in order to produce a digital reintegration that showed the appearance of the original paintings. Projection mapping was put into practice by projecting the digitally restored paintings onto the walls of the church’s apse, thus returning it to its full splendour as in 1123. An animation was also designed by Burzon*Comenge in collabora- tion with Playmodes to provide an audiovisual show that displayed in detail the compositional elements of this gem of Catalan Romanesque architecture which was granted World Heritage status by UNESCO in 2000 [online resource - video].257Pórtico de la luz - Cathedral of Santa María (Vitoria-Gasteiz)Fundación Catedral Santa María258 implemented a complex plan to fully restore the cathedral of Santa María de Vitoria (Álava), which has so far undergone various types of work using state- of-the-art technology with a view to opening it permanently.There are several proposals for disseminating this heritage. One is the use of projection map- ping to trace the evolution of the polychrome over time, from the sixteenth to the twentieth centuries, based on the studies conducted during the restoration process which have brought to light the original colour of the materials that had faded over time.This dissemination tool, called “El pórtico de la luz” (Portico of light), is a 3D projection system installed in the chapel of Paternina, which is located at the front of the atrium and namedafter the abbot who had it built. It creates an environment where visitors can visualise the evolution of the chapel’s decoration and the fresco paintings that were once there, while an o -commentary explains the details.In this case projection mapping has made it possible to use digital projection techniques to recover the historic polychrome decoration that is no longer extant [online resource - video].259Digital restoration of CaesarionSome of the most signi cant technological tools for disseminating heritage assets were used during the international exhibition on the culture of Imperial Rome, Keys To Rome,260 which took place simultaneously in Rome, Sarajevo, Amsterdam and Alexandria during 2014. Oneof them was Revealing Flashlight, which was developed at the LaBRI - Laboratoire Bordelais de Recherche en Informatique261 of Bordeaux University (France) and used projection mapping technology applied to damaged sculptures and reliefs that could not be fully appreciated (Ridel et al., 2014).262 For example, a bust of Ptolemy XV, known as “Caesarion”, with badly blurred fea- tures was used at the exhibition in the Library of Alexandria (Egypt). By means of 3D projections, visitors could view a digital restoration of the bust with the missing fragments reincorporated. At the exhibition at the Allard Pierson Museum in Amsterdam, video mapping was used for a relief onto which the original polychrome deco- ration was projected, thereby restoring elements that were lost but known from academic studies [online resource - video].263AC/E DIGITAL CULTURE ANNUAL REPORT 2017177The use of digital technologies in the conservation, analysis and dissemination of cultural heritage
