Hi everyone and welcome to my MetroX Showcase , my name is Cath aka PUTV and I am Revopoint’s independent Beta Tester for products and software for the last 2 years, I have 30 years experiences in organic 3D modeling and 3D scanning , for that reason my showcase focuses mostly on organic objects and scans , opinions as always are my own .

NOTE : All Scans in my showcase were captured using various Beta Prototypes of MetroX and its Beta Software. and not using the final Public Build . The results for that matter may be not optimal or final .

SCANNING SENSORS

SCANNING MODES

MetroX include 4 modes for various scanning options .

Full Field is a optimal Structured Light scanning technology with 62 limes that allows you to capture objects with rich details and features, objects that are hard to replicate using 3D modeling , however it also have marker and Global markers option to scan objects with less prominent features and still keep the good tracking . Full Field mode is very fast and you can use single shot mode or continuous mode.

Auto Turnable mode also uses Full Field and have RGB color scanning option .

14 Line Cross Mode is a Laser scanning technology , it requires to use markers , this mode is for scanning any objects but preferable objects with less features to preserve the accuracy , sharper edges and corners . it is great to scan bigger and flatter surfaces like for example a car door . Laser modes are slower from nature and requires a little more time while capture .

7 lines Parallel mode is a laser scanning technology same as Cross mode, but only uses 7 laser lines for scanning , it is great for scanning smaller objects with less features as well or with more detailed . It preserve all the cavities and edges on your scanned object . As Cross mode it is most time consuming mode because it has only 7 Parallel lines so you have to spend more time moving it across your object to capture all the points .

STRUCTURED LIGHT l FULL FIELD SCANNING MODE

Full Field scanning mode is more familiar to you because all previous Revopoint Scanners use Structured Light technology with Full Field mode , MetroX just use Blue Structured Light technology as one of its mode and is very similar to the one used by MINI series but with 62 lines and bigger FOV , the Blue SL is also much brighter and can capture much easier materials that are dark or metallic so huge improvements from Blue SL used by Mini Series .

Below some examples scanned using Full Field and all at once in one session. By changing its angles, pause and resume scanning using turntable and also free handheld scanning .

LASER SCANNING MODES

14 Cross Laser mode use 14 laser lines crossed to capture individual points when you moving the laser back and forth on the scanned surface , Cross mode is different from Full Field as it only capture individual points and not full frame as once as Full Field, so it is more time consuming process , Cross mode also require markers as tracking points, it produce less overlapping if any and almost completely reduces ghosting or as we call it mandalas effect when the object drift away . It is more stable and great to scan featureless objects , it preserves well the cavities and picks .

7 lines Parallel mode is a laser scanning technology same as Cross mode, but only use 7 laser lines for scanning , it is great for scanning smaller objects with less features as well or more detailed . It preserve all the cavities and picks on your scanned object . As Cross mode it is most time consuming because it has only 7 lines so you have to spend more time moving it across your object to capture all the points .

[PUTV]

Auto scanning mode uses Dual Axis Turntable that is included with your MetroX package , it allows you to scan very fine models with very fine superior details automatic . It activate also RGB color mode where you can capture color per vertex or textures .

Lovely work there.

[ivan]

Just look at these scans!

For example, the small gnome figurine (70mm tall) → open the image in new tab and zoom in. Despite the small object size one can CLEARLY see each 3d layer, as it was obviously resin 3d printed. On other scans the same… Insane quality and details… wondering if laser mode is even needed

[misterpepper]

It’s possible those “layer lines” are artifacts from the scan and not actually in the part itself. For example, you can see similar lines in both of the scans of the scanned MetroX units. That said, they are clearly visible in the dental scan but not the large coin/coaster artifact below, and both are similarly sized so, assuming the same scan settings were used, you would expect similar artifacting. Regardless, the captured detail looks great and perfectly useable for what I am wanting the MetroX for.

[ivan]

I know what you mean. But if those were artefacts, I would expect them be either on some areas and/or in different /irregular directions .
@PUTV : can you please maybe share photos of these objects and let us know if my assumption about them being details rather than artefacts is right or wrong?

