Locally-adaptive texture compression
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialCurrent schemes for texture compression fail to exploit spatial coherence in an adaptive manner due to the strict efficiency constraints imposed by GPU-based, fragment-level decompression. In this paper we present a texture ... -

MDCO to B-Rep conversion algorithm
(1995-07)
Report de recerca
Accés obertSpatial enumeration models are widely used in several fields. These models are approximate but the major disadvantage is the lack of concision. In order to avoid such verbosity, hierarchical encodings such as octrees have ... -
Mesh repair with user-friendly topology control
(Elsevier, 2011-01)
Article
Accés restringit per política de l'editorialLimitations of current 3D acquisition technology often lead to polygonal meshes exhibiting a number of geometrical and topological defects which prevent them from widespread use. In this paper we present a new method for ... -
MeshPipe: a Python-based tool for easy automation and demonstration of geometry processing pipelines
(Scitepress, 2020)
Text en actes de congrés
Accés obertThe popularization of inexpensive 3D scanning, 3D printing, 3D publishing and AR/VR display technologies have renewed the interest in open-source tools providing the geometry processing algorithms required to clean, repair, ... -
Multi-scale manipulation in indoor scenes with the World in Miniature Metaphor
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialThe World in Miniature Metaphor (WIM) allows users to select, manipulate and navigate efficiently in virtual environments. In addition to the first-person perspective offered by typical VR applications, the WIM offers a ... -
Neural colorization of laser scans
(European Association for Computer Graphics (Eurographics), 2021)
Text en actes de congrés
Accés obertLaser scanners enable the digitization of 3D surfaces by generating a point cloud where each point sample includes an intensity (infrared reflectivity) value. Some LiDAR scanners also incorporate cameras to capture the ... -
NightLighting: a nocturnal urban illumination approach
(European Association for Computer Graphics (Eurographics), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialReal time rendering of cities with realistic global illumination is still an open problem. In this paper we propose a two-step algorithm to simulate the nocturnal illumination of a city. The first step computes an approximate ... -
Omni-directional relief impostors
(North Holland, 2007-07)
Article
Accés restringit per política de l'editorialRelief impostors have been proposed as a compact and high-quality representation for high-frequency detail in 3D models. In this paper we propose an algorithm to represent a complex object through the combination of ... -

Relief impostor selection for large scale urban rendering
(2008)
Comunicació de congrés
Accés obertImage-based rendering techniques are often the preferred choice to accelerate the exploration of massive outdoor models and complex human-made structures. In the last few years, relief mapping has been shown to be extremely ... -
Relief mapping on cubic cell complexes
(2010)
Text en actes de congrés
Accés obertIn this paper we present an algorithm for parameterizing arbitrary surfaces onto a quadrilateral domain defined by a collection of cubic cells. The parameterization inside each cell is implicit and thus requires storing ... -
