The following topics are dealt with: 3D reconstruction; human factors; virtual environments; media arts; digital performance; cultural heritage; museum environments; document analysis; augmented reality and serious gaming.
We review the recent application of computer graphics to problems in the history and interpretation of master artworks. Carefully constructed computer graphics models of tableaus in paintings allow scholars to explore "what if" scenarios concerning lighting, geometry, placement of subjects, physical properties (such as color and reflectance characteristics), and more. A special application...
We reconstructed a three-dimensional tableau from a single realist painting-Scott Fraser's Three way vanitas (2006)-based on multiple stereo reconstruction applied to the direct image and the images in three plane mirrors depicted within the painting. The tableau contains a carefully chosen complex arrangement of objects including a moth, egg cup, and strand of string, glass of water, bone, and hand...
Virtual restoration of Cultural Heritage (CH) artefacts is an important task that aims to re-create the original appearance of damaged items. In this paper we describe a method that can be used for virtual restoration of faces appearing in cultural heritage artefacts. Given a damaged face appearing in a 2D image we estimate the complete 3D shape of a face using data from the non-damaged face and we...
This paper describes the methodology adopted and the results obtained during the 3D documentation of the medieval capitals of St. Orso Collegiate Church, in Aosta, for reference and digital archiving. This task has been carried out through low cost technology entirely based on digital scanning of high quality images applying stereophotogrammetric principles. This technology allows to obtain point...
This paper describes the 3D digital documentation of a highly significant cultural heritage object from the Melanesian Southwest Pacific, held in the ethnographic collections of the British Museum. The object, which dates from about 1910, is a large plank-built war canoe from the island of Vella Lavella in New Georgia, Solomon Islands. 3D laser scanning is paired with anthropological research, which...
The stone of the elephant is a well known monument in the northern part of Sardinia, one of the main island in the Mediterranean sea. It is a large volcanic stone with a particular shape which recall the shape of an elephant. The natural forces worked on it giving to the stone a strange elephant shape; the ancient humans worked on it carving sepulchers for their deaths; in the contemporary age, after...
As can be deduced from the work carried out in different projects, the objective of our 3D modelling laboratory is to examine the capacity of 3D laser scanner systems to model archaeological artefacts and compare the results to those obtained by photogrammetry, and to optimise registration by combining and innovating in both technologies. Another archaeological area which we have begun to investigate...
In this paper we present a methodology to accurately derive 3D photo models of a World Heritage monument by means of terrestrial laser scanning (TLS) and close range photogrammetry. TLS will provide 3D point clouds as well as rough photo models that can substantially be improved draping texture with external imagery. The tomb Djin Block No. 9 in Petra is used to compare texture results delivered by...
The ability to predict whether people will experience anxiety is important for recruitment and selection in highly-stressful professions. Using a virtual reality environment (VRE) can provide a tool to predict whether a person will experience anxiety. This paper reports several regression models which suggest observed and self-reported measures of anxiety during and after immersion in a VRE can be...
3D virtual environments (VE) are real; they exist as digital worlds with the advantage of having none of the constraints of the real world. As such they are the perfect training ground for design students who can create, build and experiment with design solutions without the constraint of real world projects. This paper reports on an educational setting used to explore a model for using VE such as...
In this paper we describe part of the MediaEvo project on a Digital Heritage application aimed to serve as an edutainment tool. Visitors are able to virtually explore the reconstructed heritage environment of Otranto town and learn about the medieval world through a virtual experience. The project aims to identify the methodologies related to interactive learning and an approach oriented to the instructive...
The Lorsch Abbey World Heritage Site is a good example for a detailed London Charter implementation guideline. The information system attempted here strives for a combination of architectural 3D-models based on physical remains with historical and recent source materials. It needs to be suited for sites with heterogeneous and sparse sources, which heavily rely on the interpretation and the possible...
We present a multi-contextual interactive project which aims to create an open and real-time musical environment extending a natural ambient environment, namely an urban landscape. The basic idea is to convert in real-time the input from a camera sensor recording a urban landscape (in our first test-case: Tokyo city at night) into an electronic musical soundscape. This is achieved by considering each...
