3D texture-based hybrid visualizations
(2003-01)
Article
Accés restringit per política de l'editorialIn this paper, the visualization of hybrid scenes that contain volume data and a fitted extracted surface is addressed. The proposed algorithm is based on a integrated octree-based representation: the ‘‘hybrid octree.’’ ... -
A 3D System for training in endoscopical repair of subcondylar fractures of the mandible
(Springer Verlag, 2008)
Article
Accés obertPoster Session: 12th Annual Conference of Iscas. Conventional treatment of the subcondylar fractures of the mandible is challenging because of the medial and anterior displacement of the condylar fragment and the limited ... -
A 3D virtual model for training in endoscopical repair of subcondylar fractures of the mandible
(2008-09)
Article
Accés restringit per política de l'editorialConventional treatment of the subcondylar fractures of the mandible is challenging because of the medial and anterior displacement of the condylar fragment and the limited surgical field. Proximity of facial nerve, carotid ... -
A cost-effective approach for developing application-control GUIs for virtual environments
(2006-03)
Comunicació de congrés
Accés obertIn this paper we present a new approach for fast development of application-control User Interfaces (UIs) for Virtual Environments (VEs). Our approach allows developers to build sophisticated UIs containing both simple ... -
A framework for rendering, simulation and animation of crowds
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialReal-time crowd simulation for virtual environment applications requires not only navigation and locomotion in large environments while avoiding obstacles and agents, but also rendering high quality 3D fully articulated ... -
A generalized exact arbitrary clearance technique for navigation meshes
(ACM, 2013)
Text en actes de congrés
Accés obertThere are two frequent artifacts in crowd simulation, the first one appears when all agents attempt to traverse the navigation mesh sharing the same way point over portals, increasing the probability of collision against ... -
A grid representation for distributed virtual environments
(2004)
Text en actes de congrés
Accés restringit per política de l'editorialFast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environments (DVE) very common nowadays. The architecture and behavior of these systems are very similar to ... -
A hybrid rugosity mesostructure (HRM) for faster rendering of fine haptic detail
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialWe propose a faster method for surface haptic rendering using image-based Hybrid Rugosity Mesostructures (HRMs), paired maps with per-face height eld displacements and normalmaps, which are layered on top of a much decimated ... -
A mesh-particle model for fluid animation
(2006)
Text en actes de congrés
Accés restringit per política de l'editorialWe use our adapted versions of the two most used methods in Computer Fluid Animation, Marker and Cell and Smoothed Particle Hydrodynamics, to develop a new method taking advantage of the calculation speed of the first and ... -
A parametric-space-based scan-line algorithm for rendering of bicubic surfaces
(1987)
Article
Accés obertA novel scan-line algorithm for displaying bicubic surfaces is presented. Patches are decomposed on regions of constant sign of the z component of the normal before the scan process. Most of the computations are done in ... -
A topological comparison of surface extraction algorithms
(2006-01)
Report de recerca
Accés obertIn many application areas, it is useful to convert the discrete information stored in the nodes of a regular grid into a continuous boundary model. Isosurface extraction algorithms di er on how the discrete information in ... -
A Virtual Reality approach to progressive lenses simulation
(2005)
Text en actes de congrés
Accés restringit per política de l'editorialProgressive lenses are lenses that allow focusing objects at any distance. The main problem of these lenses is the arise of marginal zones that present aberrations in which vision is defective. The interest of our research ... -
A Volume Visualization Algorithm using a coherent Extended Weight Matrix
(1995-01)
Article
Accés restringit per política de l'editorialDirect cell-to-cell volume visualization algorithms, also called projective rendering methods, present the advantage of allowing semi-transparencies and, additionally, as they project all the samples, they avoid the ... -
Accurate multi-modal image registration using compression
(IADIS Press, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialImage registration is an important task in medicine, especially when images have been acquired by different scanner/sensor types, since they provide information on different body structures (bones, muscles, vessels...). ... -
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 ... -
Adjusting animation rings to human-like 3D models
(2010)
Article
Accés restringit per política de l'editorialIn the animation process of a human-like 3D model, a skeleton must be specified to define the model’s surface deformation of its limbs. Nowadays the skeleton specification is hand made and very time consuming task. In ... -
Affordable immersive projection system for 3d interaction
(SIACG, 2002)
Text en actes de congrés
Accés obertThis paper describes an affordable Virtual Reality system designed and developed by a group of researchers at the Polytechnic University of Catalunya (UPC). The system allows direct selection and manipulation of virtual ... -
An interactive 3D framework for anatomical education
(2008-12)
