Article
Accés obertVirtual reality applications depend on multiple factors, for example, quality of rendering, responsiveness, and interfaces. In order to evaluate the relative contributions of different factors to quality of experience, ... -
Exploiting the potential of image based crowd rendering
Izquierdo, Maria; Beacco Porres, Alejandro; Pelechano Gómez, Núria; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2015)
Comunicació de congrés
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 ... -
Footstep parameterized motion blending using barycentric coordinates
Beacco Porres, Alejandro; Pelechano Gómez, Núria; Kapadia, Mubbasir; Badler, Norman (2015-04-01)
Article
Accés obertThis paper presents a real-time animation system for fully embodied virtual humans that satisfies accurate foot placement constraints for different human walking and running styles. Our method offers a fine balance between ... -
Impostor-based crowd rendering
Beacco Porres, Alejandro; Pelechano Gómez, Núria; Andújar Gran, Carlos Antonio (CRC Press, 2016-09-27)
Capítol de llibre
Accés restringit per política de l'editorialReal-time rendering of detailed animated characters in crowd simulations is still a challenging problem in computer graphics. State-of-the-art approaches can render up to several thousand agents by consuming most of the ... -
La realidad virtual en el aprendizaje de historia mediante la interacción con humanoides virtuales

Text en actes de congrés
Accés restringit per política de l'editorialRendering detailed animated characters is a major limiting factor in crowd simulation. In this paper we present a new representation for 3D animated characters which supports output-sensitive rendering. Each character is ... -
Output-Sensitive Rendering of Detailed Animated Characters for Crowd Simulation
Beacco Porres, Alejandro (Universitat Politècnica de Catalunya, 2010-06)
Projecte Final de Màster Oficial
Accés obertHigh-quality, detailed animated characters are often represented as textured polygonal meshes. The problem with this technique is the high cost that involves rendering and animating each one of these characters. This problem ... -
