Capturing Relightable Human Performances under General Uncontrolled Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a novel approach to create relightable free-viewpoint human performances from multi-view video recorded under general uncontrolled and uncalibated illumination.We first capture a multi-view sequence of an actor ...
Compressive Image Reconstruction in Reduced Union of Subspaces
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a new compressed sensing framework for reconstruction of incomplete and possibly noisy images and their higher dimensional variants, e.g. animations and light-fields. The algorithm relies on a learning-based ...
Example-based Interpolation and Synthesis of Bidirectional Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Bidirectional Texture Functions (BTF) have proven to be a well-suited representation for the reproduction of measured real-world surface appearance and provide a high degree of realism. We present an approach for designing ...
Compressed Multiresolution Hierarchies for High-Quality Precomputed Shadows
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
The quality of shadow mapping is traditionally limited by texture resolution. We present a novel lossless compression scheme for high-resolution shadow maps based on precomputed multiresolution hierarchies. Traditional ...
Analytic Rasterization of Curves with Polynomial Filters
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a method of analytically rasterizing shapes that have curved boundaries and linear color gradients using piecewise polynomial prefilters. By transforming the convolution of filters with the image from an integral ...
Partitioned Shadow Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Real-time shadows remain a challenging problem in computer graphics. In this context, shadow algorithms generally rely either on shadow mapping or shadow volumes. This paper rediscovers an old class of algorithms that build ...
BRDF Importance Sampling for Linear Lights
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We introduce an efficient method to sample linear lights, i.e. infinitesimally thin cylinders, proportional to projected solid angle. Our method uses inverse function sampling with a specialized iterative procedure that ...
Anatomy-Guided Multi-Level Exploration of Blood Flow in Cerebral Aneurysms
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
For cerebral aneurysms, the ostium, the area of inflow, is an important anatomic landmark, since it separates the pathological vessel deformation from the healthy parent vessel. A better understanding of the inflow ...
Depth of Field Effects for Interactive Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper, a method for interactive direct volume rendering is proposed for computing depth of field effects, which previously were shown to aid observers in depth and size perception of synthetically generated images. ...
Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ...
