    • Fast Maximal Poisson-Disk Sampling by Randomized Tiling 

      Wang, Tong; Suda, Reiji (ACM, 2017)
      It is generally accepted that Poisson disk sampling provides great properties in various applications in computer graphics. We present KD-tree based randomized tiling (KDRT), an e cient method to generate maximal Poisson-disk ...

    • A Hardware-Friendly Bilateral Solver Accelerator for Real-Time Virtual Reality Video 

      Mazumdar, Amrita; Alaghi, Armin; Barron, Jonathan T.; Gallup, David; Ceze, Luis; Oskin, Mark; Seitz, Steven M. (ACM, 2017)
      Rendering 3D-360° VR video from a camera rig is computationintensive and typically performed o ine. In this paper, we target the most time-consuming step of the VR video creation process, high-quality ow estimation with ...

    • Hierarchical Multi-Layer Screen-Space Ray Tracing 

      Hofmann, Nikolai; Bogendörfer, Phillip; Stamminger, Marc; Selgrad, Kai (ACM, 2017)
      In this paper we present a method for fast screen-space ray tracing. Single-layer screen-space ray marching is an established tool in high-performance applications, such as games, where plausible and appealing results are ...

    • Improved Two-Level BVHs Using Partial Re-Braiding 

      Benthin, Carsten; Woop, Sven; Afra, Attila T.; Wald, Ingo (ACM, 2017)
      We propose a novel approach for improving the quality of two-level BVHs (i.e., a two-level data structure that uses a top-level BVH built over second-level object BVHs). After building an individual, high-quality BVH for ...

    • Interactive Stable Ray Tracing 

      Corso, Alessandro Dal; Salvi, Marco; Kolb, Craig; Frisvad, Jeppe Revall; Lefohn, Aaron; Luebke, David (ACM, 2017)
      Interactive ray tracing applications running on commodity hard- ware can su er from objectionable temporal artifacts due to a low sample count. We introduce stable ray tracing, a technique that improves temporal stability ...

    • Mesh Color Textures 

      Yuksel, Cem (ACM, 2017)
      The fundamental limitations of texture mapping has been a long standing problem in computer graphics. The cost of defining and maintaining texture coordinates and the seams that introduce various filtering inconsistencies ...

    • Non-Linearly Quantized Moment Shadow Maps 

      Peters, Christoph (ACM, 2017)
      Moment shadow maps enable direct filtering to accomplish proper antialiasing of dynamic hard shadows. For each texel, the moment shadow map stores four powers of the depth in either 64 or 128 bits. After filtering, this ...

    • Spatiotemporal Variance-Guided Filtering: Real-Time Reconstruction for Path Traced Global Illumination 

      Schied, Christoph; Kaplanyan, Anton; Wyman, Chris; Patney, Anjul; Chaitanya, Chakravarty Reddy Alla; Burgess, John; Liu, Shiqiu; Dachsbacher, Carsten; Lefohn, Aaron; Salvi, Marco (ACM, 2017)
      We introduce a reconstruction algorithm that generates a tempo- rally stable sequence of images from one path-per-pixel global illumination. To handle such noisy input, we use temporal accu- mulation to increase the e ...

    • STBVH: A Spatial-Temporal BVH for Efficient Multi-Segment Motion Blur 

      Woop, Sven; Afra, Attila T.; Benthin, Carsten (ACM, 2017)
      We present the STBVH, a newapproach for rendering multi-segment motion blur using a bounding volume hierarchy (BVH) that stores both spatial linearly interpolated bounds and temporal bounds. The approach is designed for ...

    • Timeline Scheduling for Out-of-Core Ray Batching 

      Son, Myungbae; Yoon, Sung- Eui (ACM, 2017)
      We present a timeline based scheduling method for Monte Carlo ray tracing of out-of-core models on distributed memory clusters. We abstract different setups of various compute and memory devices into a graph-based ...

    • Vectorized Production Path Tracing 

      Lee, Mark; Green, Brian; Xie, Feng; Tabellion, Eric (ACM, 2017)
      This paper presents MoonRay, a high performance production rendering architecture using Monte Carlo path tracing developed at DreamWorks Animation. MoonRay is the first production path tracer, to our knowledge, designed ...
