Chapter
This paper describes the results of a case study about how Assisted Navigation and Natural User Interfaces can facilitate user control in virtual architectural walkthroughs and improve the overall experience. This study combines the authors’ previous research in these lines, studying the summed effect of both on a UX test scenario. The installation...

This article presents a novel installation for the development of hybrid physical-numerical flood models in an augmented reality environment. This installation extends the concept introduced by the well-known Augmented Reality-SandBox (AR-Sandbox) module, which presents a more educational, and less research-based and professional application. It co...
Chapter
Architectural objects are composed of multiple and complex, heterogeneous elements. A wall, a floor, a window, are examples of the juxtaposition of several distinct elements that are put together to ensemble a single constructive part. Cross-sections in Architecture are usually made to achieve two different goals. On the one hand, a cross-section o...

Museum installations, especially those related to the display of virtual archaeology, often make use of natural user interaction (NUI). Those sets require methods of interaction that are intuitive and easy to all users, independent of their previous skills and experience with similar or related technologies. The use of depth cameras such as the Kin...
Chapter
Virtual worlds are an environment for the realization of multiple social activities ranging from entertainment to education, economics, or even medicine. Such activities require virtual spaces and buildings for their development and are inhabited by avatars that stand in place of the user. The architecture of these virtual buildings is, for the mos...

Drawing 2D vectorial information over a 3D terrain elevation model is usually performed by real-time rendering to texture. In the case of linear feature representation, there are several specific problems using the texturing approach, specially when using multi-resolution textures. These problems are related to visual quality, aliasing artifacts an...
