Variance and Convergence Analysis of Monte Carlo Line and Segment Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Recently researchers have started employing Monte Carlo-like line sample estimators in rendering, demonstrating dramatic reductions in variance (visible noise) for effects such as soft shadows, defocus blur, and participating ...
Hierarchical Correlation Clustering in Multiple 2D Scalar Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Sets of multiple scalar fields can be used to model many types of variation in data, such as uncertainty in measurements and simulations or time-dependent behavior of scalar quantities. Many structural properties of such ...
Visualizing Multidimensional Data with Order Statistics
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Multidimensional data sets are common in many domains, and dimensionality reduction methods that determine a lower dimensional embedding are widely used for visualizing such data sets. This paper presents a novel method ...
Coupled Fluid Density and Motion from Single Views
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We present a novel method to reconstruct a fluid's 3D density and motion based on just a single sequence of images. This is rendered possible by using powerful physical priors for this strongly under-determined problem. ...
Biorthogonal Wavelet Surface Reconstruction Using Partial Integrations
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We introduce a new biorthogonal wavelet approach to creating a water-tight surface defined by an implicit function, from a finite set of oriented points. Our approach aims at addressing problems with previous wavelet methods ...
Progressive Compression of Arbitrary Textured Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In this paper, we present a progressive compression algorithm for textured surface meshes, which is able to handle polygonal non-manifold meshes as well as discontinuities in the texture mapping. Our method applies iterative ...
GPU-based Polynomial Finite Element Matrix Assembly for Simplex Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
In this paper, we present a matrix assembly technique for arbitrary polynomial order finite element simulations on simplex meshes for graphics processing units (GPU). Compared to the current state of the art in GPU-based ...
A Subspace Method for Fast Locally Injective Harmonic Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a fast algorithm for low-distortion locally injective harmonic mappings of genus 0 triangle meshes with and without cone singularities. The algorithm consists of two portions, a linear subspace analysis and ...
Towards Robust Direction Invariance in Character Animation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In character animation, direction invariance is a desirable property. That is, a pose facing north and the same pose facing south are considered the same; a character that can walk to the north is expected to be able to ...
Combining Point and Line Samples for Direct Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We develop a unified framework for combining point and line samples in direct lighting calculations. While line samples have proven beneficial in a variety of rendering contexts, their application in direct lighting has ...
