ViRVIG - Grup de Recerca en Visualització, Realitat Virtual i Interacció Gràfica
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.

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.

Comparing navigation meshes: Theoretical analysis and practical metrics
(2020-10)
Article
Restricted access - publisher's policyA navigation mesh is a representation of a 2D or 3D virtual environment that enables path planning and crowd simulation for walking characters. Various state-of-the-art navigation meshes exist, but there is no standardized ... -
Estimating player positions from padel high-angle videos: Accuracy comparison of recent computer vision methods
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-05-12)
Article
Open AccessThe estimation of player positions is key for performance analysis in sport. In this paper, we focus on image-based, single-angle, player position estimation in padel. Unlike tennis, the primary camera view in professional ... -
Intrinsic-extrinsic convolution and pooling for learning on 3D protein structures
(OpenReview.net, 2021)
Conference lecture
Open AccessProteins perform a large variety of functions in living organisms and thus play a key role in biology. However, commonly used algorithms in protein learning were not specifically designed for protein data, and are therefore ... -
Variable selection in microbiome compositional data analysis
(2020-06-01)
Article
Open AccessThough variable selection is one of the most relevant tasks in microbiome analysis, e.g. for the identification of microbial signatures, many studies still rely on methods that ignore the compositional nature of microbiome ... -
