L'activitat de recerca del nostre grup s'inscriu dins la temàtica de la informàtica gràfica (computer graphics) i engloba, de forma complementària, des dels àmbits més fonamentals (geometria computacional, processament de geometria) a les temàtiques relacionades amb els models geomètrics i de volum (estructures jeràrquiques, models discrets, modelització de sistemes molt complexos), la modelització de l'aparença i dels fenomens naturals, la visualització dels models, i les tècniques avançades per a la interacció amb aquests models i per a la seva presentació en entorns de realitat virtual i augmentada, especialment en dispositius de baix cost i en mòbils. El treball coordinat en aquestes àrees genera coneixement transversal en les diferents vessants de la visualització interactiva, amb aplicació directa a camps com la modelització d'entorns rurals i urbans, l'anàlisi visual aplicat a medicina, la simulació de multituds o la preservació del territori i del patrimoni cultural.

La actividad de investigación de nuestro grupo se inscribe dentro de la temática de la informática gráfica (computer graphics) y engloba, de forma complementaria, desde los ámbitos más fundamentales (geometría computacional, procesamiento de geometría) a las temáticas relacionadas con los modelos geométricos y de volumen (estructuras jerárquicas, modelos discretos, modelización de sistemas muy complejos), la modelización de la apariencia y de los fenómenos naturales, la visualización de los modelos, y las técnicas avanzadas para la interacción con estos modelos y para su presentación en entornos de realidad virtual y aumentada, especialmente en dispositivos de bajo coste y en móviles. El trabajo coordinado en estas áreas genera conocimiento transversal en las diferentes vertientes de la visualización interactiva, con aplicación directa en campos como la modelización de entornos rurales y urbanos, el análisis visual aplicado a medicina, la simulación de multitudes o la preservación del territorio y del patrimonio cultural.

The group focuses on research in modelling, visualisation and advanced graphics interaction and its application to virtual reality. The group's objectives are the following:
- To produce high-quality research results in the areas of visualisation, geometric and volumetric modelling, physically based animation, virtual reality and advanced interaction.
- To train new researchers and doctoral students in these areas.
- To foster and maintain strong international cooperation.
- To work on relevant research projects funded by various institutions (EU, CICYT, etc.)
- To transfer the results of the group?s research and VR applications (virtual prototypes for industrial design, medical applications, architecture, cultural heritage, low-cost VR systems, etc.) to industry and other organisations.
