    • Conservative Ray Batching using Geometry Proxies 

      Molenaar, Mathijs; Eisemann, Elmar (The Eurographics Association, 2020)
      We present a method for improving batched ray traversal as was presented by Pharr et al. [PKGH97]. We propose to use conservative proxy geometry to more accurately determine whether a ray has a possibility of hitting any ...
    • Directed Acyclic Graph Encoding for Compressed Shadow Maps 

      Scandolo, Leonardo; Eisemann, Elmar (The Eurographics Association, 2021)
      Detailed shadows in large-scale environments are challenging. Our approach enables efficient detailed shadow computations for static environments at a low memory cost. It builds upon compressed precomputed multiresolution ...
    • Gradient‐Guided Local Disparity Editing 

      Scandolo, Leonardo; Bauszat, Pablo; Eisemann, Elmar (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Stereoscopic 3D technology gives visual content creators a new dimension of design when creating images and movies. While useful for conveying emotion, laying emphasis on certain parts of the scene, or guiding the viewer's ...
    • MegaViews: Scalable Many‐View Rendering With Concurrent Scene‐View Hierarchy Traversal 

      Kol, Timothy R.; Bauszat, Pablo; Lee, Sungkil; Eisemann, Elmar (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present a scalable solution to render complex scenes from a large amount of viewpoints. While previous approaches rely either on a scene or a view hierarchy to process multiple elements together, we make full use of ...
    • Model-based Visualization for Medical Education and Training 

      Smit, Noeska; Lawonn, Kai; Kraima, Annelot; deRuiter, Marco; Bruckner, Stefan; Eisemann, Elmar; Vilanova, Anna (The Eurographics Association, 2019)
      Anatomy, or the study of the structure of the human body, is an essential component of medical education. Certain parts of human anatomy are considered to be more complex to understand than others, due to a multitude of ...
    • A New Baseline for Feature Description on Multimodal Imaging of Paintings 

      Toorn, Jules van der; Wiersma, Ruben; Vandivere, Abbie; Marroquim, Ricardo; Eisemann, Elmar (The Eurographics Association, 2022)
      Multimodal imaging is used by conservators and scientists to study the composition of paintings. To aid the combined analysis of these digitisations, such images must first be aligned. Rather than proposing a new domain-specific ...
    • Semi-Automatic Perspective Lines from Paintings 

      Coudert-Osmont, Yoann; Eisemann, Elmar; Marroquim, Ricardo (The Eurographics Association, 2022)
      Perspective cues play an important role in painting analysis as it may unveil important characteristics about the painter's techniques and creation process. Nevertheless, extracting perspective lines and their corresponding ...
    • Spectral Processing of Tangential Vector Fields 

      Brandt, Christopher; Scandolo, Leonardo; Eisemann, Elmar; Hildebrandt, Klaus (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose a framework for the spectral processing of tangential vector fields on surfaces. The basis is a Fourier‐type representation of tangential vector fields that associates frequencies with tangential vector fields. ...
    • A Survey on Gradient-Domain Rendering 

      Hua, Binh-Son; Gruson, Adrien; Petitjean, Victor; Zwicker, Matthias; Nowrouzezahrai, Derek; Eisemann, Elmar; Hachisuka, Toshiya (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Monte Carlo methods for physically-based light transport simulation are broadly adopted in the feature film production, animation and visual effects industries. These methods, however, often result in noisy images and have ...
    • Visual Analysis of RIS Data for Endmember Selection 

      Popa, Andra; Gabrieli, Francesca; Kroes, Thomas; Krekeler, Anna; Alfeld, Matthias; Lelieveldt, Boudewijn; Eisemann, Elmar; Höllt, Thomas (The Eurographics Association, 2022)
      Reflectance Imaging Spectroscopy (RIS) is a hyperspectral imaging technique used for investigating the molecular composition of materials. It can help identify pigments used in a painting, which are relevant information ...
