Perceptually-motivated, Interactive Rendering and Editing of Global Illumination
(Universitaet des Saarlands, 22.12.2009)
This thesis proposes several new perceptually-motivated techniques to synthesize, edit and enhance depiction of three-dimensional virtual scenes. Finding algorithmsthat fit the perceptually economic middle ground between ...
Proxy-guided Image-based Rendering for Mobile Devices
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
VR headsets and hand-held devices are not powerful enough to render complex scenes in real-time. A server can take on the rendering task, but network latency prohibits a good user experience. We present a new image-based ...
Efficient Multi-image Correspondences for On-line Light Field Video Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Light field videos express the entire visual information of an animated scene, but their shear size typically makes capture, processing and display an off-line process, i. e., time between initial capture and final display ...
Projective Blue‐Noise Sampling
(Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
We propose projective blue‐noise patterns that retain their blue‐noise characteristics when undergoing one or multiple projections onto lower dimensional subspaces. These patterns are produced by extending existing methods, ...
Learning to Predict Image-based Rendering Artifacts with Respect to a Hidden Reference Image
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Image metrics predict the perceived per-pixel difference between a reference image and its degraded (e. g., re-rendered) version. In several important applications, the reference image is not available and image metrics ...
Distortion-Free Displacement Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Displacement mapping is routinely used to add geometric details in a fast and easy-to-control way, both in offline rendering as well as recently in interactive applications such as games. However, it went largely unnoticed ...
Deep-learning the Latent Space of Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We suggest a method to directly deep-learn light transport, i. e., the mapping from a 3D geometry-illumination-material configuration to a shaded 2D image. While many previous learning methods have employed 2D convolutional ...
The Bounced Z-buffer for Indirect Visibility
(The Eurographics Association, 2015)
Synthesizing images of animated scenes with indirect illumination and glossy materials at interactive frame rates commonly ignores indirect shadows. In this work we extend a class of indirect lighting algorithms that splat ...
Real-time Novel-view Synthesis for Volume Rendering Using a Piecewise-analytic Representation
(The Eurographics Association, 2016)
Novel-view synthesis can be used to hide latency in a real-time remote rendering setup, to increase frame rate or to produce advanced visual effects such as depth-of-field or motion blur in volumes or stereo and light field ...
Deep Screen Space for Indirect Lighting of Volumes
(The Eurographics Association, 2014)
We present a method to render approximate indirect light transport from surfaces to volumes which is fully dynamic with respect to geometry, the medium and the main light sources, running at interactive speed. This is ...
