Hello PUTV!

Thanks again for sharing all your work with the POP 2 and now the MINI. I love how much more details the MINI captured for my 1/6 scale headsculpt!


Just wondering, do you feel that the MINI is harder to use compared to the POP 2? I find
I had no issues resuming scan when I reposition the objects with the POP 2 but with the MINI, I kept losing track multiple times and only got this successfully when I first scanned it laying down then upright (rather than upright then laying down). Is that the nature of blue light scanning or is it something wrong with the prototype I received?

edit: Just read the guide you wrote for johnchen and it was very enlightening, thanks for sharing your expertise!

Thank you @zedabyu , BTW I love your YT channel ! keep up the great work !

Yes it is incredible how much improvements MINI offers compared to POP2 with small objects .

Yes I experienced the same thing , even in my tutorial about Android phone , the bunny lost tracking when started uprights and then on the side , but not when I started from the side first , I think it has to do with the nature of the object and the angle of MINI to the object , the angle was too narrow and the sensors could not find the features while it was on the side , once I moved MINI up a bit it quickly find the tracking again , so definitely the angle , with the upcoming Revopoint Dual axis turntable things going to works so much better and flipping the objects will be in the past to some degrees …

When you scanning your mini figurines , try to keep the proper distance , I actually use a chopstick where I marked 10-15-20 cm for a fast and proper distance measurements , it works all the time :wink:
Yesterday when I tried to scan the pin I used distance of 10cm , the Depth Cam Preview was kinda blurry at the distance but the scan was shocking detailed as never before , small objects need to be as close as possible to capture the micro details what in this case is 10cm/100mm and moving / rotating , not shutting frames while the object is stationary like with a camera as it will create a lot of noises later. MINI is also more sensitive to shaking , at that accuracy and resolution, too much shaking will mess up the point cloud frames and that is normal , any other scanners at that accuracy and resolution are never portable and very much stationery for capturing the best details possible.

Love the previews here, I told you before , MINI gonna do the work you were looking for and the images are worth a 1000 words , however I also love what you did with POP2 in your video "Doctor Strange Theme " , it was a good one .
Keep up the great work ! and thanks for stopping by !

Oh thank you so much for watching the video!!

I love your tutorials as well! Professionally edited and perfect for a lazy person like me who wants to just get the results without doing all the testing :stuck_out_tongue:

Thanks for not holding back when sharing your tips and tricks! I am going to have to refer back to this thread when I attempt to scan again, definitely trying the chopstick trick :face_with_hand_over_mouth:

@zedabyu thanks ! I can say the same about yours . Your videos has a great editing and flow , I am glad you got your hands on the beta MINI , well deserved ! Looking forward to see more of your pro creations and scans. And thanks for the refer !

Scan for today , nothing special but I tried some new things with merging , and came to conclusion that scanning stuff with POP2 and then adding details by scanning and margining with MINI to it do not really works in practice , first of all POP2 accuracy is different so the volume is not exactly the same as MINI’s , there will be a seams between both of the parts that need to be cleaned manually in modeling program . So do not works in Revo Studio . Other programs have very fine point cloud registration but Revo Studio have more of a raw merging functions . I think it is just an extra work .
What you would work if you can scan with MINI at pitch point 0,1mm and then details at 0.02mm then you have both scans with the same volume accuracy and it would works much better in practice.

However MINI is so sensitive to changes in distances so if you scan at 20-25cm and details at 10cm , you will have a huge differences in details in both scans that will not merge proper and smooth.

3D Scans at 20-25cm what is the maximum distance , I simplified it to 250K in Revo Studio

After I scanned the battery last time with MINI, me and my son have some DIY project and printed it out and my son painted it and made a keychain with mini screwdriver for his father. I think it is cute .

Happy Father’s Day Weekend !

Your son did a great job painting. Happy fathers day.

I see the theory of scanning with POP2 low base and adding high details with MINI is growing and everyone saying yes yes yes but nobody actually showing the workflow how to do that , and if you think that you can just scan low base mesh and add just high resolution parts with MINI and problem solved , not so fast . Revo Studio do not works this way and you will be never able to do that .
What I did in Cloud Comoare is a different scenario , so here is the adaptation for Revo Studio .

Trial and error and theory in practice and actually the proper workflow for that using Revo Studio.

1. The failure, and what you should not do

you loaded 2 models , one was full scan with POP2 and one was a partial face scan with details you wanted to add to the base .

The left is MINI and the right is POP2
you used feature mode for merging and hit the button

You got merged object and happy it worked, no it did not worked as the model is still POP2 and not one point was added

Point cloud view

Then you thinking maybe adding manually the trackers will works

No it do not works
still the same old POP2 scan without any point added

So that is all about the theory for adding high resolution fragments to low resolution scans in Revo Studio

2. How to do that proper in Revo Studio
The process

First you going to load the low mesh to Revo Studio, and cut off the regions that you need to replace with high resolution parts
The left is POP2 with cut out parts of the face that will be replaced leaving some overlap for matching the points with the fragment of MINI scan.

Then use manual marker mode

and hit the button for merge , now you see the new part was added to the lower resolution mesh
you can mesh it now at 6-7 value

Now you need to remesh it , in Revo Studio the option is under Simplify
set the mesh values as you please , it can be still be the same value as before , how the decimating function is working?, it freezes the edges of the mesh , and equalize the surface . So actually it is a decimator and not simplifier , this going to be also very helpful , I find that using around 250K for organic models works always great , so maximum 500K is more than enough , however if you want to preserve everything you can leave the value almost at the same number , but you have to change the value slightly .

Now the mesh is equalized keeping the point density only where it was needed keeping the details sharp , but reduced overall for less data that was not really necessary in the smoother areas.
as you see the density is only on the edges where it should be

And the model is ready for export with all the details you wanted at 250K only .
If you work with mechanical parts , it gonna be very usable for your reverse engineering workflow as all you need are the sharper edges as references.

I hope this going to be helpful for everyone and is more clear how to process it in Revo Studio.
If you have any questions please let me know .

thank you for the detailed workflow on merging scans, can I ask, what if it was merging multiple scans from MINI, should one cut out the areas where the overlap occurs when merging two different mini scans?

Thanks !
I just posted video about that above your post .
You actually should cut out parts that overlapping too much , not everything going to fuse after merge , What can results in uneven mesh and need to be cleaned before meshing .

Cutting out parts will deliver better point cloud registration with MINI , since it has higher resolution , you will cut down on errors and overlapped points, and processing time , since Revo Studio is not yet on that level compared to other programs like Cloud compare or Meshlab .

I do not use Revo Studio for any of my pro work . I use Cloud Compare , but for beginners Revo Studio is much more simple to handle and you can still get good results with less hassle.

So I don’t understand…! in “revo scan” you do not save your scan in .ply (points) but you make the mesh and save in .obj (or .stl) and once in “revo studio” you import your meshs (.obj) for transform them into a point file and at the end re-mesh them again??? it’s a bit crazy isn’t it? why don’t you simply import the “non-mesh” files into Revo Studio???
