Scalable Ray Tracing Using the Distributed FrameBuffer
Will Usher, Ingo Wald, Jefferson Amstutz +3
Image- and data-parallel rendering across multiple nodes on high-performance computing systems is widely used in visualization to provide higher frame rates, support large data set…
A Novel Tree Visualization to Guide Interactive Exploration of Multi-dimensional Topological Hierarchies
Yarden Livnat, Dan Maljovec, Attila Gyulassy +2
Understanding the response of an output variable to multi-dimensional inputs lies at the heart of many data exploration endeavours. Topology-based methods, in particular Morse theo…
Towards replacing physical testing of granular materials with a Topology-based Model
Aniketh Venkat, Attila Gyulassy, Graham Kosiba +5
In the study of packed granular materials, the performance of a sample (e.g., the detonation of a high-energy explosive) often correlates to measurements of a fluid flowing through…
NViSII: A Scriptable Tool for Photorealistic Image Generation
Nathan Morrical, Jonathan Tremblay, Yunzhi Lin +4
We present a Python-based renderer built on NVIDIA's OptiX ray tracing engine and the OptiX AI denoiser, designed to generate high-quality synthetic images for research in computer…
Blueprint: Cyberinfrastructure Center of Excellence
Ewa Deelman, Anirban Mandal, Angela P. Murillo +15
In 2018, NSF funded an effort to pilot a Cyberinfrastructure Center of Excellence (CI CoE or Center) that would serve the cyberinfrastructure (CI) needs of the NSF Major Facilities…
A Virtual Frame Buffer Abstraction for Parallel Rendering of Large Tiled Display Walls
Mengjiao Han, Ingo Wald, Will Usher +4
We present dw2, a flexible and easy-to-use software infrastructure for interactive rendering of large tiled display walls. Our library represents the tiled display wall as a single…
Interactive Visualization of Terascale Data in the Browser: Fact or Fiction?
Will Usher, Valerio Pascucci
Information visualization applications have become ubiquitous, in no small part thanks to the ease of wide distribution and deployment to users enabled by the web browser. Scientif…
Ray Tracing Structured AMR Data Using ExaBricks
Ingo Wald, Stefan Zellmann, Will Usher +3
Structured Adaptive Mesh Refinement (Structured AMR) enables simulations to adapt the domain resolution to save computation and storage, and has become one of the dominant data rep…
Improving the Usability of Virtual Reality Neuron Tracing with Topological Elements
Torin McDonald, Will Usher, Nate Morrical +5
Researchers in the field of connectomics are working to reconstruct a map of neural connections in the brain in order to understand at a fundamental level how the brain processes i…
AMM: Adaptive Multilinear Meshes
Harsh Bhatia, Duong Hoang, Nate Morrical +3
Adaptive representations are increasingly indispensable for reducing the in-memory and on-disk footprints of large-scale data. Usual solutions are designed broadly along two themes…
Distributed Resources for the Earth System Grid Advanced Management (DREAM)
Luca Cinquini, Steve Petruzza, Jason Jerome Boutte +9
The DREAM project was funded more than 3 years ago to design and implement a next-generation ESGF (Earth System Grid Federation [1]) architecture which would be suitable for managi…
Digesting the Elephant -- Experiences with Interactive Production Quality Path Tracing of the Moana Island Scene
Ingo Wald, Bruce Cherniak, Will Usher +8
New algorithmic and hardware developments over the past two decades have enabled interactive ray tracing of small to modest sized scenes, and are finding growing popularity in scie…
Uncertainty Visualization of 2D Morse Complex Ensembles Using Statistical Summary Maps
Tushar Athawale, Dan Maljovec, Chris R. Johnson +2
Morse complexes are gradient-based topological descriptors with close connections to Morse theory. They are widely applicable in scientific visualization as they serve as important…
Efficient Space Skipping and Adaptive Sampling of Unstructured Volumes Using Hardware Accelerated Ray Tracing
Nathan Morrical, Will Usher, Ingo Wald +1
Sample based ray marching is an effective method for direct volume rendering of unstructured meshes. However, sampling such meshes remains expensive, and strategies to reduce the n…
Scalable Topological Data Analysis and Visualization for Evaluating Data-Driven Models in Scientific Applications
Shusen Liu, Di Wang, Dan Maljovec +13
With the rapid adoption of machine learning techniques for large-scale applications in science and engineering comes the convergence of two grand challenges in visualization. First…
Rethinking Abstractions for Big Data: Why, Where, How, and What
Mary Hall, Robert M. Kirby, Feifei Li +6
Big data refers to large and complex data sets that, under existing approaches, exceed the capacity and capability of current compute platforms, systems software, analytical tools…