[PUTV]

@misterpepper

It’s possible those “layer lines” are artifacts from the scan and not actually in the part itself. For example, you can see similar lines in both of the scans of the scanned MetroX units.

The lines are the micro rows of the rubber parts so your fingers don’t slide while holding it .
They are bearly even visible .
The other Gnomes and figurines are made from wood .

It is possible to get sometimes artifacts when scanning at a specific angle and that is totally normal , 3D scans are not CAD models , expecting it to be perfectly smooth is unrealistic expectation .
On top Full field is so powerful it can capture small dust particles or hair and finger prints .
I hope you enjoyed so far the Showcase .

[PUTV]

Hi Ivan , thank you for the kind words .
Yes you can feel the lines because it is part of the rubber details to better grip it to prevent sliding .

[Linwood]

Very impressive scans!

A question about the Full Field:

Did you use scan spray or markers for any of those scans?

[PUTV]

@Linwood

Did you use scan spray or markers for any of those scans?

You need to use 3D spray for objects that have very contrasting colors as contrast color will react differently to each other .
The puppy dogs were scanned without 3D spray and are more detailed because MetroX full field can pickup everything and 3D spray can cover some details .
The Car Hub Cap was without spray , the small gnomes was with 3D spray the Coin without , the others partial .
The Hand was without . The teeth cast without
When you scanning objects where one part is bright and the other darker , you first set the exposure on low and scan the lighter area first , then pause and change the exposure to higher and scan another pass to capture the darker parts .

I mostly hand hell the MetroX in my hand for all the scans , I only use tripod or Desk Arm for single shot modes like scanning the MetroX itself , I prefer single shot modes that be stabilized and not shaking , I finish the scanning with 192 single frames .

I did not used markets for Full Field not even for scanning MetroX and I was surprised by that . For scanning the coin I added small cubes around for stabilization .

I collected the scans in the last 17 days .

Full Field is my favorite mode , quick , precise, crazy fine details and scanning in no time .

[Linwood]

Thank you for the detailed response.

That’s a great tip too, to adjust the exposure mid scan to get all the contrasting parts!

Were the Mini and MetroX scans using spray?

I got excited seeing the MetroX’s laser modes which made me back it quickly but as I read and see more and more I feel like the Full field mode is going to be my preferred choice.

Some of my best scans were with the original Mini but unfortunately the FOV is so low. Seeing just how big the FOV is on the Metro really makes it really exciting.

[PUTV]

@Linwood

Were the Mini and MetroX scans using spray?

Just partially on the lenses on MetroX.

And you welcome … for me Full Field mode is the reason I switched to Revopoint scanners for my work , quick and efficient.
With the Laser I feel like back to iron clothes in place of steaming it not for me , I have no the arm for that either.

There are situations where you need to use Laser but for me I can’t place markers over my stuff as it takes away the surface details so personally for my work I prefer Full Field 64 lines .

And compared to MINI series it is completely on another level , strong and bright … and easy to capture any color surface .

And of course bigger FOV
I am 99% sure that at the end everyone will enjoy Full Field over everything . If MetroX only have full field I would still back it on KS just for that .
Mini series was great but sadly retired for me already …

Anyway you gonna have 4 scanners in one … always a choice to switch modes for a specific task , you can’t go wrong with that .

[ivan]

@PUTV

If MetroX only have full field I would still back it on KS just for that .

This!

[PUTV]

@ivan

This

Of course Ivan , for what many of us need it , this is the way !

Additional modes always welcome , but my first love will be always Full Field 62 Lines until anything better arrives in the future .

Now I am thinking , imagine Blue Full Field with the FOV of Range ! Perfectly smooth surfaces ! Hmmm

[WilIam]

I can’t believe how amazing the scans looks like considering we paid so little for the package.
I don’t comments often but I would like to see more scans using Laser mode , my interest are objects that have less details, straight lines and cornes .

Thank you for the great showcase! so far so good and looking forward to see more, really appreciate it .

[PUTV]

Hi @WilIam

Thank you for your lovely comments.
Yes I will post more scans in the coming days after the weekend , also working on videos .

Stay tuned !

@PUTV

imagine Blue Full Field with the FOV of Range

guess what…
