      The Fluid Implicit Particle method (FLIP) for liquid simulations uses particles to reduce numerical dissipation and provide important visual cues for events like complex splashes and small-scale features near the liquid ...
    • Near-Instant Capture of High-Resolution Facial Geometry and Reflectance 

      Fyffe, Graham; Graham, Paul; Tunwattanapong, Borom; Ghosh, Abhijeet; Debevec, Paul (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a near-instant method for acquiring facial geometry and reflectance using a set of commodity DSLR cameras and flashes. Our setup consists of twenty-four cameras and six flashes which are fired in rapid succession ...
    • An Objective Deghosting Quality Metric for HDR Images 

      Tursun, Okan Tarhan; Akyüz, Ahmet Oğuz; Erdem, Aykut; Erdem, Erkut (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Reconstructing high dynamic range (HDR) images of a complex scene involving moving objects and dynamic backgrounds is prone to artifacts. A large number of methods have been proposed that attempt to alleviate these artifacts, ...
    • A Practical and Controllable Hair and Fur Model for Production Path Tracing 

      Chiang, Matt Jen-Yuan; Bitterli, Benedikt; Tappan, Chuck; Burley, Brent (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present an energy-conserving fiber shading model for hair and fur that is efficient enough for path tracing. Our model adopts a near-field formulation to avoid the expensive integral across the fiber, accounts for all ...
    • A Practical Method for High-Resolution Embedded Liquid Surfaces 

      Goldade, Ryan; Batty, Christopher; Wojtan, Chris (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Combining high-resolution level set surface tracking with lower resolution physics is an inexpensive method for achieving highly detailed liquid animations. Unfortunately, the inherent resolution mismatch introduces several ...
    • Regularizing Image Reconstruction for Gradient-Domain Rendering with Feature Patches 

      Manzi, Marco; Vicini, Delio; Zwicker, Matthias (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel algorithm to reconstruct high-quality images from sampled pixels and gradients in gradient-domain rendering. Our approach extends screened Poisson reconstruction by adding additional regularization ...
    • SAH Guided Spatial Split Partitioning for Fast BVH Construction 

      Ganestam, Per; Doggett, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a new SAH guided approach to subdividing triangles as the scene is coarsely partitioned into smaller sets of spatially coherent triangles. Our triangle split approach is integrated into the partitioning stage ...
    • Seamless Video Stitching from Hand-held Camera Inputs 

      Lin, Kaimo; Liu, Shuaicheng; Cheong, Loong-Fah; Zeng, Bing (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Images/videos captured by portable devices (e.g., cellphones, DV cameras) often have limited fields of view. Image stitching, also referred to as mosaics or panorama, can produce a wide angle image by compositing several ...
    • Single Image Weathering via Exemplar Propagation
