    • An Interactive Perceptual Rendering Pipeline using Contrast and Spatial Masking 

      Drettakis, George; Bonneel, Nicolas; Dachsbacher, Carsten; Lefebvre, Sylvain; Schwarz, Michael; Viaud-Delmon, Isabelle (The Eurographics Association, 2007)
      We present a new perceptual rendering pipeline which takes into account visual masking due to contrast and spatial frequency. Our framework predicts inter-object, scene-level masking caused by partial occlusion and shadows. ...

    • Soft Shadows by Ray Tracing Multilayer Transparent Shadow Maps 

      Xie, Feng; Tabellion, Eric; Pearce, Andrew (The Eurographics Association, 2007)
      We present a method for high quality soft shadows for area lights in cinematic lighting. The method is an extension of traditional shadow maps, so it has the advantage of image based shadow methods; the algorithm s complexity ...

    • Physically Based Real-Time Translucency for Leaves 

      Habel, Ralf; Kusternig, Alexander; Wimmer, Michael (The Eurographics Association, 2007)
      This paper presents a new shading model for real-time rendering of plant leaves that reproduces all important attributes of a leaf and allows for a large number of leaves to be shaded. In particular, we use a physically ...

    • Rendering Translucent Materials Using Photon Diffusion 

      Donner, Craig; Jensen, Henrik Wann (The Eurographics Association, 2007)
      We present a new algorithm for rendering translucent materials that combines photon tracing with diffusion. This combination makes it possible to efficiently render highly scattering translucent materials while accounting ...

    • Procedural Editing of Bidirectional Texture Functions 

      Mueller, Gero; Sarlette, Ralf; Klein, Reinhard (The Eurographics Association, 2007)
      Measured material representations like Bidirectional Texture Functions or Reflectance Fields offer very realistic appearance but the user is currently not capable of changing this appearance in an effective and intuitive ...

    • Rendering Discrete Random Media Using Precomputed Scattering Solutions 

      Moon, Jonathan T.; Walter, Bruce; Marschner, Stephen R. (The Eurographics Association, 2007)
      This paper addresses light transport through a discrete random medium, which we define as a volume filled with macroscopic scattering geometry generated by a random process. This formulation is more general than standard ...

    • Efficient Basis Decomposition for Scattered Reflectance Data 

      Weistroffer, R. Peter; Walcott, Kristen R.; Humphreys, Greg; Lawrence, Jason (The Eurographics Association, 2007)
      Recent progress in acquisition technology has increased the availability and quality of measured appearance data. Although representations based on dimensionality reduction provide the greatest fidelity to measured data, ...

    • Rapid Acquisition of Specular and Diffuse Normal Maps from Polarized Spherical Gradient Illumination 

      Ma, Wan-Chun; Hawkins, Tim; Peers, Pieter; Chabert, Charles-Felix; Weiss, Malte; Debevec, Paul (The Eurographics Association, 2007)
      We estimate surface normal maps of an object from either its diffuse or specular reflectance using four spherical gradient illumination patterns. In contrast to traditional photometric stereo, the spherical patterns allow ...

    • Microfacet Models for Refraction through Rough Surfaces 

      Walter, Bruce; Marschner, Stephen R.; Li, Hongsong; Torrance, Kenneth E. (The Eurographics Association, 2007)
      Microfacet models have proven very successful for modeling light reflection from rough surfaces. In this paper we review microfacet theory and demonstrate how it can be extended to simulate transmission through rough ...

    • Material Based Splashing of Water Drops 

      Garg, Kshitiz; Krishnan, Gurunandan G.; Nayar, Shree K. (The Eurographics Association, 2007)
      The splashing of a water drop is a fascinating phenomenon that results from a variety of complex interactions between the drop and the material it impacts. In general, the distribution of droplets of a splash depends on ...

    • Dirty Glass: Rendering Contamination on Transparent Surfaces 

      Gu, Jinwei; Ramamoorthi, Ravi; Belhumeur, Peter; Nayar, Shree (The Eurographics Association, 2007)
      Rendering of clean transparent objects has been well studied in computer graphics. However, real-world transparent objects are seldom clean their surfaces have a variety of contaminants such as dust, dirt, and lipids. These ...

    • Dynamic Point Distribution for Stroke-based Rendering
