Out-of-Core Framework for QEM-based Mesh Simplification
(The Eurographics Association, 2015)In mesh simplification, in-core based methods using Quadric Error Metric (QEM), which apply a sequence of edge-collapse operations, can generate high-quality meshes while preserving shape features. However, these methods ... -
Visualization of High-Resolution Weather Model Data
(The Eurographics Association, 2015)Significant bottlenecks from I/O required novel techniques be used for a high-resolution severe weather simulation and visualization in the region centered around O'Hare International Airport. The Raytheon Company collaborated ... -
Volume Rendering Via Data-Parallel Primitives
(The Eurographics Association, 2015)Supercomputing designs have recently evolved to include architectures beyond the standard CPU. In response, visualization software must be developed in a manner that obviates the need for porting all visualization algorithms ... -
Packet-Oriented Streamline Tracing on Modern SIMD Architectures
(The Eurographics Association, 2015)The advection of integral lines is an important computational kernel in vector field visualization. We investigate how this kernel can profit from vector (SIMD) extensions in modern CPUs. As a baseline, we formulate a ... -
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 ... -
Visualization Showcase: General-Relativistic Black Hole Visualization
(The Eurographics Association, 2015)Black holes are among the most fascinating and weird objects in the universe. They distort space and time in their close neighborhood in a way that is far beyond our every day experience. We demonstrate the visual effects ... -
Visualization of 2DWave Propagation by Huygens' Principle
(The Eurographics Association, 2015)We present a novel technique to visualize wave propagation in 2D scalar fields. Direct visualization of wave fronts is susceptible to visual clutter and interpretation difficulties due to space-time interference and global ... -
Memory-Efficient On-The-Fly Voxelization of Particle Data
(The Eurographics Association, 2015)In this paper we present a novel GPU-friendly real-time voxelization technique for rendering homogeneous media that is defined by particles, e.g. fluids obtained from particle-based simulations such as Smoothed Particle ... -
Large-Scale Parallel Visualization of Particle-Based Simulations using Point Sprites and Level-Of-Detail
(The Eurographics Association, 2015)Recent large-scale particle-based simulations are generating vast amounts of data posing a challenge to visualization algorithms. One possibility for addressing this challenge is to map particles into a regular grid for ... -

Precomputing Sound Scattering for Structured Surfaces
(The Eurographics Association, 2014)Room acoustic simulations commonly use simple models for sound scattering on surfaces in the scene. However, the continuing increase of available parallel computing power makes it possible to apply more sophisticated models. ... -
Performance Modeling of vl3 Volume Rendering on GPU-Based Clusters
(The Eurographics Association, 2014)This paper presents an analytical model for parallel volume rendering of large datasets using GPU-based clusters. The model is focused on the parallel volume rendering and compositing stages and predicts their performance ... -
Freeprocessing: Transparent in situ Visualization via Data Interception
(The Eurographics Association, 2014)In situ visualization has become a popular method for avoiding the slowest component of many visualization pipelines: reading data from disk. Most previous in situ work has focused on achieving visualization scalability ... -
Auto-Tuning Complex Array Layouts for GPUs
(The Eurographics Association, 2014)The continuing evolution of Graphics Processing Units (GPU) has shown rapid performance increases over the years. But with each new hardware generation, the constraints for programming them efficiently have changed. Programs ... -
Finely-Threaded History-Based Topology Computation
(The Eurographics Association, 2014)Graphics and visualization pipelines often make use of highly parallelized algorithms which transform an input mesh into an output mesh. One example is Marching Cubes, which transforms a voxel grid into a triangle mesh ... -
Parallel Progressive Mesh Editing
(The Eurographics Association, 2014)Highly detailed models are commonly used in computer games and other interactive rendering applications. Intuitive editing methods are thus also required in addition to rendering algorithms. Progressive meshes are often ... -
Clustered Pre-convolved Radiance Caching

Parallel Methodologies for a Micropolygon Renderer
(The Eurographics Association, 2014)This paper compares the performance of three different methodologies for a multi-threaded micropolygon-based renderer. We extend the REYES [AG99] algorithm for multi-threaded rendering, which we call CASCADE. CASCADE ... -
Collaborative High-fidelity Rendering over Peer-to-peer Networks
