Abstract
Studying works that have completely or partially disappeared is always difficult due to the lack of information. In more fortunate scenarios where photographs were taken before the destruction, the study of the piece is limited by the viewpoints captured in the available photographs. In this interdisciplinary research, we present a new methodology for reconstructing lost altarpieces from a single historical image, utilizing differentiable rendering techniques. We test our methodology by reconstructing some reliefs from the altarpiece of Sant Joan Baptista (Valls, Spain), which was destroyed in 1936. These results are valuable for both experts and the public, as they facilitate a better understanding of the relief's volumetrics and their spatial relationships, representing a significant advancement in the virtual recovery of lost artifacts.
