Many altarpieces, which are very relevant Christian art elements, have been damaged and\/or partly or fully lost. Therefore, the only way to recover them is to carry out their digital reconstruction. Although the procedure that we present here is valid for any altarpiece with similar characteristics, and even for other akin elements, our test bench is the altarpieces that were damaged or destroyed or that disappeared during the Spanish Civil War (1936\u20131939) in Catalonia, where most suffered these effects. The first step of our work has been the classification of these artworks into different categories on the basis of their degree of destruction and of the available visual information related to each one.<\/jats:p>\n          <jats:p>This article proposes, for the first time to our knowledge, a workflow for the virtual reconstruction, through photogrammetry, digital modeling, and digital color restoration, of whole altarpieces partially preserved with very little visual information. Our case study is the Rosary\u2019s altarpiece of Sant Pere M\u00e0rtir de Manresa church. Currently, this altarpiece is partially preserved in fragments in the Museu Comarcal de Manresa (Spain). But it cannot be reassembled physically owing to the lack of space (actually the church does not exist anymore) and the cost of such an operation. Thus, there is no other solution than the digital one to contemplate and study the altarpiece as a whole. The reconstruction that we provide allows art historians and the general public to virtually see the altarpiece complete and assembled as it was until 1936. The results obtained also allow us to see in detail the reliefs and ornaments of the altarpiece with their digitally restored color.<\/jats:p>","DOI":"10.1145\/3652860","type":"journal-article","created":{"date-parts":[[2024,4,3]],"date-time":"2024-04-03T12:08:19Z","timestamp":1712146099000},"page":"1-18","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Digital reconstruction of partially lost altarpieces.
