- The Swedish Pompeii Project started in 2000 as a research and fieldwork activity initiated by the Swedish Institute in Rome. The aim was to record and analyze an entire Pompeian city-block, Insula V 1. Since autumn 2011 a new branch of advanced digital archaeology, involving 3D reconstructions and documentation methods, was added to the project agenda. The insula was completely digitized using laser scanner technology and the raw data were employed to develop different research activities in the area of digital visualization. This paper presents the recent results of the 3D interpretation of the house of Caecilius Iucundus. This research activity was developed employing a large variety of historical and archaeological sources such as: archaeological reports, historical image documentation (printed as well as in edited material) and analysis of the in situ structures. This work was characterized by the experimentation of a new workflow of data development, where the elaboration of the interpreted structures took place directly in virtual space, using the scanned model as geometrical reference. This method easily connected all the historical and archaeological sources collected for the interpretation, opening a new discussion about different possible interpretation of the house. Moreover, a Cave Automatic Virtual Environment (CAVE) was used in different occasions as platform where the different hypotheses could be discussed in the context given by the actual state of the archaeological structures. The use of an accurate and resolute replica of the site as a backdrop for the virtual reconstruction allowed a high level of control on the proposed hypotheses during the interpretation process. This study enabled the acquisition of new and important information about the house, thus, bringing a significant contribution to the archaeological analysis of Insula V 1, suggested as pilot project for wider use.

- The Las Cuevas site is a Maya administrative and ceremonial center active during the latter part of the Late Classic period (700-900 AD) in Western Belize. It is of particular interest because a large cave resides directly beneath the largest temple in the site core. This paper presents the use of phase shift variation laser scanning technology (Faro Focus 3D) for the acquisition of the cave’s network of galleries (9 chambers) and a large excavation area (8x5 m) investigated in the entrance chamber in the summer of 2012. More than 300 scans were made to acquire the entire cave and the amount of 3D data collected was more than 400 GB. The creation of different level of details allowed the alignment and triangulation of the 3D models of the different chambers and units. The dimension (24x20x10 cm; 5 kg) and accuracy (± 2 mm at 10-25 m) of the laser scanner allowed complete documentation of the cave and units in just three weeks of work. The importance of this work relies on the possibility to use the processed data to systematically improve the archaeological understanding of Las Cuevas’ complex cave system, favoring the interpretation of socio-cultural dynamics linked to cave environments during the Late Classic. The use of 3D technologies can, in fact, help the understanding of how the space in the cave was used in the past for rituals and ceremonies. Moreover, the 3D millimetric reproduction of the excavation process linked to the 3D survey of the entire cave will be instrumental for the archaeological record’s preservation. Future scholars will have the opportunity to retrace the work made by archaeologists at Las Cuevas, starting new discussion and interpretations of the same 3D archaeological context.
