Chamber Recognition in Cave Data Sets
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Quantitative analysis of cave systems represented as 3D models is becoming more and more important in the field of cave sciences. One open question is the rigorous identification of chambers in a data set, which has a deep ... -
Diffusion Diagrams: Voronoi Cells and Centroids from Diffusion
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We define Voronoi cells and centroids based on heat diffusion. These heat cells and heat centroids coincide with the common definitions in Euclidean spaces. On curved surfaces they compare favorably with definitions based ... -
Enriching Facial Blendshape Rigs with Physical Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Oftentimes facial animation is created separately from overall body motion. Since convincing facial animation is challenging enough in itself, artists tend to create and edit the face motion in isolation. Or if the face ... -
Fully Spectral Partial Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We propose an efficient procedure for calculating partial dense intrinsic correspondence between deformable shapes performed entirely in the spectral domain. Our technique relies on the recently introduced partial functional ... -
General Point Sampling with Adaptive Density and Correlations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ... -
A GPU-Adapted Structure for Unstructured Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2017)A key advantage of working with structured grids (e.g., images) is the ability to directly tap into the powerful machinery of linear algebra. This is not much so for unstructured grids where intermediate bookkeeping data ... -
Informative Descriptor Preservation via Commutativity for Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We consider the problem of non-rigid shape matching, and specifically the functional maps framework that was recently proposed to find correspondences between shapes. A key step in this framework is to formulate descriptor ... -
Interactive Modeling and Authoring of Climbing Plants
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present a novel system for the interactive modeling of developmental climbing plants with an emphasis on efficient control and plausible physics response. A plant is represented by a set of connected anisotropic particles ... -
kDet: Parallel Constant Time Collision Detection for Polygonal Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We define a novel geometric predicate and a class of objects that enables us to prove a linear bound on the number of intersecting polygon pairs for colliding 3D objects in that class. Our predicate is relevant both in ... -
On Realism of Architectural Procedural Models
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The goal of procedural modeling is to generate realistic content. The realism of this content is typically assessed by qualitatively evaluating a small number of results, or, less frequently, by conducting a user study. ... -
Parallel BVH Construction using Progressive Hierarchical Refinement
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We propose a novel algorithm for construction of bounding volume hierarchies (BVHs) for multi-core CPU architectures. The algorithm constructs the BVH by a divisive top-down approach using a progressively refined cut of ... -
ShapeGenetics: Using Genetic Algorithms for Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In this paper, we show that genetic algorithms (GA) can be used to control the output of procedural modeling algorithms. We propose an efficient way to encode the choices that have to be made during a procedural generation ...
