POP2 - PUTV 3D Models Showcase Progress & Tips

Can the mixture be with ethanol instead of IPA? IPA is not something you want to be spraying around in your work place - take it from everyone dealing with resin printing :wink:

As long it is alcohol, the point here is to evaporate quickly as possible .

Wow new updates in Revo Studio from April 24 finally allow me to align more complex models from 3 scans quickly , surprise surprise , we are back in business !

I was aligning half of top flowers with the main flowers plus the bottom of the small vase with the base vase … very fast and accurate . :+1: with the manual points , the alignment by feature still need some work .

Hi @PUTV

after reading and following more ore less the complete thread here. i think i have a good understanding now, how you work in regards of using Revoscan + additional tools, highly appreciate it. Thanks.
Will try that by my own.

Some questions still outstanding:

  • on each screenshot you posted for revoscan i recognised that you are still put the brightness to max. is that correct?
  • all your workflows to reach such good results are based on Turntable workflows. Did you tested full body scans without turntables? Because i think with a weight of 130kg its not so easy to use a turntable. i also would try to find a workflow to scan people without this turntable because i need also the possibilty to scan things without such a high effort to setup the location. and thats what revopoint promised in their full body sales videos.
  • Do you have ideas how to connect this led light
    REVO. VL Rechargeable Mini LED Light – Revopoint 3D
    with the revo point scanner? i mentioned in another post that the dimensions are not correct to fit.
  • Did you already experimented with cross polarization filters?
  • i also find it really interesting that you create more or 360° sections of your model with max 300 frames and merge it together in Studio oder Cloudcompare. This could work but in my point of view thats not how the software should work at the end. for me it should be possible to scan as many frames or round i would like to scan in revopoint. Revoscan should detect which points the already have. i dont like solutions to work with 3 other applications to come to a more or good result.

i am also a 3d professional but more in the CAD Direction. i also know a lot of tools to compare clouds, clean it and something like that. but for me POP2 was interesting, because there i thought i have everything in one place but thats not the case.

Highly appreciate also your tip regarding the AESUB Blue 3d SCan spray and the new markers.

it should be possible to get this at the end to an awesome result hopefully.

Thanks Markus
The brightness does not matter if you do not capture color data , you can scan in darkness , POP2 uses Infrared light so that really no matter , If I capture color data then I have to set it right .

I did not tested it since I am not seeing myself walking around with 20ft cables behind me connected to my PC, Smartphone option gives me only 1300 frames with my 6GB RAM and you can’t scan full body with this at once , you need to fuse the point cloud between and then hoping you tracking is working , too much hassle , when I do some outdoor scans of bigger objects I will let you know .
I try to make my workflow easier and not more difficult , I purchased POP2 for that purpose and I want to scan full body at once in a single run as quick as possible , nobody will stay still until you finish scanning and fusing , it will take too long time, your model will get bored and move, then you will have to start over again , this is different scenario for scanning heads , or faces as I did this already without turntable .

Sorry I am not using this type of lights , mostly I scan inside my photo light box , but I will need to set up some light for scanning outdoors , but right now not even into it yet .

I do it for my work and actually I was going to attach polarizing filter to the RGB camera and see if I can reduce the reflections on some objects however polarization filter works with reflection from different angle that my light box provide so not much usable , however may be good for scanning outdoor in color mode , however the textures are not much usable for my work . I use them only as reference .

That is how you should scan 3D models , and for that reason you have Revo Studio , nobody scan 3D models in one run , you will get plenty of overlapped point cloud , Revopoint also do not recommend over scanning over and over again the same regions , not good workflow , sometimes I do if I have simple object but for more complex , this is no no .

Revo Scan is not a magic button , sometimes it works , sometimes it doesn’t, some objects can be scanned, others need more than one scan , it depends .
I use POP2 to capture my 3D data and working just in Revo Scan do not deliver for me what I need as the meshing is too low , and there is no option to clean overlapped point clouds , I only export my point clouds and that is , I do here some previews for the showcase but for professional usage I don’t .do everything inside Revo Scan .

If they merge Revo Studio with Revo Scan then there would be more possibilities in one software . There is no one scanner in the world that can allow you to do manual scanning and provide top results. These things don’t exist , that is why 3D scanning services are so expensive, it takes time , lots of time .
POP2 delivers what I expected and it saves a lot , for my hobby or work, it is just perfect ! I hope the software improves with time , it is still a baby , new concept and new design . If one day there is a 3D Scanner with one software that delivers everything at once , then I will have to look for another job 😂 , but that will be no more fun anymore. I love to create and automatic duplication will not drive me anymore or keep me creative , in short very boring .

