    A Virtual Reality Front-end for City Modeling
    (The Eurographics Association, 2019) Rando, Eduard; Andujar, Carlos; Patow, Gustavo A.; Casas, Dan and Jarabo, Adrián
    Current tools for city modeling, including those supporting procedural techniques, have a steep learning curve and require substantial user input and/or skills to create realistic 3D models of cities. In this paper we propose a VR tool for the fast and intuitive creation of 3D models of cities through their main elements (buildings, blocks and streets). The key ingredients of our approach are: (a) intuitive creation of mass volume models for buildings, whose facades can be refined later on through procedural rules, (b) the ability to use arbitrary urban layouts, either created from scratch within the tool or imported from public map services, (c) algorithms to replicate and transfer user-generated blocks to arbitrary block shapes, so that a few template blocks suffice to cover the whole urban layout. The major benefit of our approach is that city design and inspection tasks are done simultaneously in a completely immersive environment.

    A Virtual Reality Front-End for Earthquake Simulation
    (The Eurographics Association, 2019) Fita, Josep Lluis; Besuievsky, Gonzalo; Patow, Gustavo A.; Casas, Dan and Jarabo, Adrián
    Virtual Reality has traditionally been used in Cultural Heritage for giving to the final user an immersive experience over recreated scenarios, which usually have been designed and focused on static environment recreation. In spite of its importance for cultural heritage, we have found a lack of virtual reality applications to recreate structural and seismic simulations on historical buildings. In this paper we describe a low-cost virtual reality solution, affordable for all kinds of users that own a smart-phone. Through our application, the users can have an immersive experience that combines the ancient building recreation, its structural simulation and the natural phenomena simulation like earthquakes.
