Seller Spotlight: RMN-GP Photo Agency
8 May 2018
The Photo Agency of the Réunion des Musées Nationaux – Grand Palais (RMN-GP) is the first
institutional partner to join the Sketchfab Store – commercially licensing 3D scans of real artifacts
from world renowned French museums.
An introduction to Réunion des Musées Nationaux – Grand Palais
Since 1946, the RMN-GP Photo Agency – a public institution under the authority of the French
Ministry of Culture – has been officially responsible for promoting the collections of France’s nationalmuseums. For more than 60 years, the agency has carried out photography, each year capturing
more than 20,000 new on-site images expanding the agency’s extensive media library, universallyavailable at photo.rmn.fr.
Our website provides comprehensive access to entire collections. Over one million photographs ofartworks from France’s national and regional museums are accessible online, including images ofcollections from the Louvre, the Musée d’Orsay, the Centre Pompidou, Chantilly’s Condé Museumand Palais de Beaux Arts of Lille.
The agency also has an international distribution network of exclusive agents in many foreigncountries. Prestigious foreign collections, including London’s National Gallery, New York’s
Metropolitan Museum of Art, Dresden’s Gemäldegalerie Alte Meister and Florence’s Uffizi Gallery, arealso available.
From Leonardo da Vinci’s Mona Lisa to Monet’s Water Lilies, from Titian to Fernand Léger, fromOceania’s masks to Asian art, and including paintings, sculptures and drawings, the website allowsvisitors to tour the greatest collection of images of art.
How did RMN-GP Photo Agency begin working with 3D?
The agency began 3D scanning in 2013 and has produced models with more than 12 nationalmuseums including Le Louvre, Orsay Museum, Sèvres Limoges, the Picasso Museum, the Guimet
Museum of Asian Art and more.
All the models the Agency produces are made available to institutions to enable their mediation andpromotional activities.
How is Sketchfab used at RMN-Grand Palais?
All RMN3D models are available on Sketchfab and in turn are embedded back into the website of thePhotographic Agency of the RMN-Grand Palais.
The Sketchfab platform allows us to host and publish 3D files online and the 3D player allows thedisplay of models on all browsers and on any screen – from smartphones and tablets to virtual reality
headsets.
Publishing on Sketchfab allows easy integration of the models on the museum websites, as well as
on social networks without having to install a particular plug-in.
The museums can thus display 3D models of the works in their collections directly on their own
websites, but also on the social networks or on scholarly websites, such as Panorama de l’Art.
Why did you decide to offer 3D models via the Sketchfab Store? How easy was it to use theStore (i.e. upload models, set a price, share)
The Sketchfab platform is perfectly adapted to our needs; we can put high quality, high resolution
models online, which is very important for the scientific community of museums. Many othermuseums around the world have also chosen to share on Sketchfab and it has been obvious to us tooffer a selection of models for direct purchase on the website. Selling from the website is very simple
and we can easily adapt and modify the price or the selection of models available for sale.

Why is it important to allow for commercial re-use of cultural heritage 3D content?
How do you hope the 3D data will be re-used?
The presence of models from French national museums is very important because their display
allows the promotion of these works of art. Their commercial use maybe in movies, video games oron the web and social networks contributes to knowledge and artistic education.
We acknowledge that the opportunities for re-use of 3D scanned cultural heritage models is in its
early stages and are please to be leading the way.
How and why does RMN-GP currently use 3D content online and within exhibitions (e.g. Siteséternels,Gauguin l’alchimiste)?
In 2016, the agency made 3 models that were integrated into the scenography of the exhibition“Eternal sites” at the Grand Palais. Three emblematic works lent by the Louvre Museum weremodeled and presented in the introduction of each sequence of the film “universal space”, thus linking
immersive videos and real works presented to the public.
The “Gauguin l’alchimiste” exhibition at the Grand Palais in 2017 was also an opportunity to highlightthe agency’s 3D models: more than 30 works by Paul Gauguin have been digitized inphotogrammetry with a very high precision guaranteeing their geometric and colorimetric conformity:
twenty-one carved and ceramic sculptures and eleven paintings, lent by the Musée d’Orsay, havebeen modeled. These 3D models have been included with the film’s broadcast along the exhibitionand extend the catalog and other publications of the RMN-Grand Palais with augmented reality.
How do you see 3D changing the way museums and cultural organisations work in the future?
3D models are becoming increasingly important for sharing, dissemination and exhibition use. 3Dmodels are particularly suitable for use on interactive displays in museums, where museum patrons
can view all sides of the work and zoom in or out to view all the details. In the future, augmented
reality will enhance book editions, postcards and other print media.
Another direct application concerns education, given the current capabilities of smartphones andtablets, the potential impact of augmented reality could be very important in the short term.
Preparing 3D data for re-use
Describe a typical workflow for how you create or capture 3D?
[Présentation vidéo des processus de numérisation 3D par RMN-GP :https://www.youtube.com/watch?v=QrGPxDT1has]
What tools or equipment do you use?
Two modes of acquisition are now used by the agency, these are:-Scanning by 3D scanner, mainly used Artec Eva and Artec Spider which use structured light,
projecting the light in the form of parallel beamsScanning in photogrammetry using 24 x 36 camera positions.

The postproduction is different and does not use the same software, in the case of hand-heldscanners the agency uses Artec Studio to achieve alignments and merging parts of the model. In
photogrammetry, the software used is Capturing Reality (alignments and reconstruction).
The other software used, common to both methods of capture are:-Geomagic Wrap (cleaning, refilling and rebuilding)
ZBrush (Polygon cleaning and decimation)
Photoshop and Mari (color corrections and layer creation)
XNormal and 3DS Max

RMN-GP 2021 annual report (pages 218-219) confirming it holds nearly 2,000 3D scans:
https://www.grandpalais.fr/Rapports_Activite/2021/#/page/219
Pertinent text :« SOLID EXPERTISE IN SHOOTING 3D
The agency continues to lead the project France collections 3D, initiated in 2015 as partof a call for projects from the Fund for the Digital Society [Fonds pour la Société
Numérique] and has accumulated nearly 2,000 models in high definition. The
digitizations are carried out thanks to two technologies: with structured light scanners orbased on a photogrammetry process developed by the agency. During 2021, theagency carried out 25 days of 3D capture. Scans made include the Venus de Milo, theSleeping Hermaphrodite, the Lion of Monzón for the town hall of Monzón de Campos in
Spain, the cross section of the Opera Garnier for a multimedia application developed by
the Musée d'Orsay, as well as many works related to Napoleon I, in the dynamics of thebicentenary of his death (Austerlitz sword, bicorne hat, busts…). »(The photo show the Venus de Milo bring 3D scanned by photogrammetry)
