This paper presents the first prototype of an interactive visualisation framework specifically designed for presenting geographical information in both indoor and outdoor environments. The input of our system is ESRI Shapefiles which represent 3D building geometry and landuse attributes. Participants can visualise 3D reconstructions of geographical(More)
In this paper, we propose the use of specific system architecture, based on mobile device, for navigation in urban environments. The aim of this work is to assess how virtual and augmented reality interface paradigms can provide enhanced location based services using real-time techniques in the context of these two different technologies. The virtual(More)
Up to now most attempts to develop pedestrian navigation tools for the urban environment have used GPS technologies to display position on two-dimensional digital maps (as in the classic 'satnav' systems on the market). Although GPS is the key technology for location-based services (LBS), it cannot currently meet all the requirements for navigation in urban(More)
In this paper we propose the use of specific mobile system architecture for navigation in urban environments. The aim of this work is to evaluate how virtual and augmented reality interfaces can provide location and orientation-based services using different technologies. The virtual reality interface is entirely based on sensors to detect the location and(More)
While traditional computer graphics research to this day still focuses on the production and assessment of photorealism, a relatively new field, the one of nonphotorealistic rendering (NPR), has produced results that focus on viewer engagement by the use of stylization, abstraction and expressiveness. In this paper we briefly describe some of the techniques(More)
This paper presents a comprehensive procedural 3D modelling solution called Virtual City Maker, which relies on scripting algorithms for automatic generation of photorealistic virtual urban content. This solution uses the combination of aerial images, terrestrial photographic input and 2D ground maps in conjunction with a user-friendly customized interface(More)
This paper presents research and development of a dedicated system architecture, designed to enable its users to interact with each other as well as to access information on points of interest that exist in their immediate environment. This is accomplished through managing personal preferences and contextual information in a distributed manner and in real(More)
This paper discusses alternative approaches for interacting with virtual reality models on mobile devices, based upon work conducted as part of the locus project [6]. First, mobile virtual reality models are discussed within the established realityvirtuality continuum to demonstrate how this new mixed reality paradigm compares with augmented and virtual(More)

Rapid procedural 3D urban modelling has been a constant research issue for a number of years now. We present a complete procedural 3D modelling solution for mobile device usage of the content, called Virtual City Maker, based on scripting algorithms allowing for both the automatic and also semi-automatic creation of photorealistic quality virtual urban(More)
