The reconstruction of an Egyptian mummy in Latvia

Final facial reconstruction of the mummy

Sveiki mani draugi!

Or "hello my friends" in Latvian. Latvia is a country in the Baltic region of Northern Europe, one of the three Baltic states. It is bordered by Estonia, Lithuania, Russia, Belarus and by a maritime border to the west with Sweden. Latvia has 1,997,500 inhabitants and a territory of 64,589 km².

TV story in a Latvian channel
It was precisely from this country, specifically from Riga, the capital, that I received a message via Facebook Messenger few weeks ago. The initial contact was made by the expert in stereoscopic technologies Artūrs Šlosbergs. He told me of a project involving the facial reconstruction of a mummy belonging to the Art Museum Riga Bourse collection.

First presentation of the 3D application with real-time manipulation via Kinect and stereoscopic view (3D glasses).
The project had two great challenges. 1) The mummy did not have richly segmented tomography, but only with some x-ray and CT with a few cuts in the body. 2) The project was to be finished soon as possible (it's my friends, this does not happen only in Brazil, like I thought).

Steps of facial and body reconstruction, starting from skull modeling and then the body's adequacy initially configured in MakeHuman and subsequently imported into Blender

As I worked on something similar in Tothmea project (an Egyptian mummy), where we reconstructed her skull joining data from multiple materials (CT-Scan, X-ray and photogrammetry) we could rebuild considerable part of the structure needed to make the reconstruction. It is clear that the volume of the skull of the last mummy is an approximation, but this was done using accurate data.

Bone structure previously configured in software MakeHuman
But the challenge did not stop there. Modeling the skull was only the first part. They would need a full body character to be animated via Kinect. Who works with modeling and animation knows that a full-length setup for this to be articulated is not a trivial task. Fortunately I had with me the MakeHuman, a free software to create "human beings parametrically." And among the many interesting features, it is possible to select a predefined rig system for the type of animation you need, be it for a movie or even a game, as was our case.

Adaptation of the mesh created in MakeHuman to the skull and the face drawn with the technique Manchester + Lebedinskaya.
To adapt the character to the game room they put me in touch with the game developer Jānis Lācis, and he guided me to know what we would need to change, since the deadline was short.

I also met Mr. Dmitrijs Ščegoļevs owner of PARUS studio Ltd., the company that hired me for this work. I must say that everything was very peaceful, the staff of Latvia is very objective and worked almost without sleep to make the application was finished. Even though I was weakened by a terrible sinusitis, the time zone and an excess of commitments could more or less follow them and end the task when the time was almost expiring.

Priest (mummy) properly linked and already with their costumes, compatible with the historical period from observations of archaeologist Dr. Moacir Elias dos Santos (thanks!). GLSL within Blender.
In addition to being kind people, Latvians are good at press office. Quickly the news of the reconstructed mummy took the headlines of some news sites.

Finally, I can only say I am very happy and pleased to have participated in this project. Thank you very much PARUS Studio, and thank you also to Professor Dr. Moacir Elias Santos for providential help regarding the clothing of the mummy.

A big hug to everyone and see you soon!

Member of Arc-Team receives an honorary title in Brazil

Small press conference. Below left Councilman Fernando Brandão and right Councilman Fernando Assumption.

Dear friends,

It is with great joy that I share with you the honorary title I received from the City Council of Sinop-MT in Brazil. This is an honorific title known as "Comenda Colonizador Enio Pipino," (Commendatory) that is offered the personalities that stand out in various ways, in my case was in relation to computer graphics work exercised with Blender and free software.

 [Subtitled in English] Clipping of TV stories presented during the vote to show the to show the projection of computer graphics work around the world

On November 10, 2014, during the 38th Session of the City Council, the Legislative Decree No. 022/2014 Project was presented under prot. No 808/2014, authored by councilors Fernando Brandão and Dalton Martini, whose main body describes the following:

Decree Law copy signed by the councilors.

"The City Council of Sinop - State of Mato Grosso, in exercise of its statutory duties approved and the President promulgate the following Legislative Decree:

Art. 1. Is granted the Commendation Colonizador Enio Pipino the Lord Cicero André da Costa Moraes - in recognition of the Municipal Legislature for its outstanding performance in computer graphics, helping to project Sinop around the country including at the international level."

Note newspaper with the title "Nerd Commendatory" describing the vote and talking about a creation of a scientif center based on free software

The project was approved unanimously in single vote.

It is important to document that thanks to this commendation the Jamerson Mileski Journal reporter Capital proposed the creation of a science institute devoted to the use of free software, and Councilman Fernando Brandão answered and will lead to the plenary at an early date.

Blog post of Councilman Fernando Brandão about the honorary title and the future project to establish a scientific research center focused to free software
This is the second honorary title issued by the City Council in two years. First it was a Motion of Applause also offered me due to the projection that the computer graphics work achieved at national and international level.

We of Arc-Team are glad and honored to realize that the authorities and representatives of the population are becoming more interested in free technologies, which above all contemplate the society widely.

