Alternative Parameters for On-The-Fly Simplification of MergeTrees
(The Eurographics Association, 2020)Topological simplification of merge trees requires a user specified persistence threshold. As this threshold is based on prior domain knowledge and has an unpredictable relation to output size, its use faces challenges in ... -
Efficient Point Merging Using Data Parallel Techniques
(The Eurographics Association, 2019)We study the problem of merging three-dimensional points that are nearby or coincident. We introduce a fast, efficient approach that uses data parallel techniques for execution in various shared-memory environments. Our ... -
Efficient Sphere Rendering Revisited
(The Eurographics Association, 2023)Glyphs are an intuitive way of displaying the results of atomistic simulations, usually as spheres. Raycasting of camera-aligned billboards is considered the state-of-the-art technique to render large sets of spheres in a ... -
Evaluation of PyTorch as a Data-Parallel Programming API for GPU Volume Rendering
(The Eurographics Association, 2021)Data-parallel programming (DPP) has attracted considerable interest from the visualization community, fostering major software initiatives such as VTK-m. However, there has been relatively little recent investigation of ... -
Faster RTX-Accelerated Empty Space Skipping using Triangulated Active Region Boundary Geometry
(The Eurographics Association, 2021)We describe a technique for GPU and RTX accelerated space skipping of structured volumes that improves on prior work by replacing clustered proxy boxes with a GPU-extracted triangle mesh that bounds the active regions. ... -
A GPU-based Out-of-core Architecture for Interactive Visualization of AMR Time Series Data
(The Eurographics Association, 2023)This paper presents a scalable approach for large-scale Adaptive Mesh Refinement (AMR) time series interactive visualization. We can define AMR data as a dynamic gridding format of cells hierarchically refined from a ... -
High-Quality Rendering of Glyphs Using Hardware-Accelerated Ray Tracing
(The Eurographics Association, 2020)Glyph rendering is an important scientific visualization technique for 3D, time-varying simulation data and for higherdimensional data in general. Though conceptually simple, there are several different challenges when ... -
HyLiPoD: Parallel Particle Advection Via a Hybrid of Lifeline Scheduling and Parallelization-Over-Data
(The Eurographics Association, 2021)Performance characteristics of parallel particle advection algorithms can vary greatly based on workload.With this short paper, we build a new algorithm based on results from a previous bake-off study which evaluated the ... -
Interactive Exploration of Dissipation Element Geometry
(The Eurographics Association, 2017)Dissipation elements (DE) define a geometrical structure for the analysis of small-scale turbulence. Existing analyses based on DEs focus on a statistical treatment of large populations of DEs. In this paper, we propose a ... -
An Interpolation Scheme for VDVP Lagrangian Basis Flows
(The Eurographics Association, 2019)Using the Eulerian paradigm, accurate flow visualization of 3D time-varying data requires a high temporal resolution resulting in large storage requirements. The Lagrangian paradigm has proven to be a viable in situ-based ... -
Machine Learning-Based Autotuning for Parallel Particle Advection
(The Eurographics Association, 2021)Data-parallel particle advection algorithms contain multiple controls that affect their execution characteristics and performance, in particular how often to communicate and how much work to perform between communications. ... -
Massively Parallel Large Scale Inundation Modelling
(The Eurographics Association, 2022)Over the last 20 years, flooding has been the most common natural disaster, accounting for 44.7% of all disasters, affecting about 1.65 billion people worldwide and causing roughly 105 thousand deaths†. In contrast to other ... -
Photo-Guided Exploration of Volume Data Features
(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 ... -
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 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 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 ...
