Rendering piecewise approximations of SDFs through analytic intersections
(Elsevier, 2024-08)
Article
Open AccessSigned distance fields (SDFs) have emerged as an alternative shape representation for real-time collision detection and lighting effects. Computing these for complex models can be expensive, so one popular approach is to ... -

(Springer, 2024-06-12)
Article
Open AccessIn this paper, we discuss the requirements and technical challenges within the EHEM project, Enhancement of Heritage Experiences: The Middle Ages, an ongoing research program for the acquisition, analysis, documentation, ... -
TRAIL: Simulating the impact of human locomotion on natural landscapes
(Springer, 2024-06-05)
Article
Open AccessHuman and animal presence in natural landscapes is initially revealed by the immediate impact of their locomotion, from footprints to crushed grass. In this work, we present an approach to model the effects of virtual ... -
DeadWood: Including disturbance and decay in the depiction of digital nature
(2024-02-14)
Article
Open AccessThe creation of truly believable simulated natural environments remains an unsolved problem in Computer Graphics. This is, in part, due to a lack of visual variety. In nature, apart from variation due to abiotic and biotic ... -
A 3D feature-based approach for mapping scaling effects on stone monuments
(Association for Computing Machinery (ACM), 2024-04-17)
Article
Open AccessWeathering effects caused by physical, chemical, or biological processes result in visible damages that alter the appearance of stones’ surfaces. Consequently, weathered stone monuments can offer a distorted perception of ... -
Simulating real-life scenarios to better understand the spread of diseases under different contexts
(Springer, 2024-02-01)
Article
Open AccessCurrent statistical models to simulate pandemics miss the most relevant information about the close atomic interactions between individuals which is the key aspect of virus spread. Thus, they lack a proper visualization ... -
PADELVIC: Multicamera videos and motion capture data in padel matches
(2024)
Article
Open AccessRecent advances in computer vision and deep learning techniques have opened new possibilities regarding the automatic labeling of sport videos. However, an essen-tial requirement for supervised techniques is the availability ... -
The making of a newspaper interview in virtual reality: realistic avatars, philosophy, and sushi
(2023-11)
Article
Open AccessVR United is a virtual reality application that we have developed to support multiple people simultaneously interacting in the same environment. Each person is represented with a virtual body that looks like themselves. ... -
SparsePoser: Real-time full-body motion reconstruction from sparse data
(2023-10-31)
Article
Open AccessAccurate and reliable human motion reconstruction is crucial for creating natural interactions of full-body avatars in Virtual Reality (VR) and entertainment applications. As the Metaverse and social applications gain ... -
Automated virtual reality cognitive therapy versus virtual reality mental relaxation therapy for the treatment of persistent persecutory delusions in patients with psychosis (THRIVE): a parallel-group, single-blind, randomised controlled trial in England with mediation analyses
(Elsevier, 2023-09)
Article
Open AccessBackground: Persecutory delusions are a major psychiatric problem that often do not respond sufficiently to standard pharmacological or psychological treatments. We developed a new brief automated virtual reality (VR) ... -

(Elsevier Ltd, 2023-10)
Article
Open AccessPublic Bicycle Sharing Systems have spread in many cities for the last decade. The need of analysis tools to predict the behavior or estimate balancing needs has fostered a wide set of approaches that consider many variables. ... -
GREIL-Crowds: crowd simulation with deep reinforcement learning and examples
(2023-08)
Article
Open AccessSimulating crowds with realistic behaviors is a difficult but very important task for a variety of applications. Quantifying how a person balances between different conflicting criteria such as goal seeking, collision ...
