    • Screen Space Approximate Gaussian Hulls 

      Meder, Julian; Brüderlin, Beat (The Eurographics Association, 2018)
      The Screen Space Approximate Gaussian Hull method presented in this paper is based on an output sensitive, adaptive approach, which addresses the challenge of high quality rendering even for high resolution displays and ...
    • Soft Transparency for Point Cloud Rendering 

      Seemann, Patrick; Palma, Gianpaolo; Dellepiane, Matteo; Cignoni, Paolo; Goesele, Michael (The Eurographics Association, 2018)
      We propose a novel rendering framework for visualizing point data with complex structures and/or different quality of data. The point cloud can be characterized by setting a per-point scalar field associated to the aspect ...
    • Scalable Real-Time Shadows using Clustering and Metric Trees 

      Deves, François; Mora, Frédéric; Aveneau, Lilian; Ghazanfarpour, Djamchid (The Eurographics Association, 2018)
      Real-time shadow algorithms based on geometry generally produce high quality shadows. Recent works have considerably improved their efficiency. However, scalability remains an issue because these methods strongly depend ...
    • Primary Sample Space Path Guiding 

      Guo, Jerry Jinfeng; Bauszat, Pablo; Bikker, Jacco; Eisemann, Elmar (The Eurographics Association, 2018)
      Guiding path tracing in light transport simulation has been one of the practical choices for variance reduction in production rendering. For this purpose, typically structures in the spatial-directional domain are built. ...
    • An Improved Multiple Importance Sampling Heuristic for Density Estimates in Light Transport Simulations 

      Jendersie, Johannes; Grosch, Thorsten (The Eurographics Association, 2018)
      Vertex connection and merging (VCM) is one of the most robust light transport simulation algorithms developed so far. It combines bidirectional path tracing with photon mapping using multiple importance sampling (MIS). ...
    • Deep Hybrid Real and Synthetic Training for Intrinsic Decomposition 

      Bi, Sai; Kalantari, Nima Khademi; Ramamoorthi, Ravi (The Eurographics Association, 2018)
      Intrinsic image decomposition is the process of separating the reflectance and shading layers of an image, which is a challenging and underdetermined problem. In this paper, we propose to systematically address this problem ...
    • A Unified Manifold Framework for Efficient BRDF Sampling based on Parametric Mixture Models 

      Herholz, Sebastian; Elek, Oskar; Schindel, Jens; Křivánek, Jaroslav; Lensch, Hendrik P. A. (The Eurographics Association, 2018)
      Virtually all existing analytic BRDF models are built from multiple functional components (e.g., Fresnel term, normal distribution function, etc.). This makes accurate importance sampling of the full model challenging, and ...
    • PN-Method for Multiple Scattering in Participating Media 

      Koerner, David; Portsmouth, Jamie; Jakob, Wenzel (The Eurographics Association, 2018)
      Rendering highly scattering participating media using brute force path tracing is a challenge. The diffusion approximation reduces the problem to solving a simple linear partial differential equation. Flux-limited diffusion ...
    • Matrix Bidirectional Path Tracing 

      Chaitanya, Chakravarty Reddy Alla; Belcour, Laurent; Hachisuka, Toshiya; Premoze, Simon; Pantaleoni, Jacopo; Nowrouzezahrai, Derek (The Eurographics Association, 2018)
      Sampled paths in Monte Carlo ray tracing can be arbitrarily close to each other due to its stochastic nature. Such clumped samples in the path space tend to contribute little toward an accurate estimate of each pixel. ...
    • Approximate svBRDF Estimation From Mobile Phone Video 

      Albert, Rachel A.; Chan, Dorian Yao; Goldman, Dan B.; O'Brien, James F. (The Eurographics Association, 2018)
      We describe a new technique for obtaining a spatially varying BRDF (svBRDF) of a flat object using printed fiducial markers and a cell phone capable of continuous flash video. Our homography-based video frame alignment ...
    • Diffuse-Specular Separation using Binary Spherical Gradient Illumination 

      Kampouris, Christos; Zafeiriou, Stefanos; Ghosh, Abhijeet (The Eurographics Association, 2018)
      We introduce a novel method for view-independent diffuse-specular separation of albedo and photometric normals without requiring polarization using binary spherical gradient illumination. The key idea is that with binary ...
    • Eurographics Symposium on Rendering - Experimental Ideas and Implementations: Frontmatter 

      Jakob, Wenzel; Hachisuka, Toshiya (The Eurographics Association, 2018)
    • What if we use the "What if" Approach for Eco-Feedback? Designing an Electricity Consumption Analysis for Layman Users 

      Wambecke, Jérémy; Bonneau, Georges-Pierre; Blanch, Renaud; Vergne, Romain (The Eurographics Association, 2018)
      Many households share the objective of reducing electricity consumption for either economic or ecological motivations. Ecofeedback technologies support this objective by providing users with a visualization of their ...
    • Visualizing Electrical Power Systems as Flow Fields 

      Molnar, Samantha; Gruchalla, Kenny (The Eurographics Association, 2018)
      We describe a method for visualizing data flows on large networks. We transform data flow on fixed networks into a vector field, which can be directly visualized using scientific flow visualization techniques. We evaluated ...
    • Visual Analysis of Urban Traffic Data based on High-Resolution and High-Dimensional Environmental Sensor Data 

      Häußler, Johannes; Stein, Manuel; Seebacher, Daniel; Janetzko, Halldor; Schreck, Tobias; Keim, Daniel (The Eurographics Association, 2018)
      Urbanization is an increasing global trend resulting in a strong increase in public and individual transportation needs. Accordingly, a major challenge for traffic and urban planners is the design of sustainable mobility ...
    • TreeeX: Exploring the Diversity of Tree Species 

      Jänicke, Stefan (The Eurographics Association, 2018)
      The GlobalTreeSearch database provides a mapping between 60,065 tree species known to science and the countries where these trees grow. TreeeX is a visual exploration system that supports multifaceted analyses of the ...
    • How To Look at Data: Environmental Practitioners' Lens Through Two Case Studies 

      Ling, Meng; Johnson, Jeffrey A.; Feng, Zhiquan; Chen, Jian (The Eurographics Association, 2018)
      Exploratory data visualization, an idea proposed by Tukey in 1977, is meant to output various types of visualization in order to make the data more understandable. While visualization researchers have generated many novel ...
