Restricted Power Diagrams on the GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We propose a method to simultaneously decompose a 3D object into power diagram cells and to integrate given functions in each of the obtained simple regions.We offer a novel, highly parallel algorithm that lends itself to ...
Learning and Exploring Motor Skills with Spacetime Bounds
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Equipping characters with diverse motor skills is the current bottleneck of physics-based character animation. We propose a Deep Reinforcement Learning (DRL) framework that enables physics-based characters to learn and ...
Geodesic Distance Computation via Virtual Source Propagation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We present a highly practical, efficient, and versatile approach for computing approximate geodesic distances. The method is designed to operate on triangle meshes and a set of point sources on the surface. We also show ...
ProBGP: Progressive Visual Analytics of Live BGP Updates
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
The global routing network is the backbone of the Internet. However, it is quite vulnerable to attacks that cause major disruptions or routing manipulations. Prior related works have visualized routing path changes with ...
SenVis: Interactive Tensor-based Sensitivity Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Sobol's method is one of the most powerful and widely used frameworks for global sensitivity analysis, and it maps every possible combination of input variables to an associated Sobol index. However, these indices are often ...
Curve Complexity Heuristic KD-trees for Neighborhood-based Exploration of 3D Curves
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We introduce the curve complexity heuristic (CCH), a KD-tree construction strategy for 3D curves, which enables interactive exploration of neighborhoods in dense and large line datasets. It can be applied to searches of ...
Blending of Hyperbolic Closed Curves
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
In recent years, game developers are interested in developing games in the hyperbolic space. Shape blending is one of the fundamental techniques to produce animation and videos games. This paper presents two algorithms for ...
On Landmark Distances in Polygons
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We study the landmark distance function between two points in a simply connected planar polygon. We show that if the polygon vertices are used as landmarks, then the resulting landmark distance function to any given point ...
Orthogonalized Fourier Polynomials for Signal Approximation and Transfer
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We propose a novel approach for the approximation and transfer of signals across 3D shapes. The proposed solution is based on taking pointwise polynomials of the Fourier-like Laplacian eigenbasis, which provides a compact ...
Discrete Optimization for Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We propose a novel discrete solver for optimizing functional map-based energies, including descriptor preservation and promoting structural properties such as area-preservation, bijectivity and Laplacian commutativity among ...
