MINI Revopoint - study of the surface traces on wooden sculpture (18th century) with Macro 3D Scanning

Hello everyone,
One of the important operations required in the preliminary study for the restoration of cultural relics is the study of the techniques of realization.
The Art Conservator carefully examines the cutural relic and records its observations to identify the constituent materials, construction techniques and tools used by the artist. In the latter case, the traces left on the surface of a wooden sculpture are the object of particularly in-depth study.
Precisely to study these traces, I use a technique that can be defined as “Macro 3D Scanning”: I scan portions of the surface of a cultural relics at high resolution and process the meshes with 3D software to enhance the traces present on the surface.
Below I post a series of these traces that I recorded on a wooden sculpture of the eighteenth century.

The scans were made with Mini Revopoint using the Feature, High Accuracy mode. After fusing, the Point Clouds were meshed at maximum resolution. The meshes were edited with Meshlab using the “Radiance scaling” shader and angling the “virtual” light in order to enhance the surface morphology. The snapshots were juxtaposed to photos of the corresponding areas.

Great examples and study Davide , excellent as always !
Always a pleasure to check out your work . Looking forward to see more great examples !

Wow nice work. I wish I had waited for the mini it looks like the mutts nuts

Remember MINI is not a replacement or upgrade to POP2 . It is just an additional tool , it can’t do what POP2 can and vice versa

I share the thought of PopUpTheVolume
Absolutely correct!
It serves to do other things than POP2 and POP1
The Revopoint team added another tool to the set

I appreciate they are different it’s just that I only want to scan small items anyway.

Interesting study.
Can you share with us the main dimensions of the wooden object ?
Have you performed a full scan of the object or just sample from areas of interest ?

Hi Laurent
The sculpture is this

The idea is similar to the macro photography
a portion of the surface scanned to the high resolution. Then elaborate with meshlab shader to study the fine traces surface morphology

What filter are you using in Meshlab. I’m always wanting to add new tools to my work flow. Great scans.

Hi Eric,
thanks for appreciation

You’re welcome. Thanks for sharing the filter. Now that I see it, i remember using it awhile ago. It is a really good filter for seeing more detail.

I wish we have different shading options in Revo Scan , the base one washing off the details what is good for textured objects , but to see the fine details of the actual scan is not .
The shader ( no filter) that Davide is using highlighting the edges of the scanned object the way it really is , not adding anything , it just trace better the edges bringing out the actual details to light .

Sorry for the mistake!
In the post I wrote correctly “shader” and in the reply to Laurent question, instead, I wrote “filter”