I am sure once you get more familiar with it you will get great results and have really fun creating , since you are already familiar with 3D I don’t think it gonna be hard for you .

Best Wishes

[quote="[Tutorial] Revo Scan | Revo Studio | Bonus: Quick cleaning and meshing in Cloud Compare, post:1, topic:12918"]
Here is the new tutorial/workflow recording
[/quote]

I notice in your tutorial that you removed overlapping points in two different sequences: early on, you moved the slider from left (Near) to right (Far) as you deleted points but, at 3:26, you went from Far to Near.

This seems counter-intuitive to me. Do you have any tools that demonstrate that either sequence provides equivalent results, or are you just eyeballing it?

Jeff , that really no matters what direction you going , the settings are pre-programmed , so if you use the near first or the Far , both has nothing to do with each other , what matters are only the distance between the fused point cloud and lose points that never fused , you doing it until you get message that there are no more overlapped points , but that is also not true , there are lots of overlapped points even after cleaning in Revo Studio , as you saw I imported the “cleaned” mesh to CC and still had a lot of stuff to clean , what resulted in less noisy mesh after wards . The Alignment in Revo Studio is very raw , maybe 30% accurate , there is no point cloud registration function for very fine alignment , that why I had to clean it each time after alignment . I still prefer to do that quicker in CC , unless I have a simple mesh to deal with ( without alignment )

There is no way to even check the true state of the point cloud in Revo Studio , removing the lose points did not worked as well , but at least I could align and merge the scan data what is already improvement since last update .

My first use case is to mount a rear bike rack to a rear suspension bike

. I have the rack bough online(blue lines) and it also has a slide lock folding trolley aka “it’s worth the effort”. The problem I ran into is the mounting brackets it came with do not fit the bike frame. I kind of expected this will be the case.

What I want the pop 2 to do is to scan the orange area on the photo and throw that in 3d design software like iOS shapr3d. I then hope to design a 3d printable bracket which would for my purposes be of excellent? fit.

Seen videos that show 3d printed mold used to make carbon fiber parts and that’s what ultimately I want to attempt.

In this use case I can take the wheel off and be left with just the frame to scan by hand.
I can see that in the right hands as shown in this thread Revpoint pop 2 gives excellent results.

@PopUpTheVolume
Is the sort of thing I described attainable with this 3d scanner ?

My desire is to have a good workflow that allows me to buy a product(s) that with a bit of shaping in 3d software like the bike frame use case can be combined even if there was no foresight for this at the point of manufacture.

The other option is Einscan Pro 2x plus with color pack. The obvious problem there is the price of several ££££.

Hi @PUTV, thank you so much for sharing your awesome results and tests.

I just followed all your tips and ended up here in just few minutes.
I still got a lot to figure out but i learned some facts:

  • the pop2 rocks (great job @Revopoint-Cassie)
  • a good set-up is half of the work (as in every situation :slight_smile: )
  • the learning curve is not that high
  • still no way for textures in revoscan :frowning: (waiting for your z-brush workflow :smiley: )

here were i ended up (face mode+revoscan+cc)

and were i started

thanks again i’ll go on with experiments

Hi @Dax I see you got yourself the same Light Box that I have :+1:
I am surprised you got this scan using just face mode , considering there are not many features in that flat object , the details are nice .
You know I tested some stuff on fabric , and with my smartphone I could capture the threads on the cotton using feature mode , but on my PC I can’t . I wonder if it is the point cloud fusing or alignment better on Android than in Revo Studio .

In CC you could cut off the extra geometry , it is happening when the model is not fully scanned top and bottom , CC thinking it is terrain lol but the results are nice Daniele.
I was thinking of getting myself a transparent plastic mannequin bust to scan clothing .

Yes the textures do not always , especially if there are overlapped points, but I tried to clean the original fusion files from the project and used the batch converter to produce better results with textures .

