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 ... -
SIMD Parallel Ray Tracing of Homogeneous Polyhedral Grids
(The Eurographics Association, 2015)Efficient visualization of unstructured data is vital for domain scientists, yet is often impeded by techniques which rely on intermediate representations that consume time and memory, require resampling data, or inefficient ... -
Simulation of Radio Wave Propagation by Beam Tracing
(The Eurographics Association, 2009)Beam tracing can be used for solving global illumination problems. It is an efficient algorithm, and performs very well when implemented on the GPU. This allows us to apply the algorithm in a novel way to the problem of ... -
Sorted Pipeline Image Composition
(The Eurographics Association, 2006)The core advantage of sort last rendering is the theoretical nearly linear scalability in the number of rendering nodes, which makes it very attractive for very large polygonal and volumetric models. The disadvantage of ... -
A Space-Efficient Method for Navigable Ensemble Analysis and Visualization
(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 ... -
Statistical Analysis of Parallel Data Uploading using OpenGL
(The Eurographics Association, 2019)Modern real-time visualizations of large-scale datasets require constant high frame rates while their datasets might exceed the available graphics memory. This requires sophisticated upload strategies from host memory to ... -
