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)
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)
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 work presents our experience in using Virtual Reality techniques to digitally reconstruct the downtown of São Paulo city in the year of 1911. Particularly, the reconstruction of old downtown São Paulo could bring relevant information regarding its culture, history and economy. In order to achieve an accurate 3D representation, the process was divided(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)
