Beyond ExaBricks: GPU Volume Path Tracing of AMR Data
Stefan Zellmann, Qi Wu, Alper Sahistan +2
Adaptive Mesh Refinement (AMR) is becoming a prevalent data representation for scientific visualization. Resulting from large fluid mechanics simulations, the data is usually cell…
GPU-based Data-parallel Rendering of Large, Unstructured, and Non-convexly Partitioned Data
Alper Sahistan, Serkan Demirci, Ingo Wald +4
Computational fluid dynamic simulations often produce large clusters of finite elements with non-trivial, non-convex boundaries and uneven distributions among compute nodes, posing…
KiloNeuS: A Versatile Neural Implicit Surface Representation for Real-Time Rendering
Stefano Esposito, Daniele Baieri, Stefan Zellmann +2
NeRF-based techniques fit wide and deep multi-layer perceptrons (MLPs) to a continuous radiance field that can be rendered from any unseen viewpoint. However, the lack of surface a…
Volkit: A Performance-Portable Computer Vision Library for 3D Volumetric Data
Stefan Zellmann, Giovanni Aguirre, Jürgen P. Schulze
We present volkit, an open source library with high performance implementations of image manipulation and computer vision algorithms that focus on 3D volumetric representations. Vo…
Point Containment Queries on Ray Tracing Cores for AMR Flow Visualization
Stefan Zellmann, Daniel Seifried, Nate Morrical +5
Modern GPUs come with dedicated hardware to perform ray/triangle intersections and bounding volume hierarchy (BVH) traversal. While the primary use case for this hardware is photor…
Successful Common Envelope Ejection and Binary Neutron Star Formation in 3D Hydrodynamics
Jamie A. P. Law-Smith, Rosa Wallace Everson, Enrico Ramirez-Ruiz +10
A binary neutron star merger has been observed in a multi-messenger detection of gravitational wave (GW) and electromagnetic (EM) radiation. Binary neutron stars that merge within…
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…
Accelerating Force-Directed Graph Drawing with RT Cores
Stefan Zellmann, Martin Weier, Ingo Wald
Graph drawing with spring embedders employs a V x V computation phase over the graph's vertex set to compute repulsive forces. Here, the efficacy of forces diminishes with distance…
Augmenting Image Warping-Based Remote Volume Rendering with Ray Tracing
Stefan Zellmann
We propose an image warping-based remote rendering technique for volumes that decouples the rendering and display phases. Our work builds on prior work that samples the volume on t…
Adding Custom Intersectors to the C++ Ray Tracing Template Library Visionaray
Stefan Zellmann
Most ray tracing libraries allow the user to provide custom functionality that is executed when a potential ray surface interaction was encountered to determine if the interaction…
Comparing Hierarchical Data Structures for Sparse Volume Rendering with Empty Space Skipping
Stefan Zellmann
Empty space skipping can be efficiently implemented with hierarchical data structures such as k-d trees and bounding volume hierarchies. This paper compares several recently publis…
