(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 near field 3D radar imaging technique
(Institute of Electrical and Electronics Engineers (IEEE), 1993)
Text en actes de congrés
Accés obertThe paper presents an algorithm which recovers a 3D reflectivity image of a target from near-field scattering measurements. Spherical wave nearfield illumination is used, in order to avoid a costly compact range installation ... -
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 platform for developing and fine tuning adaptive 3D navigation techniques for the immersive web
(Association for Computing Machinery (ACM), 2021)
Text en actes de congrés
Accés obertNavigating through a virtual environment is one of the major user tasks in the 3D web. Although hundreds of interaction techniques have been proposed to navigate through 3D scenes in desktop, mobile and VR headset systems, ... -
A portable three-dimensional object slicer
(Universitat Politècnica de Catalunya, 2019-06-27)
Treball Final de Grau
Accés obertOpenSlicer is a portable three-dimensional object slicer. Its purpose is to be run in a web browser, possibly on mobile devices, as a convenient way to 3D print objects without needing a computer. -
A Study of Osona's Medieval Castles
(Universitat Politècnica de Catalunya, 2017-07-18)
Treball Final de Grau
Accés obertSince ancient times, humans have been fascinated with past cultures. Unlike other material culture, getting hold of the architectural legacy of past civilizations is often difficult, as buildings have been demolished, build ... -
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 ... -

Accurate molecular atom selection in VR
(European Association for Computer Graphics (Eurographics), 2022)
Comunicació de congrés
Accés obertAccurate selection in cluttered scenes is complex because a high amount of precision is required. In Virtual Reality Environments, it is even worse, because it is more difficult for us to point a small object with our arms ... -
Accurate molecular atom selection in VR
(European Association for Computer Graphics (Eurographics), 2022)
Text en actes de congrés
Accés obertTarget acquisition is a basic task that is part of almost any high-level interaction in 3D environments. Therefore, providing accurate selection is a necessity for most applications and games. When targets are small and ... -
Adaptive approximation of signed distance fields through piecewise continuous interpolation
(Elsevier, 2023-08)
Article
Accés obertIn this paper, we present an adaptive structure to represent a signed distance field through trilinear or tricubic interpolation of values, and derivatives, that allows for fast querying of the field. We also provide a ... -
