Virtualizing the Temple of Bayon

Abstract

The Bayon temple—located at the centre of Angkor Thom and built by king Jayavarman VII (1181–c.1220)—has been virtualized several times since the ‘rediscovery’ of the Angkor site by Europeans in the middle of the nineteenth century CE. Some of this ‘virtualization’ has involved artistic interpretations of the Bayon, while others were actual archaeological reconstructions based on knowledge of the monument at that time. The layout of the Bayon is its first virtualization, and its evolution from the end of the nineteenth century to the 1960s, shows the complexity and the difficulty met by the explorers and architects who have tried to depict the temple. This paper discusses the recent virtualization of this complex Khmer temple as a three-dimensional model based on a specific context of the building’s archaeological history. Like classical archaeological reconstruction drawings, the main purpose of this kind of virtualization of ancient buildings using 3D modelling is the depiction of a monument in its original shape before deterioration. In the specific case of the Bayon, this purpose poses several challenges linked with the site’s complex architectural history. It is not just one archaeological reconstruction but rather a series of reconstructions that are needed in order to depict the different chronological incarnations of this temple.