For the Zbrush workflow you will need to scan the object in color mode and not generate textures , save out the scan data after fussing and or meshing as *.ply or *.obj to extract the textures later in Zbrush . I will work on the tutorial today .
You also will have the option to use Cloud Compare to clean out the model but for texturing I prefer to have as many points in the scan as possible since each point represents a pixel … You will see in the tutorial .
The texturing that is happening in Revo Scan after meshing is a different process than the RGB color per vertex , it is photogrammetry based so each picture POP2 is taking is overlapped 30% on each side , so if you over scan too much you may ends with different colors of the texturing parts, or it lands somewhere else it should , sometimes it works sometimes it don’t .

I once extracted all the images data from the Revo Scan project and used the pictures to create models in Meshbox , it was a perfect replica of the scan .
So POP2 has the ability to capture ideal photos for photogrammetry that are linked to each point cloud frame for the texturing process .

My original intention of purchasing POP2 was for human scanning and capturing 3D normals data for my work to extract it into normal maps that can be used later as Zbrush 3D brushes in my modeling work .

Here some point cloud tests for capturing the data for normal maps, I was surprised how much more detailed the point cloud fusing was on mobile compared to Revo Scan on PC , that was single 300 frames capture . One slide , looks to me that the point cloud fusion on smart phone has better alignment or higher resolution , and it was hand held .

I have very detailed figurine , I will make 2 scans with PC and Smart phone on turntable to see the differences .

I found a bug in batch processing inside Revo Scan Win , it does not create UVs for the model , only textures , fuse and mesh . The UVs information is missing , also no MTL .

@Dax as you wished , here is new tutorial for converting RGB color per vertex to new textures in Zbrush

Hi @nick-mesh I just saw your reply right now for some reason was not visible all day long , yes you can do that , but you will need to prepare first the surface for scanning , meaning 3D scanning spray or home made solution I mentioned early , the black paint will prevent you from scanning anything , that why it needs to be prepared , you could scan both sides at once , or each side separate and merge it later in Revo Studio or Cloud Compare for better accuracy , it should be not difficult task to do for POP2 .

Dear @PUTV thanks for your new tutorial (that quick!) i’m gonna study that :wink:

Yep good set up = less work

My goal is to create some clothing assets to populate some of my cgi jobs, so i got a lot to figure out; this one shirt is the first decent test, but i wanna try more. If i can get good normal+good diffuse that will be great!

I still haven’t try pop2 on my mobile, i’m bit worried about alignement; but your tests are impressive.

i’ll test and re-test to find the smoothest workflow :wink:

thanks again

Scan for today is Athena figurine

I tried to scan it all at once inside Revo Scan and also mesh it inside Revo Scan , and guess what? I succeeded . Scanning full object at once with 3000 frames may lost some details , but I am going to make comparison , between scanned this object at once and using just section for merging to see if I get move details this way , scanning just 300 frames per rotation or 3000 all at once , until then here first test .

The figurine is 170mm tall , it needs at least 3 section to be scanned partially and one from top and one from bottom so 5.

Not bad for full inside job , not even overlapping

Some little showcase video of using just Revo Scan , no processing, no merging , no alignments , no tracking markers , how easier can it be …

Hello, what I don’t understand is that in the “depth camera” window you almost never have red “overexposure” marks? (only at the end of the scan, some red marks when the camera is on the feet) I still have these red marks, although I am with the gain at minimum. How do you never have red marks? I updated to 4.01.0417b. On the other hand, I never have blue marks…?

Have you been preparing the objects with a 3D Scanning spray (or even dry shampoo)? That will minimize overexposure.

A possible cause of the overexposure is an infrared light source in the room (possibly even a heater) or it could be as simple as an incandescent light bulb providing, seemingly, very little light, but still too much.

Thanks @PUTV - this thread is very encouraging and exciting :relaxed:.
I’ll start with the powder method before considering the spray, either way this is just ultra fun thing to be able to do :joy:

Been monitoring the 3dscan to 3d print communities for a long time. 3d scanning on an OK budget was the roadblock until revopont pop 2 came out. Now the ‘toolchain’ : reverse engineering to modify to home manufacturing is so much more realistic.

If anyone else is on the same path
here some of the best ways to produce carbon fiber part from 3d printed molds(after 3d scanning) Make Forged Carbon Fibre Parts Using Compression Moulding - YouTube
It’s a big catalogue there with more CF videos.

It will be a few weeks before I get back to this thread but I hope to post a nice success story like yours @PUTV :grinning:

I really like this thread and the pop 2 :relaxed:
