    • Cytosplore: Interactive Visual Single-Cell Profiling of the Immune System 

      Höllt, Thomas; Pezzotti, Nicola; van Unen, Vincent; Li, Na; Koning, Frits; Eisemann, Elmar; Lelieveldt, Boudewijn P. F.; Vilanova, Anna (The Eurographics Association, 2019)
      Recent advances in single-cell acquisition technology have led to a shift towards single-cell analysis in many fields of biology. In immunology, detailed knowledge of the cellular composition is of interest, as it can be ...

    • Editing Compressed High-resolution Voxel Scenes with Attributes 

      Molenaar, Mathijs; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Sparse Voxel Directed Acyclic Graphs (SVDAGs) are an efficient solution for storing high-resolution voxel geometry. Recently, algorithms for the interactive modification of SVDAGs have been proposed that maintain the ...

    • Geometric Sample Reweighting for Monte Carlo Integration 

      Guo, Jerry Jinfeng; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Numerical integration is fundamental in multiple Monte Carlo rendering problems. We present a sample reweighting scheme, including underlying theory, and analysis of numerical performance for the integration of an unknown ...

    • Interactive Depixelization of Pixel Art through Spring Simulation 

      Matusovic, Marko; Parakkat, Amal Dev; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      We introduce an approach for converting pixel art into high-quality vector images. While much progress has been made on automatic conversion, there is an inherent ambiguity in pixel art, which can lead to a mismatch with ...

    • A Multi-pass Method for Accelerated Spectral Sampling 

      Ruit, Mark van de; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Spectral Monte Carlo rendering can simulate advanced light phenomena, such as chromatic dispersion, but typically shows a slow convergence behavior. Properly sampling the spectral domain can be challenging in scenes with ...

    • Pacific Graphics 2021 - CGF 40-7: Frontmatter 

      Zhang, Fang-Lue; Eisemann, Elmar; Singh, Karan (The Eurographics Association and John Wiley & Sons Ltd., 2021)

    • 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 ...

    • ShutterApp: Spatio-temporal Exposure Control for Videos 

      Salamon, Nestor; Billeter, Markus; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      A camera's shutter controls the incoming light that is reaching the camera sensor. Different shutters lead to wildly different results, and are often used as a tool in movies for artistic purpose, e.g., they can indirectly ...
