The paper focuses on the challenges of creating a computer visualization of a site with scarce source
data, originally gathered for documentation purposes only. The particular site considered in this article
is a Roman maritime villa in the bay of Stari Trogir, Central Dalmatia, Croatia. The well-preserved
remains are constantly under threat of destruction, as they are exposed to local construction work.
First described in the 17th century, and sporadically researched from the early 20th century, the remains
were again newly documented and interpreted in 2004. They are especially interesting because of their
peculiar semi-circular structure. The objective in the present work is to create virtual presentations of
multiple interpretations of the site, to tell a story about the locals’ home. This should encourage an
emotional connection with the remains and induce respect towards the place’s history, as well as the
desire to preserve and protect it.

While traditionally archaeological research has mainly been focused on individual cultural heritage monuments or distinct archaeological sites, the Austrian based Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology goes beyond the limitations of discrete sites in order to understand their archaeological context. This is achieved by investigating the space in-between the sites, studying entire archaeological landscapes from the level of individual postholes to the mapping of numerous square kilometres. This large-scale, high-resolution, multi-method prospection approach leads to enormous digital datasets counting many terabytes of data that until recently were technically not manageable. Novel programs and methods of data management had to be developed for data acquisition, processing and archaeological interpretation, in order to permit the extraction of the desired information from the very big amount of data. The analysis of the generated datasets is conducted with the help of semi-automatic algorithms within complex three-, or even four-dimensional geographical information systems. The outcome of landscape archaeological prospection surveys is visually communicated to the scientific community as well as to the general public and stakeholders. In many cases, a visualization of the scientific result and archaeological interpretations can be a powerful and suitable tool to illustrate and communicate even complex contexts to a wide audience. This paper briefly presents the great potential offered by a combination of large-scale non-invasive archaeological prospection methods and standardized workflows for the integration of big data, its interpretation and visualization. The proposed approach provides a context for buried archaeology across entire archaeological landscapes, changing our understanding of known monuments. We address the overcome and remaining challenges with the help of examples taken from outstanding landscape archaeological prospection case studies. Resumen: Aunque tradicionalmente la investigación arqueológica ha estado fundamentalmente centrada en monumentos y yacimientos arqueológicos de forma individual, el Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology (Austria) va más allá de los límites de yacimientos particulares con el objetivo de entender su contexto arqueológico. Esto es conseguido mediante la investigación del espacio entre yacimientos y estudiando paisajes arqueológicos completos yendo desde un hoyo de poste hasta el mapeado de varios kilómetros cuadrados. El enfoque de prospección multi-metodológico a gran escala y de alta resolución conduce hacia un enorme conjunto de datos digital que incluye varios Terabytes de información los cuales no habían podido ser manipulados hasta hace poco debido a limitaciones tecnológicas. Por consiguiente, nuevos programas y métodos de gestión de datos han sido diseñados para la adquisición y procesado de datos así como interpretación arqueológica para así permitir la extracción de la información deseada desde estos enormes bancos de datos. El análisis de estos conjuntos de datos generados es llevado a cabo a través de análisis de sistemas de información geográfica tridimensionales e incluso cuatridimensionales. El resultado de la prospección de paisajes arqueológicos es transferido de forma visual a la comunididad científica así como al gran público e interesados en la materia. En muchos casos una visualización de los resultados científicos e interpretaciones arqueológicas puede ser una herramienta más poderosa y adecuada para ilustrar y comunicar contextos arqueológicos complejos a un público mayor. Este artículo presenta de forma breve el gran potencial ofrecido por la combinación de métodos de prospección arqueológica de gran resolución a gran escala y unos flujos de trabajo estandarizados para integración, interpretación y visualización de datos.

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.

Diplomsko delo se osredotoča na virtualno dediščino in njeno uporabo v arheologiji. V teoretičnem delu je predstavljen princip računalniške vizualizacije. Na podlagi izhodiščnih podatkov, kot so najdbe in dedukcije, analogij in domnev se izoblikuje računalniški model, ki je lahko predstavljen na več načinov (fotorealistično, ne-fotorealistično, na način obogatene resničnosti) in v več oblikah (slika, animacija, virtualna resničnost).
Predstavljene so tehnike pridobivanja podatkov (fotogrametrija, ročne meritve, meritve s teodolitom, lasersko skeniranje) in nekaj komercialnih in odprtokodnih programov za obdelavo in vizualizacijo.
Takšni računalniški modeli so v primeru natančnosti uporabni v strokovnem kontekstu, kjer so v podporo raziskavam v smislu upravljanja izkopavanj ali dokazovanja teoretskih razprav. Drug vidik njihove uporabe je informiranje javnosti v muzejih, na najdiščih samih ali preko medijev.
Učinkovitost takšne uporabe računalniških modelov je predstavljena na primeru rimske vile v zalivu Stari Trogir v srednji Dalmaciji. Predstavljena je njena lega, stanje raziskav in ugotovitve iz terenskih pregledov v letu 2004. Sledi opis postopka vizualizacije sedanjega in nekdanjega stanja. Za generiranje modela nekdanjega stanja so prikazani argumenti interpretacije arhitekturnih ostankov kot rimske vile maritime in analogije posameznim interpretacijam prostorov vile. Vključeni so rezultati računalniške vizualizacije v podobi slik in animacij.

Ključne besede: računalniška vizualizacija, virtualna dediščina, vila maritima.

The degree paper focuses on virtual heritage and its application in archeology. In the theoretical part the principle of computer visualization is presented. On the basis of fundamental data, such as finds and deduction, analogies and assumptions a computer model that can be represented in several ways (photo-realistic, non-photo-realistic, augmented reality) and in several forms (image, animation, virtual reality) is created.
Data acquisition techniques (photogrammetry, manual measurements, theodolite measurements, laser scanning) and several commercial and open source software for processing and visualization are also presented.
Such computer models are useful in the case of precision in a professional context where they support research in terms of managing excavations or as a proof of theoretical discussions. Another aspect of their use is informing the public in museums, on sites, or through the media.
The effectiveness of such use of computer models is presented in the case of a roman villa in the bay of Stari Trogir in central Dalmatia. Its location, history of research and findings from field inspections in the year of 2004 are presented, followed by a description of the visualization of the current and former condition. To generate a model of the former state arguments are presented for interpretation of architectural remains as a maritime roman villa and analogies for interpretations of individual villa's rooms. The results of computer visualization in the form of realistic images and animations are included.

Key words: computer visualization, virtual heritage, maritime villa.
