Advection-Based Function Matching on Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)A tangent vector field on a surface is the generator of a smooth family of maps from the surface to itself, known as the flow. Given a scalar function on the surface, it can be transported, or advected, by composing it ... -
Complex Transfinite Barycentric Mappings with Similarity Kernels
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Transfinite barycentric kernels are the continuous version of traditional barycentric coordinates and are used to define inter-polants of values given on a smooth planar contour. When the data is two-dimensional, i.e. the ... -
Construction of Topologically Correct and Manifold Isosurfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a simple method to describe the geometry and topologically classify the intersection of level sets of trilinear interpolants with a reference unit cell. The solutions of three quadratic equations are used to ... -
Data-Driven Bending Elasticity Design by Shell Thickness
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a method to design the deformation behavior of 3D printed models by an interactive tool, where the variation of bending elasticity at different regions of a model is realized by a change in shell thickness. Given ... -
Exploration of Empty Space among Spherical Obstacles via Additively Weighted Voronoi Diagram
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Properties of granular materials or molecular structures are often studied on a simple geometric model - a set of 3D balls. If the balls simultaneously change in size by a constant speed, topological properties of the empty ... -
Identifying Style of 3D Shapes using Deep Metric Learning
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a method that expands on previous work in learning human perceived style similarity across objects with different structures and functionalities. Unlike previous approaches that tackle this problem with the help ... -
Incorporating Sharp Features in the General Solid Sweep Framework
(The Eurographics Association and John Wiley & Sons Ltd., 2016)This paper extends a recently proposed robust computational framework for constructing the boundary representation (brep) of the volume swept by a given smooth solid moving along a one parameter family h of rigid motions. ... -
Iterative Closest Conformal Maps between Planar Domains
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Conformal maps between planar domains are an important tool in geometry processing, used for shape deformation and image warping. The Riemann mapping theorem guarantees that there exists a conformal map between any two ... -
Learning 3D Scene Synthesis from Annotated RGB-D Images
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a data-driven method for synthesizing 3D indoor scenes by inserting objects progressively into an initial, possibly, empty scene. Instead of relying on few hundreds of hand-crafted 3D scenes, we take advantage ... -
Mesh Statistics for Robust Curvature Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)While it is usually not difficult to compute principal curvatures of a smooth surface of sufficient differentiability, it is a rather difficult task when only a polygonal approximation of the surface is available, because ... -
Near-Isometric Level Set Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Implicit representations of geometry have found applications in shape modeling, simulation, and other graphics pipelines. These representations, however, do not provide information about the paths of individual points as ... -
Non-Rigid Puzzles
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Shape correspondence is a fundamental problem in computer graphics and vision, with applications in various problems including animation, texture mapping, robotic vision, medical imaging, archaeology and many more. In ... -
Polycube Simplification for Coarse Layouts of Surfaces and Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Representing digital objects with structured meshes that embed a coarse block decomposition is a relevant problem in applications like computer animation, physically-based simulation and Computer Aided Design (CAD). One ... -
Scale-Invariant Directional Alignment of Surface Parametrizations
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Various applications of global surface parametrization benefit from the alignment of parametrization isolines with principal curvature directions. This is particularly true for recent parametrization-based meshing approaches, ... -
Stable Region Correspondences Between Non-Isometric Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We consider the problem of finding meaningful correspondences between 3D models that are related but not necessarily very similar. When the shapes are quite different, a point-to-point map is not always appropriate, so our ...
