Upper limb segmentation in egocentric vision is a challenging and nearly unexplored task that extends the well-known hand localization problem and can be crucial for a realistic representation of users’ limbs in immersive and interactive environments, ...

Volumetric segmentation of medical images is an essential tool in treatment planning and many longitudinal studies. While machine learning approaches promise to fully automate it, they most often still depend on manually labeled training data. We thus ...

Navigating 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, 3D navigation still poses a ...

Extended reality (XR) collaboration enables collaboration between physical and virtual spaces. Recent XR collaboration studies have focused on sharing and understanding the overall situation of the objects of interest (OOIs) and its surrounding ambient ...

Combinations of immersive media and graphic portrayals can enable the human subjective sense of Presence. This paper collects our experiences and evaluations from six projects that use Extensible 3D (X3D) interactive graphics to deliver spatial ...

The Extensible 3D (X3D) Graphics Architecture ISO/IEC 19775-1 International Standard version 4.0 is a major release that includes extensive support for version 2.0 of glTF (glTF2), a standard file format for 3D scenes, and models supporting geometry, ...

New standards such as WebXR enable cross-platform VR experiences, relying on the ubiquity of the modern web browser. However, upon measuring performance of WebXR scenes, we found users can suffer from high latency while waiting for all 3D objects ...

Modeling of sound propagation is very important for virtual acoustics and virtual reality applications. For that reason, highly advanced computer models for the prediction of sound fields in rooms have already been proposed. However, most of them are ...

Deviations from the original blueprints could often be found on building sites. To easily identify such constructional modifications, this paper proposes a smart digital twin for construction site monitoring that supports web-based collaboration with ...

Art and culture, at their best, lie in the act of discovery and exploration. This paper describes Resurrect3D, an open visualization platform for both casual users and domain experts to explore cultural artifacts. To that end, Resurrect3D takes two ...

The WebXR Device API allows the creation of web browser-based eXtended Reality (XR) applications, i.e. Virtual Reality (VR) and Augmented Reality (AR) applications, by providing access to input and output capabilities from AR and VR devices. WebXR ...

Through the use of digital placemaking, which combines physical spaces and virtual worlds, downtown locales become incubators for cultural heritage communication, fostering a sense of place attachment and strengthening community engagement. This paper ...

Digital heritage techniques such as photogrammetry and laser scanning are revolutionizing the way we can record, analyze, and disseminate 3D information about cultural heritage sites around the world. However, the expense and expertise required to ...

A UNESCO World Heritage Site, the 4th-Century CE Villa Romana del Casale near Piazza Armerina, Sicily contains the largest collection of mosaics in the Roman world. However, due to accessibility issues (e.g., remote location, weak online presence), the ...

The recent diffusion of new formats of archaeological publication systems results from ad hoc solutions conceived and realized for serving specific communication needs. These new formats are customized for facilitating the fruition of specific ...

The paper aims to describe the tasks that need to be considered when trying to present and publish 3D data with a web viewer in line with the FAIR data principles. For the data to be used further, most 3D models of archaeological objects need to be well ...

The Invisible Heritage – Analysis and Technology (IH-AT) project aimed to design and develop a portal comprised of reliable and efficient technology-ready tools for the visualization, documentation, and analysis of the UNESCO listed churches in the ...

We present our short series of interactive animations on directional derivatives and level curves. This visualisation was developed for students of first-year mathematics courses at the Delft University of Technology. The interactive animation is an ...
