Starting off with 2 auto-turntable scans in feature mode. 3 passes in each scan, each pass at a different angle for 111 total frames.
Tracking was excellent for feature mode, no frames needed to be discarded. My only complaint is the RGB camera controls are nearly worthless, which is why Anya and Bond are a bit on the warm side (I didn’t do any editing outside of Revoscan).
The RGB camera has a fixed focus at about 300 mm. I don’t know why that is, probably because of the calibration? But in any case, unfortunately, the distance must be maintained if you want sharp photos.
Interesting! Funny enough, I was testing some Warhammer miniatures and the RGB camera was unusably soft.
I have recalibrated since then so I can’t compare that experience to now unfortunately. I’ll retest a miniature but at a glance I think you’re right. 300mm is the center of focus, and depth of field is maybe +/- 50mm. That would mean for sharp textures, you should aim for the center of Good on the distance scale, which seems counter to all our past Revopoint experience.
I suppose that might make some sense. Why would the distance scale with 5 divisions have 1 division on one side of “optimal” and 3 on the other side. Of course I’m interpreting “Excellent” as “optimal” (understandably I think).
The RGB is calibrated with the Depth sensors so it can’t have auto focus .
The sharpness is not matching the distances indeed.
My device sharpness start after 250-300 as well . So if color is important it need to be captured in the middle of excellent| good distance
I use color calibration card to calibrate the camera then set it to manual .
Also using a LED lighting with at least CRI of 85-95 will produce brilliant colors .
Here are some old Warhammer miniatures in autoturntable mode. They are ~25 years old, pewter, and painted by a much younger me. So maybe not as detailed as a fresh new one.
The base of each character is 20mmx20mm for reference. Applied some lighting and metal enhancement in Nomad, otherwise what you see was what was captured.
Some of my daughter’s Schleich animals. Auto-turntable with marker tracking. Textures and geometry all straight out of Revoscan with lighting and rendering in Maya.
One of these elephants was scanned with auto-turntable, the other with crossline laser. I transferred the UVs and texture from the auto-turntable scan to the laser scan. Which is which?
My thoughts are the laser did a better job on some of the deeper, harder to access features, whereas the broader areas show more definition in features like the skin wrinkle with auto-turntable.
It was a very hard quess , you did really great job with the laser scan, almost invisible differences what is fantastic , guessing from a picture almost impossible.
The level of the details on the objects are very good in comparison including the color data.
Yeah the Auto turntable mode uses different technique while scanning than the Full Field or laser mode so it require all angles to be captured well and if possible at the same distances possible for the best result , even 10-20 mm distance could make big difference in final results so good planing on the rotation steps is important to get the full exact results at any angle .
With a lot of blind spot on that object it can be little time consuming to find the best angle.
But you did really nice job on it.
Not to mention it is probably resin or plastic material with acrylic paint .
