    • A Space-Efficient Method for Navigable Ensemble Analysis and Visualization 

      Hota, Alok; Raji, Mohammad; Hobson, Tanner; Huang, Jian (The Eurographics Association, 2017)
      Scientists increasingly rely on simulation runs of complex models in lieu of cost-prohibitive or infeasible experimentation. The data output of many controlled simulation runs, the ensemble, is used to verify correctness ...
    • Photo-Guided Exploration of Volume Data Features 

      Raji, Mohammad; Hota, Alok; Sisneros, Robert; Messmer, Peter; Huang, Jian (The Eurographics Association, 2017)
      In this work, we pose the question of whether, by considering qualitative information such as a sample target image as input, one can produce a rendered image of scientific data that is similar to the target. The algorithm ...
    • Progressive CPU Volume Rendering with Sample Accumulation 

      Usher, Will; Amstutz, Jefferson; Brownlee, Carson; Knoll, Aaron; Wald, Ingo (The Eurographics Association, 2017)
      We present a new method for progressive volume rendering by accumulating object-space samples over successively rendered frames. Existing methods for progressive refinement either use image space methods or average pixels ...

      We present our data-driven, neural network-based approach to predicting the performance of a distributed GPU volume renderer for supporting cluster equipment acquisition. On the basis of timing measurements from a single ...
    • PaViz: A Power-Adaptive Framework for Optimizing Visualization Performance 

      Labasan, Stephanie; Larsen, Matthew; Childs, Hank; Rountree, Barry (The Eurographics Association, 2017)
      Power consumption is widely regarded as one of the biggest challenges to reaching the next generation of high-performance computing. One strategy for achieving an exaflop given limited power is hardware overprovisioning. ...
    • EG PGV 2017: Frontmatter 

      Telea, Alexandru; Bennett, Janine (Eurographics Association, 2017)
    • Data Mining Tornadogenesis Precursors 

      Foss, Greg; McGovern, Amy; Potvin, Corey; Abram, Greg; Bowen, Anne; Hulkoti, Neena; Kaul, Arnav (The Eurographics Association, 2016)
      We investigate the value of 3-D visualization to data mining techniques for identifying tornadogenesis precursors in supercell thunderstorm simulations. We've found results will assist defining storm objects extracted and ...
    • A Scalable Streamline Generation Algorithm Via Flux-Based Isocontour Extraction 

      Biswas, Ayan; Strelitz, Richard; Woodring, Jonathan; Chen, Chun-Ming; Shen, Han-Wei (The Eurographics Association, 2016)
      Streamlines are commonly used for visualizing flow fields, but particle-tracing based streamline computation usually does not scale well as the data size and complexity increase. Large flow simulations like global ocean ...
    • Dynamic Work Packages in Parallel Rendering 

      Steiner, David; Paredes, Enrique G.; Eilemann, Stefan; Pajarola, Renato (The Eurographics Association, 2016)
      Interactive visualizations of large-scale datasets can greatly benefit from parallel rendering on a cluster with hardware accelerated graphics by assigning all rendering client nodes a fair amount of work each. However, ...
    • Dynamically Scheduled Region-Based Image Compositing 

      Grosset, A. V. Pascal; Knoll, Aaron; Hansen, Charles (The Eurographics Association, 2016)
      Algorithms for sort-last parallel volume rendering on large distributed memory machines usually divide a dataset equally across all nodes for rendering. Depending on the features that a user wants to see in a dataset, all ...
    • Interacting with Large Distributed Datasets Using Sketch 

      Budiu, Mihai; Isaacs, Rebecca; Murray, Derek; Plotkin, Gordon; Barham, Paul; Al-Kiswany, Samer; Boshmaf, Yazan; Luo, Qingzhou; Andoni, Alexandr (The Eurographics Association, 2016)
      We present Sketch, a library and a distributed runtime for building interactive tools for exploring large datasets, distributed across multiple machines. We have built several applications using Sketch; here we describe a ...
    • High-Performance Mesh Partitioning and Ghost Cell Generation for Visualization Software 

      Biddiscombe, John (The Eurographics Association, 2016)
      Post-processing large datasets efficiently in parallel requires good load balancing of geometry supplied to the visualization pipeline. When datasets are not pre-partitioned or cannot be read back from simulation output ...
    • Web-enabled Server-based and Distributed Real-time Ray-Tracing 

      Tamm, Georg; Slusallek, Philipp (The Eurographics Association, 2016)
      As browsers expand their functionality, they continuously act as a platform for portable application development within a web page. To bring interactive 3D graphics closer to the web developer, frameworks allowing a ...
    • External Facelist Calculation with Data-Parallel Primitives 

      Lessley, Brenton; Binyahib, Roba; Maynard, Robert; Childs, Hank (The Eurographics Association, 2016)
      External facelist calculation on three-dimensional unstructured meshes is used in scientific visualization libraries to efficiently render the results of operations such as clipping, interval volumes, and material boundaries. ...
    • Parallel Spatial Splits in Bounding Volume Hierarchies 

      Fuetterling, Valentin; Lojewski, Carsten; Pfreundt, Franz-Josef; Ebert, Achim (The Eurographics Association, 2016)
      Bounding volume hierarchies (BVH) are essential for efficient ray tracing. In time-constrained situations such as real-time or large model visualization, fast construction of BVHs usually compromises hierarchy quality, ...
