Virtuuvius - Automated Drawing of Temple Architecture According to Vitruvius - the Case of the Temple of Hercules in Celje, Slovenia
(IEEE, 2015) Jerala, Maja; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The study of Roman temple architecture usually involves a multitude of ruins which need to be properly examined and, if possible, reconstructed. The reliability of a reconstruction - how closely it mimics the original situation - is determined by how well a temple is preserved. Fortunately, there is a transcription of a work on architecture written by one of the most notable Roman architects, Vitruvius (late 1st century BCE). Vitruvius' rules define the basic module and all the proportions to the tiniest detail, but also in a broader architectural sense. For proper analysis, interpretation and reconstruction of the temple of Hercules at Celje, Slovenia, it was therefore crucial to take precise measurements and to conduct an analysis of the preserved elements, applied to the Vitruvian canon. Vitruvius' rules and principles concerning individual properties have been transformed into formulas (Microsoft Office Excel 2013), which automatically adjust to each other, according to the basic module. On the basis of these findings, it has been possible to create a reconstruction of the basic elements using the AutoCAD Architecture 2014 software. To link the two methods, i.e. determining the dimensions and 3D drawing of stone blocks, an interface (AutoCAD VBA Macro) is being prepared: Virtuuvius - Virtual Vitruvius.
3DHOG for Geometric Similarity Measurement and Retrieval for Digital Cultural Heritage Archives
(IEEE, 2015) Eckeren, Katharina van; Tausch, Reimar; Santos, Pedro; Fellner, Dieter W.; Gabriele Guidi and Roberto Scopigno and Juan Barceló
With projects such as CultLab3D, 3D Digital preservation of cultural heritage will become more affordable and with this, the number of 3D-models representing scanned artefacts will dramatically increase. However, once mass digitization is possible, the subsequent bottleneck to overcome is the annotation of cultural heritage artefacts with provenance data. Current annotation tools are mostly based on textual input, eventually being able to link an artefact to documents, pictures, videos and only some tools already support 3D models. Therefore, we envisage the need to aid curators by allowing for fast, web-based, semi-automatic, 3D-centered annotation of artefacts with metadata. In this paper we give an overview of various technologies we are currently developing to address this issue. On one hand we want to store 3D models with similarity descriptors which are applicable independently of different 3D model quality levels of the same artefact. The goal is to retrieve and suggest to the curator metadata of already annotated similar artefacts for a new artefact to be annotated, so he can eventually reuse and adapt it to the current case. In addition we describe our web-based, 3D-centered annotation tool with meta- and object repositories supporting various databases and ontologies such as CIDOC-CRM.

Surface Shape Studies of the Art of Paul Gauguin
(IEEE, 2015) Cossairt, Oliver; Tumblin, Jack; Huang, Xiang; Stratis, Harriet; Broadway, Mary; Bearman, Greg; Doehne, Eric; Walton, Marc; Matsuda, Nathan; Katsaggelos, Aggelos; Kronkright, Dale; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Starting in the 1890s the artist Paul Gauguin (1848- 1903) created a series of prints and transfer drawings using techniques that are not entirely understood. To better understand the artist's production methods, photometric stereo was used to assess the surface shape of a number of these graphic works that are now in the collection of the Art Institute of Chicago. Photometric stereo uses multiple images of Gauguin's graphic works captured from a fixed camera position, lit from multiple specific angles to create an interactive composite image that reveals textural characteristics. These active images reveal details of sequential media application upon experimental printing matrices that help resolve longstanding art historical questions about the evolution of Gauguin's printing techniques. Our study promotes the use of photometric stereo to capitalize on the increasing popularity of Reflectance Transformation Imaging (RTI) among conservators in the world's leading museums.
Studying Shape Semantics of an Architectural Moulding Collection - Classifying Style Based on Shape Analysis Methods
(IEEE, 2015) Echavarria, Karina Rodriguez; Song, Ran; Gabriele Guidi and Roberto Scopigno and Juan Barceló
As technologies for 3D acquisition become widely available, it is expected that 3D content will become increasingly popular. Nevertheless, to provide access and enable the creative use of 3D content, it is necessary to address challenges such as the availability of open repositories dedicated to 3D content and the automatic enrichment of 3D content with suitable metadata so that content does not get lost. To address these challenges, this paper presents research on developing technologies to support the organisation and discoverability of 3D content in the Cultural Heritage (CH) domain. The main contributions of the paper include an ontology for documenting 3D representations of architectural mouldings decorated with ornament. In addition, a shape analysis method to improve the information that is automatically extracted from a 3D shape is proposed. This method is tested on part of a collection of Regency ornament mouldings found in domestic interiors. This content provides a rich dataset on which to explore issues common to many CH artefacts, such as design styles, patterns and motifs.
