    • Efficient Propagation of Light Field Edits 

      Jarabo, Adrian; Masia, Belen; Gutierrez, Diego (The Eurographics Association, 2021)
      Light field editing is a complex task, due to the large amount of data and the need to keep consistency between views. This has hampered the creation of efficient edit propagation methods, similar to those existing for ...

    • Efficient Remote Rendering Using Equirectangular Projection 

      McNamee, Josh; Debattista, Kurt; Chalmers, Alan (The Eurographics Association, 2017)
      Presenting high quality Virtual Reality (VR) experiences on head-mounted displays (HMDs) requires significant computational requirements. To ensure a high-fidelity experience, the displayed images must be highly accurate, ...

    • Efficient Representation of Layered Depth Images for Real-time Volumetric Tests 

      Trapp, Matthias; Döllner, Jürgen (The Eurographics Association, 2008)
      Representing Layered Depth Images (LDI) as 3D texture can be used to approximate complex, arbitrarily shaped volumes on graphics hardware. Based on this concept, a number of real-time applications such as collision detection ...

    • An Efficient Restricted Quadtree Triangulation based on the Hilbert Space-filling Curve 

      Valle, Y. (The Eurographics Association, 2008)
      Digital Terrain Models play an important role in a variety of applications such as games, virtual simulations and geographic information systems. Most of terrain visualization techniques are based on multiresolution models ...

    • Efficient use of Multiple Hardware Components for Image Synthesis 

      Pereira, Francisco; Moura, João Paulo; Magalhães, José Afonso Bulas Cruz Luís; Chamers, Alan (The Eurographics Association, 2021)
      With the advent of affordable and powerful computers systems, even in desktop configurations, the rapid render­ing of complex scenes using global illumination algorithms is within reach. However, some significant problems ...

      Santos, Beatriz Sousa; Ferreira, Carlos (The Eurographics Association, 2023)
      Neste trabalho descreve-se resumidamente uma experiência simples que os autores realizaram com o intuito de tentar perceber, por um lado se a utilização de determinados documentos multimedia para apoio ao estudo de matérias ...

    • Elaboração de Conteúdos 3D para utilização na CaveHollowspace do Lousal 

      Ponciano, Luís Miguel S; Dias, Miguel Sales (The Eurographics Association, 2021)
      Este poster descreve as diversas etapas da elaboração de conteúdo 3D para utilização no ambiente de realidade virtual imersivo instalado no Centro de Ciência Viva do Lousal.

    • Email Visualization: A Context-Based Approach 

      Cardoso, Celso; Silva, Paula Alexandra (The Eurographics Association, 2021)
      Email has become a widespread communication medium, but its interface has not undergone many changes over the years. The main contribution of this work is to propose a context-based email visualization application, which ...

    • Emotion Transfer for 3D Hand Motion using StarGAN 

      Chan, Jacky C. P.; Irimia, Ana-Sabina; Ho, Edmond S. L. (The Eurographics Association, 2020)
      In this paper, we propose a new data-driven framework for 3D hand motion emotion transfer. Specifically, we first capture highquality hand motion using VR gloves. The hand motion data is then annotated with the emotion ...