We leave here our thanks to City Council of Sinop!

A study day in honor of Prof. Franco Ugo Rollo

Next week, on November 26, will be held a study day in honor of Prof. Franco Ugo Rollo, the famous anthropologist at the University of Camerino who sadly left us this year.
I have been invited to participate in the event, which will take place in Ascoli Piceno and Monsampolo del Tronto, where the Professor analyzed the mummy which are now exposed in the Museum of the Crypt of the S. Mary Church.
During the first session in Ascoli (in the morning) Prof. Gino Fornaciari (University of Pisa) will give a presentation titled "Fra principi e mummie: le origini della paleopatologia moderna" (en: "Between princes and mummies: the origin of modern palaeopathology". Later, Marco Samadelli, of EURAC, will speak about "Life Traces. Alla ricerca della vita nel microcosmo: batteri psicrofili e psicrotolleranti nella mummia dei ghiacci" (en: "Life Traces. Searching the life into the microcosm: psychrophilic  and psicrotollerant bacteria in the ice mummy"). Before the lunch break I will talk about "Volti in byte: le tecnologie digitali per la ricostruzione dei volti del passato" (en "Faces in bytes: new digital technologies for the forensic facial reconstruction of historical figures").
The second session will take place in Monsampolo, with a guided tour in the Museum of the St. Mary's crypt.
The event is organized by the University of Camerino (Scuola di Bioscienze e Medicina Veterinaria; Scuola di Scienze e Tecnologie, Corso di Laurea in Tecnologie e diagnostica per la conservazione e il restauro) and the municipalities of Ascoli Piceno and Monsampolo del Tronto. 

IMHO the study day promises to be interesting and it is worth to attend for people living in the nearby. For more information I publish here the official poster:

Arc-Team: Conflict Archaeology of the First World War on the Carnic ridge and in the Sexten Dolomites

With the centenary years 2014–2018, a hitherto relatively unknown branch of archaeological research, the so-called conflict archaeology, is coming into the limelight. Since  excavation work is able to supply only very selective assertions on account of the enormous extent of the mountain front, the overriding objective of monument conservation in the years to come must focus on taking stock of all material remains from the WWI era.

As a result of the developments in satellite geodesy and 3D documentation, it is now possible to approach this task on a wide scale and comparatively economically. The data collected form the basis of targeted protection measures and provide for future reference numerous new methods of presentation which fulfil the requirements of nature and monument preservation as well as the growing interest of demographic groups.

The article is illustrating the latest research results of Arc-Team and is written in German Language by Rupert Gietl. 
It was published inside the volume:
Das Pustertal und der Krieg 1914–1918 (TAP-Forschungen, Bd. 2) by the 
Tyrol Archive for Photography (TAP)

A Georgian mission: food for thought

Working as professionals in archeology sometimes means to be involved in projects abroad. Between Monday 22 and Friday 26 September 2014 Arc-Team participate in organizing a mission in Georgia to document the skulls of Dmanisi (Homo georgicus), in order to perform the facial reconstructions for the open source exhibition "Facce. I molti volti della storia umana" (en: "Faces. The many aspects of human history").

Dmanisi's panorama

The work was possible thanks to the kindness of Prof. David Lordkipanidze (of the Georgian National Museum) and to the precious help in logistic organization of our colleague and friend Zviad Sherazadishvili.

The excavation site

During the mission, carried out with Nicola Carrara (of the Anthropological Museum of the University of Padua), I had the opportunity to take some pictures regarding traditional food in Georgia and "pay my debt" with Lucia Galasso (according to this post).
This is the material I collect:

1. An Adjarian Khachapuri (one of my favorite Georgian dishes), served in a restaurant in Tbilisi.

Adjarian Khachapuri

2. Some Khinkali, for a fast lunch in Dmanisi.


3. A shop selling Churchkhela in Tbiblisi (for a good dessert).


I hope this post will be useful for food culture specialists, helping to discover and appreciate the culinary traditions of Georgia.
Once again I have to thank my friend Zviad Sherazadishvili for the kindness and help in organizing the mission!

QGIS: exporting 3D data in threejs

Hi all,
I go on recording small videotutorial regarding the software in ArcheOS 5 (codename Theodoric), trying to collecting more material for the official documentation.
In order to avoid the creation of "wasted food" (videotutorial which are not connected with a real project risk to be useless because too theoretical and too few practical), I am collecting examples from our (Arc-Team) work.
This time I will show how to export 3D data from QGIS and visualize them in a browser thanks to the nice plugin "Qgis2threejs". I I had the necessity to do this kind of operation just to create some screenshot to complete this very simple illustration that gives a geological overview of the working area:

Of course this is not the only way to collect 3D views (I could do the same in GRASS with Nviz), but this workflow is very fast, for a small project.

Here is the videotutorial (I hope it will be useful):

As ususal, the video is uploaded also in our Digital Archaeological Documentation Project.
Have a nice day!
