    • A Novel Method for Fast and High-Quality Rendering of Hair 

      Xu, Songhua; Lau, Francis C. M.; Jiang, Hao; Pan, Yunhe (The Eurographics Association, 2006)
      This paper proposes a new rendering approach for hair. The model we use incorporates semantics-related information directly in the appearance modeling function which we call a Semantics-Aware Texture Function (SATF). This ...
    • Relighting Human Locomotion with Flowed Reflectance Fields 

      Einarsson, Per; Chabert, Charles-Felix; Jones, Andrew; Ma, Wan-Chun; Lamond, Bruce; Hawkins, Tim; Bolas, Mark; Sylwan, Sebastian; Debevec, Paul (The Eurographics Association, 2006)
      We present an image-based approach for capturing the appearance of a walking or running person so they can be rendered realistically under variable viewpoint and illumination. In our approach, a person walks on a treadmill ...
    • Silhouette Texture 

      Wu, Hongzhi; Wei, Li-Yi; Wang, Xi; Guo, Baining (The Eurographics Association, 2006)
      Using coarse meshes with textures and/or normal maps to represent detailed meshes often results in poor visual quality along silhouettes. To tackle this problem, we introduce silhouette texture, a new data structure for ...
    • Texture Transfer Using Geometry Correlation 

      Mertens, Tom; Kautz, Jan; Chen, Jiawen; Bekaert, Philippe; Durand, Frédo (The Eurographics Association, 2006)
      Texture variation on real-world objects often correlates with underlying geometric characteristics and creates a visually rich appearance. We present a technique to transfer such geometry-dependent texture variation from ...
    • Exploiting Temporal Coherence for Incremental All-Frequency Relighting 

      Overbeck, Ryan; Ben-Artzi, Aner; Ramamoorthi, Ravi; Grinspun, Eitan (The Eurographics Association, 2006)
      Precomputed radiance transfer (PRT) enables all-frequency relighting with complex illumination, materials and shadows. To achieve real-time performance, PRT exploits angular coherence in the illumination, and spatial ...
    • Spatio-Angular Resolution Tradeoffs in Integral Photography 

      Georgeiv, Todor; Zheng, Ke Colin; Curless, Brian; Salesin, David; Nayar, Shree; Intwala, Chintan (The Eurographics Association, 2006)
      An integral camera samples the 4D light field of a scene within a single photograph. This paper explores the fundamental tradeoff between spatial resolution and angular resolution that is inherent to integral photography. ...
    • Automatic Multiperspective Images 

      Román, Augusto; Lensch, Hendrik P. A. (The Eurographics Association, 2006)
      Multiperspective images generated from a collection of photographs or a videostream can be used to effectively summarize long, roughly planar scenes such as city streets. The final image will span a larger field of view ...
    • An Efficient Multi-View Rasterization Architecture 

      Hasselgren, Jon; Akenine-Möller, Tomas (The Eurographics Association, 2006)
      TV have been designed and built. However, these displays have received relatively little attention in the context of real-time computer graphics. We present a novel rasterization architecture that rasterizes each triangle ...
    • Real-time Soft Shadow Mapping by Backprojection 

      Guennebaud, Gaël; Barthe, Loïc; Paulin, Mathias (The Eurographics Association, 2006)
      We present a new real-time soft shadow algorithm using a single shadow map per light source. Therefore, our algorithm is well suited to render both complex and dynamic scenes, and it handles all rasterizable geometries. ...
    • Sparse Lumigraph Relighting by Illumination and Reflectance Estimation from Multi-View Images 

      Yu, Tianli; Wang, Hongcheng; Ahuja, Narendra; Chen, Wei-Chao (The Eurographics Association, 2006)
      We present a novel relighting approach that does not assume that the illumination is known or controllable. Instead, we estimate the illumination and texture from given multi-view images captured under a single illumination ...
    • Practical, Real-time Studio Matting using Dual Imagers 

      McGuire, Morgan; Matusik, Wojciech; Yerazunis, William (The Eurographics Association, 2006)
      This paper presents a practical system for capturing high-resolution video mattes using cameras that contain two imagers on one optical axis. The dual imagers capture registered frames that differ only by defocus or ...
    • Statistical Acquisition of Texture Appearance 

      Ngan, Addy; Durand, Frédo (The Eurographics Association, 2006)
      We propose a simple method to acquire and reconstruct material appearance with sparsely sampled data. Our technique renders elaborate view- and light-dependent effects and faithfully reproduces materials such as fabrics ...
    • Surface Enhancement Using Real-time Photometric Stereo and Reflectance Transformation 

      Malzbender, Tom; Wilburn, Bennett; Gelb, Dan; Ambrisco, Bill (The Eurographics Association, 2006)
      Photometric stereo recovers per-pixel estimates of surface orientation from images of a surface under varying lighting conditions. Transforming reflectance based on recovered normal directions is useful for enhancing the ...
    • Painting With Texture 

      Ritter, Lincoln; Li, Wilmot; Curless, Brian; Agrawala, Maneesh; Salesin, David (The Eurographics Association, 2006)
      We present an interactive texture painting system that allows the user to author digital images by painting with a palette of input textures. At the core of our system is an interactive texture synthesis algorithm that ...
    • Adaptive Visibility-Driven View Cell Construction 

      Mattausch, Oliver; Bittner, Jirí; Wimmer, Michael (The Eurographics Association, 2006)
      We present a new method for the automatic partitioning of view space into a multi-level view cell hierarchy. We use a cost-based model in order to minimize the average rendering time. Unlike previous methods, our model ...
    • Ardeco: Automatic Region DEtection and COnversion 

      Lecot, Gregory; Levy, Bruno (The Eurographics Association, 2006)
      We present Ardeco, a new algorithm for image abstraction and conversion from bitmap images into vector graphics. Given a bitmap image, our algorithm automatically computes the set of vector primitives and gradients that ...
    • A Spectral BSSRDF for Shading Human Skin 

      Donner, Craig; Jensen, Henrik Wann (The Eurographics Association, 2006)
      We present a novel spectral shading model for human skin. Our model accounts for both subsurface and surface scattering, and uses only four parameters to simulate the interaction of light with human skin. The four parameters ...
    • Two Stage Importance Sampling for Direct Lighting 

      Cline, David; Egbert, Parris K.; Talbot, Justin F.; Cardon, David L. (The Eurographics Association, 2006)
      We describe an importance sampling method to generate samples based on the product of a BRDF and an environment map or large light source. The method works by creating a hierarchical partition of the light source based on ...
    • Instant Ray Tracing: The Bounding Interval Hierarchy 

      Wächter, Carsten; Keller, Alexander (The Eurographics Association, 2006)
      We introduce a new ray tracing algorithm that exploits the best of previous methods: Similar to bounding volume hierarchies the memory of the acceleration data structure is linear in the number of objects to be ray traced ...
