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…

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…
