    • Range Scan Registration Using Reduced Deformable Models 

      Chang, W.; Zwicker, M. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present an unsupervised method for registering range scans of deforming, articulated shapes. The key idea is to model the motion of the underlying object using a reduced deformable model. We use a linear skinning model ...

      The objective of the SHREC'15 Range Scans based 3D Shape Retrieval track is to evaluate algorithms that match range scans of real objects to complete 3D mesh models in a target dataset. The task is to retrieve a rank list ...

    • Rank-1 Lattices for Efficient Path Integral Estimation 

      Liu, Hongli; Han, Honglei; Jiang, Min (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We introduce rank-1 lattices as a quasi-random sequence to the numerical estimation of the high-dimensional path integral. Previous attempts at utilizing rank-1 lattices in computer graphics were very limited to low-dimensional ...

      Schmid, Jenny; Cibulski, Lena; Hazwani, Ibrahim Al; Bernard, Jürgen (The Eurographics Association, 2022)
      Item rankings are useful when a decision needs to be made, especially if there are multiple attributes to be considered. However, existing tools either do not support both categorical and numerical attributes, require ...

    • RankBooster: Visual Analysis of Ranking Predictions 

      Puri, Abishek; Ku, Bon Kyung; Wang, Yong; Qu, Huamin (The Eurographics Association, 2020)
      Ranking is a natural and ubiquitous way to facilitate decision-making in various applications. However, different rankings are often used for the same set of entities, with each ranking method placing emphasis on different ...

    • Rapid Acquisition of Specular and Diffuse Normal Maps from Polarized Spherical Gradient Illumination 

      Ma, Wan-Chun; Hawkins, Tim; Peers, Pieter; Chabert, Charles-Felix; Weiss, Malte; Debevec, Paul (The Eurographics Association, 2007)
      We estimate surface normal maps of an object from either its diffuse or specular reflectance using four spherical gradient illumination patterns. In contrast to traditional photometric stereo, the spherical patterns allow ...

    • Rapid and Accurate Contact Determination between Spline Models using ShellTrees 

      Krishnan, S.; Gopi, M.; Lin, M.; Manocha, D.; Pattekar, A. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this paper, we present an efficient algorithm for contact determination between spline models. We make use of a new hierarchy, called ShellTree, that comprises of spherical shells and oriented bounding boxes. Each ...

    • A Rapid Clustering Algorithm for Efficient Rendering 

      Müller, Gordon; Schäfer, Stephan; Fellner, Dieter W. (Eurographics Association, 1999)
      Hierarchical radiosity using object clusters greatly improves rendering times and reduces memory consumption of radiosity computations. The key feature of the algorithm is using a hierarchy of object clusters to approximate ...

    • Rapid Emission Tomography Reconstruction 

      Chidlow, Ken; Möller, Torsten (The Eurographics Association, 2003)
      We present new implementations of the Maximum Likelihood Expectation Maximization (EM) algorithm and the related Ordered Subset EM (OSEM) algorithm. Our implementation is based on modern graphics hardware and achieves ...

    • Rapid High Quality Compression of Volume Data for Visualization 

      Nguyen, Ky Giang; Saupe, Dietmar (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Volume data sets resulting from, e.g., computerized tomography (CT) or magnetic resonance (MR) imaging modalities require enormous storage capacity even at moderate resolution levels. Such large files may require compression ...

    • Rapid Interactive Modelling from Video with Graph Cuts 

      Hengel, Anton van den; Dick, Anthony; Thormählen, Thorsten; Ward, Ben; Torr, Philip H. S. (The Eurographics Association, 2006)
      We present a method for generating a parameterised model of a scene from a set of images. The method is novel in that it uses information from several sources video, sparse 3D points and user input to fit models to a scene. ...

    • Rapid k-d Tree Construction for Sparse Volume Data 

      Zellmann, Stefan; Schulze, Jürgen P.; Lang, Ulrich (The Eurographics Association, 2018)
      While k-d trees are known to be effective for spatial indexing of sparse 3-D volume data, full reconstruction, e.g. due to changes to the alpha transfer function during rendering, is usually a costly operation with this ...

    • Rapid Modeling of Complex Building Façades 

      Finkenzeller, D.; Schmitt, A. (The Eurographics Association, 2006)
      Architectural settings occur in many virtual environments. Modeling such highly detailed structures manually is a time-consuming and tedious task. Therefore we propose a system for the rapid modeling of building façades. ...