Analyzing the Evolution of Deterioration Patterns - A First Step of an Image-based Approach for Comparing Multitemporal Data Sets
(IEEE, 2015) Peteler, Friederike; Gattet, Eloi; Bromblet, Philippe; Guillon, Odile; Vallet, Jean-Marc; Luca, Livio De; Gabriele Guidi and Roberto Scopigno and Juan Barceló
When documenting and analyzing cultural heritage, the monument states can be described by multitemporal data sets, which however present a complication for the elaboration and examination process. This difficulty leads to the necessity to improve the analyze process in order to expand the documentation process and help experts to enrich and share information about the historical buildings. Therefore an approach of change measurement, which supports the chronical comprehension of a building by visualizing and quantifying the dimensional temporal effects was elaborated, where the analyze process of a multitemporal data set was based on the interpretation of depth map images. These maps were obtained by generating ortho images of an object that was created on purpose by setting up an experimentation to acquire a multitemporal data set. This approach is the first step of a wider ongoing research about change detection processes on multitemporal data sets.
Unraveling the Classic Proportions Through the Anthropometric Analysis of the Architectural Heritage The Case of the Pantheon
(IEEE, 2015) Roldan-Medina, Francisco Javier; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Previous results of this research allow to raise the Hypothesis that a simple metric law is sufficient to justify the different dimensions of the various parts composing ancient architectural constructions, from its general layout to every single detail. This Hypothesis is based on the observation that any modulation in historic buildings match with the sides and diagonals of human-sized square pattern, and its duodecimal divisions. However, it´s not possible to match exclusively to the side-square scale, because the Side-Diagonal Dual Scale is necessary, and is sufficient. The analysis of scientific surveys with digital precision led to find the serendipity beyond the current state of the art demonstrating the compliance with this law in architectural works of very different historical periods. This research deals with the study of the Pantheon through the survey of the Bern Digital Pantheon Project. It is highlighted that from the obtained results, in addition to the compliance of the Principle of Proportionality proposed, the Pantheon presents similar modular patterns to those detected in other examples. Knowledge of this common System of Proportions used in the past could represent a scientific breakthrough or new paradigm in the study and preservation of architectural heritage.
Mapping Identity with Geo-technology: Montelupo/Italy Versus Santa Leopoldina/Brazil
(IEEE, 2015) Andrade, Bruno Amaral de; Almeida, Renata Hermanny de; Gabriele Guidi and Roberto Scopigno and Juan Barceló
This article is inserted in the hybrid-theme ''Heritage and Representation'', in the field of new methods of iconographic representation of the territorial-landscape heritage, through digital models of cartographic construction. The problematic identified in representations of the territory is solved from an analytical hierarchy of observation, interpretation and comprehension of the relationship between biotic and anthropic dimensions, with consideration of the title role of the ecological aspect of the territory, and its relation to the construction of identity. The hypothesis guides the evaluation and experiment of a consolidated Italian approach and its adoption to the Brazilian context. The objects of empirical study are the cities of Montelupo/Toscany/Italy, and Santa Leopoldina/Espírito Santo/Brazil, as locus to elaborate a comparative method in the environmental heritage category. The aim of this article is revealing how the environmental aspect of the territory is relevant to the construction of identity, through mapping by GIS software.
Exploration of the Changing Structure of Cities: Challenges for Temporal City Models
(IEEE, 2015) Périnaud, Clémentine; Gesquière, Gilles; Gay, Georges; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The ALARIC project (Incremental Urban Change Research Project) is dedicated to the production of geo-historical information concerning two formerly industrial cities of the Lyon-Saint-Etienne region (19th and 20th century). The explo-ration of the incremental nature of urban change implies identifying when certain historical processes took place, such as the shift from one-off to systematic construction and changes in urban planning strategies. Specifically, the case stu-dy investigates the emergence of local urban projects to compare the transformation processes of the urban fabric and to specify the pace of urban change. Historical records will be accessed through a virtual mapping environment based on the temporal reconstitution of cities in two dimensions, and sometimes for special cases in three dimensions. This paper presents methodological principles to reconstruct former cities in order to inquire urban change and requirements for effective sharing of hypotheses on the various states of the past urban landscape and associated transformation processes.
