In this paper we present our experience in using Virtual Reality Technologies to accurately reconstruct and further explore ancient and historic city buildings. Virtual reality techniques provide a powerful set of tools to explore and access the history of a city. In order to explore, visualize and hear such history, we divided the process in three phases:(More)
We constructed a personal, spherical, multi-projector perspective-corrected rear-projected display called <i>Spheree.</i> Spheree uses multiple calibrated pico-projectors inside a spherical display with content rendered from a user-centric viewpoint. Spheree uses optical tracking for head-coupled rendering, providing parallax-based 3D depth cues. Spheree is(More)
Virtual Reality procedure training simulators require that users perform actions in a specific order during the procedure. Recent advances in 3D Web technologies, such as Web3D, HTML5 and WebGL, have allowed complex 3D scenes to be rendered interactively, within a web browser. However, designing and implementing a complete VR procedure training application(More)
This project shows a procedure-training simulator targeted at the operation and maintenance of overland distribution power lines. This simulator is focused on workplace safety and risk assessment of common daily operations such as fuse replacement and power cut activities. The training system is implemented using VR goggles (Oculus Rift) and a mixture of a(More)
In this paper we propose an alternative approach to create animations in X3D. This approach allows extended flexibility to control animations during run-time. Among the extended features, it is possible to: control the speed of the animation; play the animation backwards; repeat any specific time interval of the animation and access any key-frame instantly.(More)
