Exhibition of the 3D scan film: ‘Virtual Reconstruction’ in the Chilean selection ‘Dramatic varieties: Chilean Architecture in Action’ at the Architecture Film Festival UK. Bargehouse, OXO Tower. London, UK. 7th-11th June 2017. More information: http://dramatic-varieties.com/films/
The use of new technologies to record existing architectures is increasing as they become affordable and more accessible than ever before. Among them, 3D laser scanning is of particular relevance since it can provide full documentation of the reality in the form of a measurable coloured three-dimensional point cloud, from which different outcomes can be generated. The films explore the potential of the 3D laser scanner technology as a documenting tool and its importance to record built heritage that is at risk of disappearance due to natural disasters.
The work compiles films rendered from a 3D laser scanning record done in Chile in January 2013 in the heritage villages of San Lorenzo de Tarapacá and Zúñiga (displayed). The first case was affected by the 2005 earthquake and the following case by the 2010 earthquake. In 2013, these three settlements represented different status in their reconstruction process. While San Lorenzo de Tarapacá was already reconstructed —although several buildings were stills in ruins—, Zúñiga was in almost the same condition after the 2010 earthquake.
The 3D laser scanning was done during only three days in each village and was part of the fieldwork for Bernadette’s current PhD research titled: ‘Re-construction and record: exploring alternatives for heritage areas after earthquakes in Chile’, supervised by Professor Stephen Gage and Professor Dr Camillo Boano at The Bartlett School of Architecture & DPU, University College London.
From the aerial navigation of the heritage area of San Lorenzo de Tarapacá to the smallest scale of a house in Zúñiga, the films explore the quality and possibilities that the digital 3D scan model offers, where we can even have a glimpse of the dwelling conditions.
Special thanks to Diego Ramírez, Max Cruz, Fernanda Vargas and Francisca Carter for their help in the on-site data capture and to Diego Ramírez to facilitate the 3D scanner equipment in Chile.
