Accés restringit per política de l'editorialPer-joint impostors have been used to achieve high performance when rendering thousands of agents, while still allowing us to blend animation. This provides interactively animated crowds and reduces the memory footprint ... -
First impressions: A survey on vision-based apparent personality trait analysis
(Institute of Electrical and Electronics Engineers (IEEE), 2022-01-01)
Article
Accés obertPersonality analysis has been widely studied in psychology, neuropsychology, and signal processing fields, among others. From the past few years, it also became an attractive research area in visual computing. From the ... -
Friction surfaces: scaled ray-casting manipulation for interacting with 2D GUIs
(2006-05-17)
Text en actes de congrés
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 ... -
Gain compensation across LIDAR scans
(2022-08)
Article
Accés obertHigh-end Terrestrial Lidar Scanners are often equipped with RGB cameras that are used to colorize the point samples. Some of these scanners produce panoramic HDR images by encompassing the information of multiple pictures ... -
Geometry simplification
(1999-02)
Report de recerca
Accés obertIn this work we present the principles and applications of geometry simplification, focusing on simplification of polygonal representations of solids and surfaces. Related concepts such as multiresolution, level-of-detail ... -
GL-Socket: A CG plugin-based framework for teaching and assessment
(European Association for Computer Graphics (Eurographics), 2018)
Text en actes de congrés
Accés obertIn this paper we describe a plugin-based C++ framework for teaching OpenGL and GLSL in introductory Computer Graphics courses. The main strength of the framework architecture is that student assignments are mostly independent ... -
Image-based tree variations
