Structural stability of planar bimodal linear systems
(2014-01-01)
Article
Accés obertStructural stability ensures that the qualitative behavior of a system is preserved under small perturbations. We study it for planar bimodal linear dynamical systems, that is, systems consisting of two linear dynamics ... -
Robust treatment of degenerate elements in interactive corotational FEM simulations
(2014-09-01)
Article
Accés restringit per política de l'editorialWe address the problem of robust and efficient treatment of element collapse and inversion in corotational FEM simulations of deformable objects in two and three dimensions, and show that existing degeneration treatment ... -
Anisomorphic ray-casting manipulation for interacting with 2D GUIs
(2007-01)
Article
Accés obertThe accommodation of conventional 2D GUIs with virtual environments (VEs) can greatly enhance the possibilities of many VE applications. In this paper we present a variation of the well-known ray-casting technique for fast ... -

Interactive visualization of medical volume models in mobile devices
(2013-10)
Article
Accés restringit per política de l'editorialInteractive visualization of volume models in standard mobile devices is a challenging present problem with increasing interest from new application fields like telemedicine. The complexity of present volume models in ... -
Adaptive cross-sections of anatomical models
(North-Holland, 2012-09)
Article
Accés restringit per política de l'editorialMedical illustrations have been used for a long time for teaching and communicating information for diagnosis or surgery planning. Illustrative visualization systems create methods and tools that adapt traditional illustration ... -
Mechanisms of abdominal distension in severe intestinal dysmotility: abdomino-thoracic response to gut retention
(2013)
Article
Accés restringit per decisió de l'autorBACKGROUND: We previously showed that abdominal distension in patients with functional gut disorders is due to a paradoxical diaphragmatic contraction without major increment in intraabdominal volume. Our aim was to ... -
The ViRVIG institute
(2011-11-16)
Article
Accés obertIn this paper we present the ViRVIG Institute, a recently created institution that joins two well-known research groups: MOVING in Barcelona, and GGG in Girona. Our main research topics are Virtual Reality devices and ... -
Avatar locomotion in crowd simulation
(2011-03)
Article
Accés restringit per política de l'editorialThis paper presents an Animation Planning Mediator (APM) designed to synthesize animations efficiently for virtual characters in real time crowd simulation. From a set of animation clips, the APM selects the most appropriate ... -
Efficient rendering of animated characters through optimized per-joint impostors
(2012-02)
Article
Accés restringit per política de l'editorialIn this paper, we present a new impostor-based representation for 3D animated characters supporting real-time rendering of thousands of agents. We maximize rendering performance by using a collection of pre-computed ... -
Hybrid Rugosity Mesostructures (HRMs) for fast and accurate rendering of fine haptic detail
(Centro Latinoamericano de Estudios en Informática, 2010)
Article
Accés obertThe haptic rendering of surface mesostructure (fine relief features) in dense triangle meshes requires special structures, equipment, and high sampling rates for detailed perception of rugged models. Low cost approaches ... -
World-in-miniature interaction for complex virtual environments
(IGI Global, 2010-12)
Article
Accés obertObject occlusion is a major handicap for efficient interaction with 3D virtual environments. The well-known World in Miniature (WIM) metaphor partially solves this problem by providing an additional dynamic view point ...
