      Understanding how software entities in a repository evolve over time is challenging, as an entity has many aspects that undergo such changes. We cast this problem in a multidimensional visualization context: First, we ...

    • A Metric for Computing Adaptive Detail in Animated Scenes Using Object-Oriented Programming 

      Blake, Edwin H. (Eurographics Association, 1987)
      A spatial metric for adapting the level of detail in a modelled object to achieve a convincing degree of realism on a display is formulated and illustrated with a simple implementation. This spatial metric is designed to ...

      Li, Wei; Elderman, Joep; Hoogerwoord, Erwin; Funk, Mathias; Brombacher, Aarnout C. (The Eurographics Association, 2016)
      Healthcare data is the emerging force to push ahead smarter clinical solutions. However, unforeseen challenges like unmanaged massive data and costly access to it make it difficult for domain experts to easily derive ...

    • Metro Maps on Octilinear Grid Graphs 

      Bast, Hannah; Brosi, Patrick; Storandt, Sabine (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Schematic transit maps (often called "metro maps" in the literature) are important to produce comprehensible visualizations of complex public transit networks. In this work, we investigate the problem of automatically ...

    • Metro Transit-Centric Visualization for City Tour Planning 

      Claudio, Pio; Yoon, Sung-Eui (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In general, city trip planning consists of two main steps: knowing Points-Of-Interest (POIs), and then planning a tour route from the current point to next preferred POIs. We mainly consider the metro for traveling around ...

    • Metro: Measuring Error on Simplified Surfaces 

      Cignoni, P.; Rocchini, C.; Scopigno, R. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This paper presents a new tool, Metro, designed to compensate for a deficiency in many simplification methods proposed in literature. Metro allows one to compare the difference between a pair of surfaces (e.g. a triangulated ...

    • Metropolis Instant Radiosity 

      Segovia, B.; Iehl, J.C.; Peroche, B. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present Metropolis Instant Radiosity (MIR), an unbiased algorithm to solve the Light Transport problem. MIR is a hybrid technique which consists in representing the incoming radiance field by a set of Virtual Point ...
