Online 3D terrain visualization: A comparison of three different GIS software

In recent times, the online 3D terrain visualization has created much interest in many applications such as land information system, military, environmental, tourism and mapping science.Many systems such as CityGML,Terraserver, Google Earth and Spaceye3D have successfully adopted this technology in their system for different applications.The aim of this paper is to compare the effectiveness of developing online 3D terrain visualization by using three popular GIS Software; R2V, Arc View 3.2 and Arc GIS 9.2. In this paper, we implement the system based on the Digital Elevation Model (DEM) and Triangulated Irregular Network (TIN) for the terrain data and then overlay with satellite image. Finally, the effectiveness of online 3D terrain rendering in terms of terrain visualization quality, file size, and loading time are made to compare the quality of the systems.The results help the developers on finding the right software to be used for their online 3D terrain visualization

The development and applications of serious games in the public services: defence and health

This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University London.The latest advances of Virtual Reality technologies and three-dimensional graphics, as well as the developments in Gaming Technologies in the recent years, have stemmed the proliferation of Serious Games in a broader spectrum of research applications. Among the most popular areas of application are public services such as Defence and Health, where digital technologies realise new challenges and opportunities for research and development of Serious Games and for a variety of contexts. As with all games, the user engagement is elevated and apart from the entertaining aspect, Serious Games serve as a novel and promising alternative experience to knowledge transfer. Furthermore, Serious Games bring to the end user and the overall society a series of attractive benefits. These benefits include safety, cost-effectiveness, increased motivation and personalisation. Hence, this Thesis aims to investigate novel approaches of developing Serious Games that utilise the recent advances of Virtual Reality and Gaming Technology and facilitate the aforementioned benefits. The process of design and development of the novel tools and applications follow an iterative manner and are driven by the review of the available literature as well as end-user feedbackEPSRC (Engineering and Physical Sciences Research Council ) , MOD (UK), NHS (UK
