Augmenting Image Warping-Based Remote Volume Rendering with Ray Tracing

1 code implementation25 Jun 2020 Stefan Zellmann

We propose an image warping-based remote rendering technique for volumes that decouples the rendering and display phases.

Ray Tracing Structured AMR Data Using ExaBricks

1 code implementation7 Sep 2020 Ingo Wald, Stefan Zellmann, Will Usher, Nate Morrical, Ulrich Lang, Valerio Pascucci

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 representations used by scientific simulations; however, efficiently rendering such data remains a challenge.

KiloNeuS: A Versatile Neural Implicit Surface Representation for Real-Time Rendering

no code implementations22 Jun 2022 Stefano Esposito, Daniele Baieri, Stefan Zellmann, André Hinkenjann, Emanuele Rodolà

NeRF-based techniques fit wide and deep multi-layer perceptrons (MLPs) to a continuous radiance field that can be rendered from any unseen viewpoint.

Visual Analysis of Large Multi-Field AMR Data on GPUs Using Interactive Volume Lines

no code implementations20 Jun 2023 Stefan Zellmann, Serkan Demirci, Uğur Güdükbay

To visually compare ensembles of volumes, dynamic volume lines (DVLs) represent each ensemble member as a 1D polyline.
