Efficient Light-Transport Simulation Using Machine Learning
(ETH Zürich, 2019)The goal in this dissertation is the efficient synthesis of photorealistic images on a computer. Currently, by far the most popular approach for photorealistic image synthesis is path tracing, a Monte Carlo simulation of ... -
Generating High-quality 3D Assets from Easy-to-access 2D content
(University College London, 2019-06-28)In the context of content creation, there is an increasing demand for high-quality digital models including object shape, texture, environment illumination, physical properties, etc. As design and pre-view presentations ... -
GPU Data Structures and Code Generation for Modeling, Simulation, and Visualization
(2019-12-16)Virtual prototyping, the iterative process of using computer-aided (CAx) modeling, simulation, and visual-ization tools to optimize prototypes and products before manufacturing the first physical artifact, plays anincreasingly ... -
Lightweight material acquisition using deep learning
(2019-11)Whether it is used for entertainment or industrial design, computer graphics is ever more present in our everyday life. Yet, reproducing a real scene appearance in a virtual environment remains a challenging task, requiring ... -
Locally Solving Linear Systems for Geometry Processing
(2019)Geometry processing algorithms commonly need to solve linear systems involving discrete Laplacians. In many cases this constitutes a central building block of the algorithm and dominates runtime. Usually highly optimized ... -
Model Reduction for Interactive Geometry Processing
(n/a, 2019-04-01)The research field of geometry processing is concerned with the representation, analysis, modeling, simulation and optimization of geometric data. In this thesis, we introduce novel techniques and efficient algorithms for ... -
Model-based human performance capture in outdoor scenes
(2019-05-21)Technologies for motion and performance capture of real actors have enabled the creation of realisticlooking virtual humans through detail and deformation transfer at the cost of extensive manual work and sophisticated ... -
Neighborhood Data Structures, Manifold Properties, and Processing of Point Set Surfaces
(Refubium - Repositorum der Freien Universität Berlin, 2019-07-03)The PhD thesis, titled “Efficient Coordinates for Point Set Surfaces”, is concerned with point sets acquired by 3D acquisition techniques and their processing. The thesis covers and advances both theoretical and applied ... -
Optimal Spatial Registration of SLAM for Augmented Reality
(2019-03-15)Augmented reality (AR) is a paradigm that aims at fusing the perceived real environment of a human with digital information located in 3D space. Typically, virtual 3D graphics are overlayed into the captured images of a ... -
Parametric Procedural Models for 3D Object Retrieval, Classification and Parameterization
(2019-04-05)The amount of 3D objects has grown over the last decades, but we can expect that it will grow much further in the future. 3D objects are also becoming more and more accessible to non-expert users. The growing amount of ... -
Practical Measurement-based Modeling and Rendering of Surface Diffraction
(2019)Computer graphics have evolved at a very fast pace over the last forty years. Most of the research in rendering has been focused on recreating visual effects that can be explained with geometric optics, such as reflections ... -
Quad Meshes as Optimized Architectural Freeform Structures
(2019-10)This thesis tackles the design of freeform surface-like and load-bearing structures realized with cladding panels and supported by a framework substructure, often called gridshells. The actual fabrication of freeform ... -
Revealing the Invisible: On the Extraction of Latent Information from Generalized Image Data
(Universitäts- und Landesbibliothek Bonn, 2020-01-08)The desire to reveal the invisible in order to explain the world around us has been a source of impetus for technological and scientific progress throughout human history. Many of the phenomena that directly affect us ... -
Soft Segmentation of Images
(ETH Zurich, 2019)Realistic editing of photographs requires careful treatment of color mixtures that commonly occur in natural scenes. These color mixtures are typically modeled using soft selection of objects or scene colors. Hence, accurate ... -
Viewpoint-Free Photography for Virtual Reality
(University College London, 2019-07-28)Viewpoint-free photography, i.e., interactively controlling the viewpoint of a photograph after capture, is a standing challenge. In this thesis, we investigate algorithms to enable viewpoint-free photography for virtual ...
