wreck havoc when some captures contain motion blur.

That said, have you tried the free 3d Scanner App yet for iOS? Yes, you may need to clean up your scans like any other phone app, but since it also lets you use the front-facing TrueDepth sensor as well as the rear, it can return a pretty darn good scan when it can combine that TrueDepth data with the usual photogrammetry point cloud. Plus, it’s got a bunch of post-processing tools to modify your scans afterwards, like cropping out extraneous elements using a box or a sphere, selecting mesh pieces to remove/retain, etc. It’ll also export to SketchFab as well as your usual 3d printable file formats.

And no, I’m not affiliated with it; I’m just a happy user who was able to successfully use it to 3d print my doggo sleeping as well as scan some gallery exhibits.
