Contact: Besuievsky, Gonzalo
Financing institution: Universitat de Girona
Period: 01-06-2016 / 31-12-2018
Els models urbans són sistemes geomètrics complexos necessaris per a l’anàlisi en aplicacions de diversos dominis, com ara la simulació ambiental, la planificació urbana o la visualització de dades urbanes. La generació d’aquests models de forma robusta i precisa per diferents propòsits és un repte. L’ objectiu principal d’aquest projecte es el de desenvolupar nous mètodes per a la generació de models urbans adequats per a diversos tipus de simulació. Així mateix, els models de simulació existents seran adaptats pel ús eficient en models urbans complexos. Els àmbits de simulació en que es treballarà seran: avaluació energètica (anàlisis tèrmic i lumínica), modelat de degradació temporal de materials urbans i anàlisi d’evolució temporal dels canvis urbans. A banda de la robustesa dels models i la seva flexibilitat pels propòsits de simulació, també es buscarà desenvolupar noves interfícies d’usuari per a la generació i edició del models, donant a l’usuari la capacitat de modificar interactivament i de forma natural els components del paisatge urbà.

Financing institution: Spanish "Ministerio de Economia y Competitidad", TIN2010-20590-C02
Period: 01-01-2011 / 31-07-2014
This project is the framework of the ViRVIG research. It is concerned with improving the efficiency so that higher quality renderings become available for complex models at the demanding speed needed by stereo applications and mobile architectures, with enhanced, specially tailored interaction mechanisms, and with obtaining improved geometric data mining algorithms to facilitate operating on these datasets. Although these problems are of a fundamental nature, we find it advisable to focus on two sufficiently distinct and complementary applications to both serve as guides and concept-demonstrators: the modelling of large urban environments and the handling of volumetric models in medicine.

Period: 14-12-2012 / 13-12-2013
The understanding and simulation of the temporal evolution of urban environments is crucial not only for historical studies, but also for urban planning in modern cities. This proposal presents urbanEvolution, a project that aims to develop the first techniques ever for a user-controlled, automatic study of the evolution of buildings and whole cities over time. This study is expected to be done through the definition of urban states, which are procedural snapshots of the structure of an architectural or urban element; and operators, which produce discrete evolutions in these states into new ones reflecting the changes over time.

High-Performance Multi-Projector CAVE System
Contact: Brunet, Pere
Financing institution: ViRVIG
Period: 01-02-2009 / 30-04-2013
The goal of this project has been the design and construction of a novel, four wall multi- projector CAVE VR system which is powered by 40 off-the-shelf projectors controlled by 12 PCs. It operates in passive stereo, providing high brightness at 2000 x 2000 pixel resolution on each of the 4 walls. We have achieved high resolution while significantly reducing the cost and increasing versatility: the system works with any mix of a wide range of projector models that can be substituted at any moment for more modern or cheaper ones. The uniformity of the final image is achieved using a specially designed self-calibration software which adapts each of the 40 projectors and guarantees concordance and continuity. The system includes a gesture-based interaction approach based on a clever combination of skeletal data from multiple Kinect sensors. Interaction is intuitive and cableless.

Widespread uptake of HDR requires common interface standards. Currently they do not exist. There are isolated pockets of high-quality HDR endeavour across Europe, but not a co-ordinated approach. 2009 saw the appearance the first commercial HDR display and the world’s first HDR video camera. These European-led developments reinforce the timeliness of developing HDR standards and the special position Europe is in to lead the rapid acceleration of future HDR developments and market penetration. This COST Action (HDRi) assembles leading academic and industrial researchers and practitioners to propose a set of standards for the complete HDR pipeline and establish Europe firmly as the world leader in HDR.

Financing institution: Ministerio Español de Educación y Ciencia.
Period: 01-04-2009 / 31-03-2011
We propose to explore a new approach to create high-dynamic range content with physically accurate radiance values from multi-exposed photographs. Accurate radiance values haven’t been so far ensured by previous methods but are crucial for research in illumination for mixed reality, image processing and photogrammetry. Our aim is to address a wide range of cameras and scene contents, including uncontrollable environments, such as exterior scenes with pedestrians or vegetation subject to wind. This involves solving ill-posed mathematical problems that are extremely difficult to solve, on uncontrollable data. Solutions should be as automatic and as free from user intervention as possible.

Presence: Research Encompassing Sensory Enhancement, Neuroscience, Cerebral-Computer Interfaces and Applications This Integrated Project will undertake a Research Programme that has as its major goal the delivery of presence in wide area distributed mixed reality environments. The environment will include a physical installation that people can visit both physically and virtually. The installation will be the embodiment of an artificial intelligent entity that understands and learns from its interaction with people. People who inhabit the installation will at any one time be physically there, virtually there but remote, or entirely virtual beings with their own goals and capabilities for interacting with one another and with embodiments of real people. Specific subclasses of the installation will be used for the construction of a number of application scenarios, such as a persistent virtual community that embodies the project itself. The core methodology will be to achieve this through the identification, understanding and exploitation of cerebral mechanisms for presence in conjunction with advances in the underlying technology for mixed reality display and interaction, with special attention to the interaction between people, and also between people and virtual people. Such cerebral mechanisms will be the basis for a core aspect of the IP which is the exploitation of brain-computer interfaces. Processes within the environments adapt and correlate with the behaviour and state of people, and in addition people are able to effect changes within the environment through thought as well as through motor actions.
