    • Planetary Shadow-Aware Distance Sampling 

      Breyer, Carl; Zirr, Tobias (The Eurographics Association, 2022)
      Dusk and dawn scenes have been difficult for brute force path tracers to handle. We identify that a major source of the inefficiency in explicitly path tracing the atmosphere in such conditions stems from wasting samples ...

    • Polarization-imaging Surface Reflectometry using Near-field Display 

      Nogue, Emilie; Lin, Yiming; Ghosh, Abhijeet (The Eurographics Association, 2022)
      We present a practical method for measurement of spatially varying isotropic surface reflectance of planar samples using a combination of single-view polarization imaging and near-field display illumination. Unlike previous ...

    • Precomputed Discrete Visibility Fields for Real-Time Ray-Traced Environment Lighting 

      Xu, Yang; Jiang, Yuanfa; Wang, Chenhao; Li, Kang; Zhou, Pengbo; Geng, Guohua (The Eurographics Association, 2022)
      Rendering environment lighting using ray tracing is challenging because many rays within the hemisphere are required to be traced. In this work, we propose discrete visibility fields (DVFs), which store visibility information ...

    • A Real-Time Adaptive Ray Marching Method for Particle-Based Fluid Surface Reconstruction 

      Wu, Tong; Zhou, Zhiqiang; Wang, Anlan; Gong, Yuning; Zhang, Yanci (The Eurographics Association, 2022)
      In the rendering of particle-based fluids, the surfaces reconstructed by ray marching techniques contain more details than screen space filtering methods. However, the ray marching process is quite time-consuming because ...

    • Rendering 2022 Symposium Track: Frontmatter 

      Ghosh, Abhijeet; Wei, Li-Yi (The Eurographics Association, 2022)

    • SkyGAN: Towards Realistic Cloud Imagery for Image Based Lighting 

      Mirbauer, Martin; Rittig, Tobias; Iser, Tomáš; Krivánek, Jaroslav; Šikudová, Elena (The Eurographics Association, 2022)
      Achieving photorealism when rendering virtual scenes in movies or architecture visualizations often depends on providing a realistic illumination and background. Typically, spherical environment maps serve both as a natural ...

    • Spatiotemporal Blue Noise Masks 

      Wolfe, Alan; Morrical, Nathan; Akenine-Möller, Tomas; Ramamoorthi, Ravi (The Eurographics Association, 2022)
      Blue noise error patterns are well suited to human perception, and when applied to stochastic rendering techniques, blue noise masks can minimize unwanted low-frequency noise in the final image. Current methods of applying ...

    • Spectral Upsampling Approaches for RGB Illumination 

      Guarnera, Giuseppe Claudio; Gitlina, Yuliya; Deschaintre, Valentin; Ghosh, Abhijeet (The Eurographics Association, 2022)
      We present two practical approaches for high fidelity spectral upsampling of previously recorded RGB illumination in the form of an image-based representation such as an RGB light probe. Unlike previous approaches that ...

    • Stenciled Volumetric Ambient Occlusion 

      Brüll, Felix; Kern, René; Grosch, Thorsten (The Eurographics Association, 2022)
      Screen-space Ambient Occlusion (AO) is commonly used in games to calculate the exposure of each pixel to ambient lighting with the help of a depth buffer. Due to its screen-space nature, it suffers from several artifacts ...
