3D Skeletons: A State-of-the-Art Report
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Given a shape, a skeleton is a thin centered structure which jointly describes the topology and the geometry of the shape. Skeletons provide an alternative to classical boundary or volumetric representations, which is ... -
3D Sketch Recognition for Interaction in Virtual Environments
(The Eurographics Association, 2010)We present a comprehensive 3D sketch recognition framework for interaction within Virtual Environments that allows to trigger commands by drawing symbols, which are recognized by a multi-level analysis. It proceeds in three ... -
The 3D Sketch Slice: Precise 3D Volume Annotations in Virtual Environments
(The Eurographics Association, 2009)In the oil and gas application domain, there is a need for 3D volume annotations to sketch out uncertainty regions in seismic data sets. Together with geo-science experts, we identified actual requirements for efficient ... -
3D Sketch-Based 3D Shape Retrieval
(The Eurographics Association, 2016)Sketch-based 3D shape retrieval has unique representation availability of the queries and vast applications. Therefore, it has received more and more attentions in the research community of content-based 3D object retrieval. ... -
3D Sketching for Interactive Model Retrieval in Virtual Reality
(ACM, 2018)We describe a novel method for searching 3D model collections using free-form sketches within a virtual environment as queries. As opposed to traditional sketch retrieval, our queries are drawn directly onto an example ... -
3D Sketching with Fully Free Form Deformation Features (d-F4) for Aesthetic Design
(The Eurographics Association, 2004)This paper addresses the designers activity and in particular the way designers express an object shape in 2D sketches through character lines. The tools currently available in commercial CAS/CAD systems to manipulate the ... -
3D Soft Segmentation and Visualization of Medical Data Based on Nonlinear Diffusion and Distance Functions
(The Eurographics Association, 2006)Visualization of medical 3D data is a complex problem, since the raw data is often unsuitable for standard techniques like Direct Volume Rendering. Some kind of pre-treatment is necessary, usually segmentation of the ... -
3D Sound for Digital Cultural Heritage
(The Eurographics Association, 2021)Virtual Reality enables the users to experience cultural heritage. Time travel through past times is transferring us in virtual environments with 3D reconstructions of cultural monuments inhabited by historical characters. ... -
3D Strokes on Visible Structures in Direct Volume Rendering
(The Eurographics Association, 2013)In this paper we describe VisiTrace, a novel technique to draw 3D lines in direct volume rendered images. It allows to draw strokes in the 2D space of the screen to produce 3D lines that run on top or in the center of ... -
3D Surface Reconstruction Using a Generalized Distance Function
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We define a generalized distance function on an unoriented 3D point set and describe how it may be used to reconstruct a surface approximating these points. This distance function is shown to be a Mahalanobis distance in ... -
3D Timeline: Reverse Engineering of a Part-based Provenance from Consecutive 3D Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel tool for reverse engineering of modeling histories from consecutive 3D files based on a timeline abstraction. Although a timeline interface is commonly used in 3D modeling packages for animations, it has ... -
3D User Interfaces Using Tracked Multi-touch Mobile Devices
(The Eurographics Association, 2012)Multi-touch mobile devices are becoming ubiquitous due to the proliferation of smart phone platforms such as the iPhone and Android. Recent research has explored the use of multi-touch input for 3D user interfaces on ... -
3D VAE-Attention Network: A Parallel System for Single-view 3D Reconstruction
(The Eurographics Association, 2018)3D object reconstruction from single view image is a challenge task. Due to the fact that the information contained in one isolated image is not sufficient for reasonable 3D shape reconstruction, the existing results on ... -
3D Video Billboard Clouds
(The Eurographics Association and Blackwell Publishing Ltd, 2007)3D video billboard clouds reconstruct and represent a dynamic three-dimensional scene using displacement-mapped billboards. They consist of geometric proxy planes augmented with detailed displacement maps and combine the ... -
3D Video Recorder: a System for Recording and Playing Free-Viewpoint Video?
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present the 3D Video Recorder, a system capable of recording, processing, and playing three-dimensional video from multiple points of view. We first record 2D video streams from several synchronized digital video cameras ... -
3D Video: from Capture to Diffusion
(The Eurographics Association, 2014)While 3D vision has existed for many years, the use of 3D cameras and video-based modeling by the film industry has induced an explosion of interest for 3D acquisition technology, 3D content and 3D displays. As such, 3D ... -
3D Video: from Capture to Interactive Display
(The Eurographics Association, 2015)While 3D vision and 3D/4D imaging has existed for many years, the use of 3D cameras and video-based modeling by the film industry and recent access to cheap contactless control devices has induced an explosion of interest ... -
3D virtual facial reconstruction and visualization of ancient Egyptian mummies using spiral CT data
(Eurographics Association, 1999)The problem of rebuilding a face from human remains has been, until now, especially relevant in the ambit of forensic sciences, where it is obviously oriented toward the identification of otherwise unrecognizable corpses; ... -
A 3D Visualisation Environment Modelling the Evolution of North-West Europe since the Last Glacial Maximum
(The Eurographics Association, 2007)This work in progress aims to provide an interactive 3D visualisation allowing real time manipulation of glacial isostatic adjustment (GIA) model output data which reconstructs the ice distribution and coastline position ... -
