    • Using Augmented Reality as a Medium to Assist Teaching in Higher Education 

      Liarokapis, Fotis; Anderson, Eike Falk (The Eurographics Association, 2010)
      In this paper we describe the use of a high-level augmented reality (AR) interface for the construction of collabo- rative educational applications that can be used in practice to enhance current teaching methods. A ...

    • Using Cayley Menger Determinants 

      Michelucci, D.; Foufou, S. (The Eurographics Association, 2004)
      We use Cayley-Menger Determinants (CMDs) to obtain an intrinsic formulation of geometric constraints. First, we show that classical CMDs are very convenient to solve the Stewart platform problem. Second, issues like distances ...

    • Using constraints to describe high-level behaviours in virtual worlds 

      Richard, N.; Codognet, P.; Grumbach, A. (Eurographics Association, 1998)
      Our aim is to make the authoring of virtual worlds easier for non-specialists, in particular when programming pseudo-intelligent agents within virtual environments.We are designing a high-level language as well as a library ...

    • Using Data Comics to Enhance Visualization Literacy 

      Boucher, Magdalena; Stoiber, Christina; Aigner, Wolfgang (The Eurographics Association, 2022)
      Visualization Literacy as a skill is becoming important, as growing amounts of data require complex ways of visualizing and interpreting them. Yet, it is hardly taught during general education, and not many resources ...

    • Using ECPs for Interactive Applications in Virtual Cinematography 

      Wu, Hui-Yin; Li, Tsai-Yen; Christie, Marc (The Eurographics Association, 2017)
      This paper introduces an interactive application of our previous work on the Patterns language as creative assistant for editing cameras in 3D virtual environments. Patterns is a set of vocabulary, which was inspired by ...

    • Using Exercise Cycle as a Haptic Input Device in a Virtual Environment 

      Välkkynen, Pasi; Heinilä, Juhani; Lainio, Sari; Lakaniemi, Sami; Väätänen, Antti (The Eurographics Association, 2001)
      Virku (Virtual Fitness Centre) is a study, in which an exercise cycle is used for navigating in a virtual environment. The cycle acts as a haptic bodily user interface between the user and the simulation. The simulation ...

    • Using Flash Photography and Image-Based Rendering to Document Cultural Heritage Artifacts 

      Tetzlaff, Michael; Meyer, Gary (The Eurographics Association, 2016)
      A novel image-based rendering system is proposed for documenting cultural heritage artifacts. The system utilizes backscattering photography to acquire the initial pictures and derives estimates for the object's diffuse ...

    • Using GKS Concurrently: a Practical Solution 

      Flores, J. Zamorano; Costoya, F. Perez; Perez, J. Carretero and Henriquez, L.M. Gomez and Ambite, A. Perez (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      This paper analyses the use of GKS with concurrent languages, showing the inherent problems that arise when working in a multitasking environment. A theoretical solution and its practical implementation are described.

    • Using Graphs for Exposing the Underlying Competence Design of Academic Degrees 

      Blasco-Soplon, Laia; Minguillón, Julià (The Eurographics Association, 2017)
      Academic degrees are usually presented with textual tables and lists, following a semester structure. This information is expected to help learners to create their own itineraries within a given degree, which may not be ...

    • Using Graphs for Fast Error Term Approximation of Time-varying Datasets 

      Nuber, C.; LaMar, E. C.; Pascucci, V.; Hamann, B.; Joy, K. I. (The Eurographics Association, 2003)
      We present a method for the efficient computation and storage of approximations of error tables used for error estimation of a region between different time steps in time-varying datasets. The error between two time steps ...

    • Using Hardware Ray Transforms to Accelerate Ray/Primitive Intersections for Long, Thin Primitive Types 

      Wald, Ingo; Morrical, Nate; Zellmann, Stefan; Ma, Lei; Usher, Will; Huang, Tiejun; Pascucci, Valerio (ACM, 2020)
      With the recent addition of hardware ray tracing capabilities, GPUs have become incredibly efficient at ray tracing both triangular geometry, and instances thereof. However, the bounding volume hierarchies that current ray ...

    • Using Icicle Trees to Encode the Hierarchical Structure of Source Code 

      Bacher, Ivan; Namee, Brian Mac; Kelleher, John D. (The Eurographics Association, 2016)
      This paper presents a study which evaluates the use of a tree visualisation (icicle tree) to encode the hierarchical structure of source code. The tree visualisation was combined with a source code editor in order to ...

    • Using K-Means Clustering for a Spatial Analysis of Multivariate and Time-Varying Microclimate Data 

      Häb, Kathrin; Middel, Ariane; Hagen, Hans (The Eurographics Association, 2013)
      In this study, we propose a k-means clustering algorithm combined with glyph-based encoding method to analyze the spatial distribution and dependence of multivariate, time-varying 3D microclimate data. We obtained five ...
