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…
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…
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…
