    • Medical Visualization with New Generation Spatial 3D Displays 

      Agus, Marco; Bettio, Fabio; Gobbetti, Enrico; Pintore, Giovanni (The Eurographics Association, 2007)
      In this paper the capabilities of a modern spatial 3D display are exploited for medical visualization tasks. The systemgives multiple viewers the illusion of seeing virtual objects floating at fixed physical locations. The ...
    • Medidas e Deteção de Estruturas Morfológicas para Craniometria usando Modelos 3D 

      Neves, Luís; Dias, Paulo; Coelho, Catarina; Ferreira, Maria Teresa; Santos, Hélder; Santos, Beatriz Sousa (The Eurographics Association, 2020)
      Este artigo descreve os recentes desenvolvimentos num trabalho ainda em curso referente a uma nova abordagem à craniometria tradicional baseada na análise de modelos digitais 3D de crânios através da aplicação CraMs ...
    • Melhorando o Ensino Universitário com a Gamificação 

      Barata, Gabriel; Gama, Sandra; Jorge, Joaquim; Gonçalves, Daniel (The Eurographics Association, 2020)
      A gamificação é uma técnica recente que consiste em aplicar elementos de jogos a contextos não relacionados com jogos, por forma a motivar os utilizadores a adoptar novos comportamentos, tais como fazer mais exercício, ou ...
    • Memory Efficient Surface Reconstruction Based on Self Organising Maps 

      Kaye, David Paul; Ivrissimtzis, Ioannis (The Eurographics Association, 2011)
      We propose a memory efficient, scalable surface reconstruction algorithm based on self organising maps (SOMs). Following previous approaches to SOM based implicit surface reconstruction, the proposed SOM has the geometry ...
    • Memory Leak Analysis using Time-Travel-based and Timeline-based Tree Evolution Visualizations 

      Weninger, Markus; Makor, Lukas; Mössenböck, Hanspeter (The Eurographics Association, 2020)
      Memory leaks occur when no longer needed objects are unnecessarily kept alive. They can have a significant negative performance impact, leading to a crash in the worst case. Thus, tool support for heap evolution analysis, ...
    • A Mesh Correspondence Approach for Efficient Animation Transfer 

      Moutafidou, Anastasia; Fudos, Ioannis (The Eurographics Association, 2019)
      Animating a novel character not only needs a lot of effort and time but also requires the intervention of an experienced user. Moreover, the traditional animation pipeline for a set of characters can be a tedious and ...
    • A Mesh Generation Perspective on Robust Mappings 

      Livesu, Marco (The Eurographics Association, 2020)
      Mapping a shape to some parametric domain is a fundamental tool in graphics and scientific computing. In practice, a map between two shapes is commonly represented by two meshes with same connectivity and different embedding. ...
