Quaternions, although not well known, provide a fundamental and solid base to describe the orientation of an object or a vector. They are efficient and well suited to solve rotation and orientation problems in computer graphics and animation. This paper describes two new methods for splining quaternions so that they can be used within a keyframe animation(More)
This paper discusses the rationale for—and describes the methodology of—a new system of interactive storytelling being developed by the Ename Centre for Public Archaeology Heritage Presentation in Belgium. Based on 5 years' experience with multimedia heritage presentation systems, both on-site and in museum contexts, this approach to the presentation of(More)
This paper describes the background and methods for the production of CIDOC-CRM compliant data sets from diverse collections of source data. The construction of such data sets is based on data in column format, typically exported for databases, as well as free text, typically created through scanning and OCR processing or transcription.
Museums often lack the possibility to present archaeological or cultural heritage sites in a realistic and interesting way. Thus are proposing a new way to show augmented reality applications of cultural heritage sites at remote places like museums. In the exhibition space large wall-filling photographs of the real site are superimposed with interactive(More)
In recent years, 3D and virtual reality have emerged as areas of extreme interest as methods for visualizing digital museum artefacts in context, and particularly over the Internet. The technology associated with these new visualization techniques has until now been very expensive. The advent of cheap computing and graphics cards coupled with increasing(More)
Virtual Reality and multimedia technologies are central components of the heritage presentation programme at Ename, Belgium. These techniques are designed to help the visitor understand and experience the past as it has been revealed through archaeological and historical research. This paper briefly traces the development of multimedia and Virtual Reality(More)
This paper expands on the presentation of a methodology that provides a technology-enhanced exhibition of a cultural artefact through the use of a safe hybrid 2D/3D multimodal interface. Such tangible interactions are based on the integration of a 3DOF orientation tracker and information sensors with a 'Kromstaf' rapid prototype replica to provide tactile(More)
For the preservation of cultural heritage to be successful the general public must be able to experience sites and reconstructions in an intuitive, yet convincingly real way. In this paper, a pipeline is discussed that can be employed to generate an interactive presentation of landscape reconstruction through a Quicktime VR object movie. Images of the(More)
