    • Fast Polygonal Splatting using Directional Kernel Difference 

      Moroto, Yuji; Hachisuka, Toshiya; Umetani, Nobuyuki (The Eurographics Association, 2021)
      Depth-of-field (DoF) filtering is an important image-processing task for producing blurred images similar to those obtained with a large aperture camera lens. DoF filtering applies an image convolution with a spatially ...
    • Scalable Virtual Ray Lights Rendering for Participating Media 

      Vibert, Nicolas; Gruson, Adrien; Stokholm, Heine; Mortensen, Troels; Jarosz, Wojciech; Hachisuka, Toshiya; Nowrouzezahrai, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Virtual ray lights (VRL) are a powerful representation for multiple-scattered light transport in volumetric participating media. While efficient Monte Carlo estimators can importance sample the contribution of a VRL along ...
    • Single-pass Stratified Importance Resampling 

      Ciklabakkal, Ege; Gruson, Adrien; Georgiev, Iliyan; Nowrouzezahrai, Derek; Hachisuka, Toshiya (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Resampling is the process of selecting from a set of candidate samples to achieve a distribution (approximately) proportional to a desired target. Recent work has revisited its application to Monte Carlo integration, ...
    • Stratified Markov Chain Monte Carlo Light Transport 

      Gruson, Adrien; West, Rex; Hachisuka, Toshiya (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Markov chain Monte Carlo (MCMC) sampling is a powerful approach to generate samples from an arbitrary distribution. The application to light transport simulation allows us to efficiently handle complex light transport such ...
    • Surface-Only Dynamic Deformables using a Boundary Element Method 

      Sugimoto, Ryusuke; Batty, Christopher; Hachisuka, Toshiya (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We propose a novel surface-only method for simulating dynamic deformables without the need for volumetric meshing or volumetric integral evaluations. While based upon a boundary element method (BEM) for linear elastodynamics, ...
    • 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 ...