Precise 3D Recording for Finite Element Analysis
(IEEE, 2015) Kalisperakis, Ilias; Stentoumis, Christos; Grammatikopoulos, Lazaros; Dasiou, Maria Eleni; Psycharis, Ioannis N.; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Lately, 3D laser scanning and Photogrammetry are becoming a standard in Cultural Heritage recording. In this contribution, a combination of both methods is presented for the precise 3D geometric documentation of a plaster copy of a Greek statue from the archeological site of Delos. The 3D model was generated for the structural assessment of the original statue and its supporting mechanism via finite element analysis (FEA).
Interdisciplinary Workflow for Virtual Archaeology
(IEEE, 2015) Luznik, Nika; Klein, Michael; Gabriele Guidi and Roberto Scopigno and Juan Barceló
There is an increasing trend to present cultural heritage with the help of virtual visualisation. It offers a unique level of understanding of the heritage in question. Moreover, depending on the precision of the virtual model, it can be used for scientific research, and it can inspire new ideas and conclusions about the actual looks of the visualised objects. Over the years, companies and institutions have specialized in this field of work, creating new demands on the CG artists of the involved teams, as well as establishing a new kind of archaeological methodology that seeks to research and develop ways of using computer-based visualisation for the comprehensive management of archaeological heritage. However, the interpretation of archaeological datasets and their subsequent transformation into 3D representations of the interpretation usually requires a timeconsuming process of re-evaluation and discussion. Very often, a discrepancy between scientific architectural interpretation that is normally presented in a 2D plane and its realisation in a 3D space occurs, because the 2D representation is not able to show the physical laws of the third dimension. To overcome these difficulties, we propose alternative solutions that lessen the disconnection between the parties. Our software solution enables the archaeologist to perform an interpretative work-flow that places ideas within a customizable 3D environment, therefore resulting in a more direct involvement throughout the reconstructive or representative process. On a broader scale, CGI artists would benefit greatly if they could follow the project evolving and gain a deeper understanding of the specific cultural heritage.

Building Information Modelling for Historical Building Historic Jeddah - Saudi Arabia
(IEEE, 2015) Baik, Ahmad; Boehm, Jan; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The topic of how the municipality of Jeddah can document, produce and preserve complete engineering information and drawings for historical buildings is one of the most important issues facing the Historic Jeddah district in the Kingdom of Saudi Arabia. The concept of using a remote collection of survey data with Architectural Photogrammetry and Terrestrial Laser Scanning has been accepted in several heritage locations worldwide. Additionally, the combination of the resulting information and Building Information Modelling has been developed as a technique to manage and document these historical buildings. In the last 20 years, several traditional approaches have been used to document, record, and survey heritage buildings in Historic Jeddah; however, these techniques have sometimes delivered unreliable information, taken a long time and inevitably omitted key details. This paper will focus on using Jeddah Historical Building Information Modelling; to produce complete engineering information and drawings.

(IEEE, 2015) Gabellieri, Nicola; Panetta, Alessandro; Pescini, Valentina; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Research in environmental archaeology and historical ecology provides valuable information about past vegetation and its activation related to past societies activities. Different tools are use in order to better describe the historical plant coverage and ecosystems, environmental resources and the agro-silvo-pastoral systems. Combining field data and historical information in a GIS application gives multiple perspectives on the dynamics of changing landscape. This paper deals with the issue of GIS as a tool for historical ecology research, outlining the used methodologies and problems related to them. Our study focuses on Punta Mesco, in the Cinque Terre National Park (Italy), as case study.

A Mono-instrumental Approach to High-quality 3D Reality-based Semantic Models. Application on the Palladio Library
(IEEE, 2015) Gaiani, Marco; Apollonio, Fabrizio I.; Clini, Paolo; Quattrini, Ramona; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The paper presents a new workflow to build geo-3D models able to populate a wide information system organizing and managing Palladio's works documentation. Main goal is to smooth the integration of data from different sources and promote a more profound understanding of Palladio's works. Starting from an integrated survey approach (laser scanner and Multi-Image Spherical Photogrammetry), reality-based 3D models are robustly constructed and semantically segmented from point cloud features based on Palladio treatise architectural semantics. The 3D models outputs are exported into a 3D Geographic Information System (GIS) to facilitate the visualization of Palladio's works with reference to topography. At the end, an evaluation mechanism is employed to control the quality of 3D models. The workflow could be easily generalized to other architects documentation systems both because Palladian case is a superset of most of other architect documentation dataset, allowing to focus and to solve all existing problems and because techniques and methods are general and appropriate for most part of historical architectures.
