Ancient gilded frame - 19th century - POP 2 scanning with Aesub spray

Hi everyone,
today post the test of an object particularly difficult to scan (reflective surface, decoration with repetitive motif).

The surface was prepared with the specific Aesub 3D scanning spray. It is a product that dulls and whitens the surface. After application, the material sublimates and fades leaving the original surface unaltered (here after 24 hours - only on the gilded frame are some residue, on the painting is vanished completely).

The complete sublimation of the product takes place according to the ambient temperature (on hot days the sublimation accelerates, on cold days it slows down).

I scanned using the hand held POP 2 scanner.
I used the high accuracy mode. The scans were 8 in total (in the final alignment in Meshlab I used 7).

In Meshlab I carried out the editing of the scans (saved as a point cloud) and the subsequent alignment.

Finally I proceeded to create the mesh (doing some tests to find the best surface rendering).

The result is very interesting, you have to work a little on it (but this is generally necessary for the use of any type of scanner).


I’m impressed with your results.

I wouldn’t mind a small tutorial on the use of MeshLab as it pertains to the work you did here, if you can spare the time. It wouldn’t have to be particularly detailed, but a list of the functions you used and how you determined the parameters for each function would be very useful.


Hi Jeff Lindstrom
with the new year I am committed (I hope) to make a (basic) tutorial of Meshlab to use it with scans made with POP 1-POP 2
greetings and best wishes for a merry christmas to you (and everyone)


Merry Christmas! Thanks for sharing!.

Your results are fantastic ! I also would like to see your workflow on it as the test #3 is fenomenal ! did you used the color data for the extra details ? or just pure cloud scan based ?

Hi PopUpTheVolume
Thanks for your appreciation!
I used the high precision mode, without the color.
Regarding the workflow, I refer you to another post of mine in which I explained step by step my way of working (POP 2 - 3D scanning of a dark and shining bronze - a nymph).
For scanning the gilded frame I used the previous version of the HandyScan software (beta 3). Beta 4 (for POP 1 and POP 2) has recently been released ([Windows] Handy Scan V4.0.0 - Beta version) with significant changes and improvements. With this version of the software it is possible to modify the settings concerning the resolution of the mesh, denoising and more. These last new settings allow you to operate directly in the software making editing with Meshlab unnecessary. Soon I will post my tests of the beta 4 (windows version) of HandyScan.


Thanks , definitely going to check it out ! looking forward to see the new test .
