    • Accessible Digitisation and Visualisation of Open Cultural Heritage Assets 

      Medeiros e Sá, Asla; Ibañez Vila, Adolfo Bartolome; Rodriguez Echavarria, Karina; Marroquim, Ricardo; Luiz Fonseca, Vivian (The Eurographics Association, 2019)
      In this research, we proposed a methodology for documenting open and medium-large scale cultural heritage assets. By open we mean both in the sense of their location in open spaces and the fact that they are openly accessible ...
    • A Practical and Efficient Approach for Correct Z-Pass Stencil Shadow Volumes 

      Usta, Baran; Scandolo, Leonardo; Billeter, Markus; Marroquim, Ricardo; Eisemann, Elmar (The Eurographics Association, 2019)
      Shadow volumes are a popular technique to compute pixel-accurate hard shadows in 3D scenes. Many variants exist that trade off accuracy and efficiency. In this work, we present an artifact-free, efficient, and easy-to-implement ...
    • What is the Reddening Effect and does it really exist? 

      Clausen, Olaf; Marroquim, Ricardo; Fuhrmann, Arnulph; Weigand, Holger (The Eurographics Association, 2019)
      The simulation of light-matter interaction is a major challenge in computer graphics. Particularly challenging is the modelling of light-matter interaction of rough surfaces, which contain several different scales of ...
