Efficient Minimum Distance Computation for Solids of Revolution
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a highly efficient algorithm for computing the minimum distance between two solids of revolution, each of which is defined by a planar cross-section region and a rotation axis. The boundary profile curve for the ... -
An Efficient Transport Estimator for Complex Layered Materials
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Layered materials capture subtle, realistic reflection behaviors that traditional single-layer models lack. Much of this is due to the complex subsurface light transport at the interfaces of - and in the media between - ... -
EUROGRAPHICS 2020: CGF 39-2 Frontmatter
(The Eurographics Association and John Wiley & Sons Ltd., 2020)- -
Expression Packing: As-Few-As-Possible Training Expressions for Blendshape Transfer
(The Eurographics Association and John Wiley & Sons Ltd., 2020)To simplify and accelerate the creation of blendshape rigs, using a template rig is a common procedure, especially during the creation of digital doubles. Blendshape transfer methods facilitate copy and paste functionality ... -
Facial Expression Synthesis using a Global-Local Multilinear Framework
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a practical method to synthesize plausible 3D facial expressions for a particular target subject. The ability to synthesize an entire facial rig from a single neutral expression has a large range of applications ... -
Fast and Robust QEF Minimization using Probabilistic Quadrics
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Error quadrics are a fundamental and powerful building block in many geometry processing algorithms. However, finding the minimizer of a given quadric is in many cases not robust and requires a singular value decomposition ... -
Fast and Robust Stochastic Structural Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Stochastic structural analysis can assess whether a fabricated object will break under real-world conditions. While this approach is powerful, it is also quite slow, which has previously limited its use to coarse resolutions ... -
Fast and Scalable Solvers for the Fluid Pressure Equations with Separating Solid Boundary Conditions
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In this paper, we propose and evaluate fast, scalable approaches for solving the linear complementarity problems (LCP) arising from the fluid pressure equations with separating solid boundary conditions. Specifically, we ... -
Fast Nonlinear Least Squares Optimization of Large-Scale Semi-Sparse Problems
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Many problems in computer graphics and vision can be formulated as a nonlinear least squares optimization problem, for which numerous off-the-shelf solvers are readily available. Depending on the structure of the problem, ... -
Greedy Cut Construction for Parameterizations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a novel method to construct short cuts for parameterizations with low isometric distortion. The algorithm contains two steps: (i) detect feature points, where the distortion is usually concentrated; and (ii) ... -
Illumination-Guided Furniture Layout Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Lighting plays a very important role in interior design. However, in the specific problem of furniture layout recommendation, illumination has been either neglected or addressed with empirical or very simplified solutions. ... -
Interactive Meso-scale Simulation of Skyscapes
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Although an important component of natural scenes, the representation of skyscapes is often relatively simplistic. This can be largely attributed to the complexity of the thermodynamics underpinning cloud evolution and ... -
Interactive Modeling of Cellular Structures on Surfaces with Application to Additive Manufacturing
(The Eurographics Association and John Wiley & Sons Ltd., 2020)The rich and evocative patterns of natural tessellations endow them with an unmistakable artistic appeal and structural properties which are echoed across design, production, and manufacturing. Unfortunately, interactive ... -
Interactively Modifying Compressed Sparse Voxel Representations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Voxels are a popular choice to encode complex geometry. Their regularity makes updates easy and enables random retrieval of values. The main limitation lies in the poor scaling with respect to resolution. Sparse voxel DAGs ... -
Invertible Paradoxic Loop Structures for Transformable Design
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present an interactive tool compatible with existing software (Rhino/Grasshopper) to design ring structures with a paradoxic mobility, which are self-collision-free over the complete motion cycle. Our computational ... -
Local Bases for Model-reduced Smoke Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a flexible model reduction method for simulating incompressible fluids.We derive a novel vector field basis composed of localized basis flows which have simple analytic forms and can be tiled on regular lattices, ... -
Locally Supported Tangential Vector, n-Vector, and Tensor Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We introduce a construction of subspaces of the spaces of tangential vector, n-vector, and tensor fields on surfaces. The resulting subspaces can be used as the basis of fast approximation algorithms for design and processing ... -
Mixing Yarns and Triangles in Cloth Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)This paper presents a method to combine triangle and yarn models in cloth simulation, and hence leverage their best features. The majority of a garment uses a triangle-based model, which reduces the overall computational ... -
Modeling and Estimation of Nonlinear Skin Mechanics for Animated Avatars
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Data-driven models of human avatars have shown very accurate representations of static poses with soft-tissue deformations. However they are not yet capable of precisely representing very nonlinear deformations and highly ... -
Motion Retargetting based on Dilated Convolutions and Skeleton-specific Loss Functions
