Robust Iterative Find-Next-Hit Ray Traversal
(The Eurographics Association, 2018)We present two different methods for improving the performance and robustness of ray tracing algorithms that require iterating through multiple successive intersections along the same ray. Our methods do so without ever ... -
A Scalable Cluster-based Parallel Simplification Framework for Height Fields
(The Eurographics Association, 2004)In this paper, we present a method to interactively render 3D large datasets on a PC Cluster. Classical methods use simplification to fill up the gap between such models and graphics card capabilities. Unfortunatelly, ... -
Scalable In Situ Computation of Lagrangian Representations via Local Flow Maps
(The Eurographics Association, 2021)In situ computation of Lagrangian flow maps to enable post hoc time-varying vector field analysis has recently become an active area of research. However, the current literature is largely limited to theoretical settings ... -
Scalable Parallel Feature Extraction and Tracking for Large Time-varying 3D Volume Data
(The Eurographics Association, 2013)Large-scale time-varying volume data sets can take terabytes to petabytes of storage space to store and process. One promising approach is to process the data in parallel, and then extract and analyze only features of ... -
Scalable Parallel Flow Visualization Using 3D Line Integral Convolution for Large Scale Unstructured Simulation Data
(The Eurographics Association, 2019)To address the need of highly efficient and scalable parallel flow visualization methods, we developed a flow visualization system for large unstructured simulation data using parallel 3D line integral convolution (LIC). ... -
A Scalable Parallel Force-Directed Graph Layout Algorithm
(The Eurographics Association, 2008)Understanding the structure, dynamics, and evolution of large graphs is becoming increasingly important in a variety of fields. The demand for visual tools to aid in this process is rising accordingly. Yet, many algorithms ... -
Scalable Parallel Out-of-core Terrain Rendering
(The Eurographics Association, 2010)In this paper, we introduce a novel out-of-core parallel and scalable technique for rendering massive terrain datasets. The parallel rendering task decomposition is implemented on top of an existing terrain renderer using ... -
Scalable Seams for Gigapixel Panoramas
(The Eurographics Association, 2013)Gigapixel panoramas are an increasingly popular digital image application. They are often created as a mosaic of smaller images composited into a larger single image. The mosaic acquisition can occur over many hours causing ... -
Scalable Sort-First Parallel Direct Volume Rendering with Dynamic Load Balancing
(The Eurographics Association, 2007)We describe a sort-first algorithm for parallel direct volume rendering on GPUs, with the intent of high scalability in regards to both performance and data set size. We explore three novel techniques for estimating the ... -
A Scalable Streamline Generation Algorithm Via Flux-Based Isocontour Extraction
(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 ... -
A Scalable, Hybrid Scheme for Volume Rendering Massive Data Sets
(The Eurographics Association, 2006)We introduce a parallel, distributed memory algorithm for volume rendering massive data sets. The algorithm's scalability has been demonstrated up to 400 processors, rendering one hundred million unstructured elements in ... -
Screen Partitioning Load Balancing for Parallel Rendering on a Multi-GPU Multi-Display Workstation
(The Eurographics Association, 2019)Commodity workstations with multiple GPUs have been built by engineers and scientists for real-time rendering applications. As a result, a high display resolution can be achieved by connecting each GPU to a display monitor ... -
Self-Scheduled Parallel Isosurfacing using Distributed Span Space on Cell
(The Eurographics Association, 2010)A method designed for fast isosurfacing on Cell platforms is introduced. It well-utilizes limited amounts of local memory by exploiting a block-based span space. Exploitation goes beyond the usual steps of avoiding span ... -
Shift-Based Parallel Image Compositing on InfiniBand TM Fat-Trees
(The Eurographics Association, 2012)Parallel image compositing has been widely studied over the past 20 years, as this is one, if not the most, crucial element in the implementation of a scalable parallel rendering system. Many algorithms have been proposed ... -
