An Efficient Solution to Structured Optimization Problems using Recursive Matrices
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a linear algebra framework for structured matrices and general optimization problems. The matrices and matrix operations are defined recursively to efficiently capture complex structures and enable advanced ...
Adaptive Temporal Sampling for Volumetric Path Tracing of Medical Data
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Monte-Carlo path tracing techniques can generate stunning visualizations of medical volumetric data. In a clinical context, such renderings turned out to be valuable for communication, education, and diagnosis. Because a ...
Path-Traced Motion Blur using Motion Trees
(The Eurographics Association, 2020)
Motion Blur is an important effect of photo-realistic rendering. Distribution ray tracing can simulate motion blur very well by integrating light, both over the spatial and the temporal domain. However, increasing the ...
Compressed Bounding Volume Hierarchies for Efficient Ray Tracing of Disperse Hair
(The Eurographics Association, 2018)
Ray traced human hair is becoming more and more ubiquitous in photorealistic image synthesis. Despite hierarchical data structures for accelerated ray tracing, performance suffers from the bad separability inherent with ...
SuBloNet: Sparse Super Block Networks for Large Scale Volumetric Fusion
(The Eurographics Association, 2021)
Training and inference of convolutional neural networks (CNNs) on truncated signed distance fields (TSDFs) is a challenging task. Large parts of the scene are usually empty, which makes dense implementations inefficient ...
Visualization Aided Interface Reconstruction
(The Eurographics Association, 2020)
Modern atom probe tomography measurements generate large point clouds of atomic locations in solids. A common analysis task in these datasets is to put the location of specific atom types in relation to crystallographic ...
Proxy Painting
(The Eurographics Association, 2018)
For archaeologists it is often desireable to present statues in their original coloration. With projection mapping real-world surfaces are augmented by digital content to create compelling alterations of the scene's visual ...
Time‐Warped Foveated Rendering for Virtual Reality Headsets
(© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
Rendering in real time for virtual reality headsets with high user immersion is challenging due to strict framerate constraints as well as due to a low tolerance for artefacts. Eye tracking‐based foveated rendering presents ...
Neural Denoising for Path Tracing of Medical Volumetric Data
(ACM, 2020)
In this paper, we transfer machine learning techniques previously applied to denoising surface-only Monte Carlo renderings to path-traced visualizations of medical volumetric data. In the domain of medical imaging, path-traced ...
CPU-Style SIMD Ray Traversal on GPUs
(ACM, 2018)
In this paper we describe and evaluate an implementation of CPUstyle SIMD ray traversal on the GPU. We show how spreading moderately wide BVHs (up to a branching factor of eight) across multiple threads in a warp can improve ...
