Gómez de Segura, José DanielFernández, BorjaPeral, RosaLópez, SusanaIbáñez, Eduardo2015-11-122015-11-1220031017-4656https://doi.org/10.2312/egp.20031017This paper describes the demo associated to one of our projects, which is currently under development. The version presented can be considered as a large terrain simulation over the Basque Country area (North of Spain), with real imagery, georeferenced information and a user friendly and interactive interface. The main goal is to demonstrate the applications of virtual reality techniques to fields such as virtual tourism, low cost simulators or edutainment. The requirements of the demo are low enough for it to be run in a home PC with a middle range graphics accelerator card. Currently, there are some OpenGL optimisations specific to NVIDIA chipsets and consequently this platform has a slight advantage in terms of performance.
