View-Dependent Adaptive Cloth Simulation
(The Eurographics Association, 2014)
This paper describes a method for view-dependent cloth simulation using dynamically adaptive mesh refinement and coarsening. Given a prescribed camera motion, the method adjusts the criteria controlling refinement to account ...
Topological Reconstruction of Complex 3D Buildings and Automatic Extraction of Levels of Detail
(The Eurographics Association, 2014)
This paper describes a new method allowing to retrieve the indoor and outdoor topology of a detailed 3D building model from its geometry and to extract different levels of detail (LoD) from the resulting topological ...
Extracting and Visualizing Uncertainties in Segmentations from 3D Medical Data
(The Eurographics Association, 2014)
Assessing surfaces of segmentations extracted from 3D image data for medical purposes requires dedicated extraction and visualization methods. In particular, when assessing follow-up cases, the exact volume and confidence ...
Real-Time Deformation of Subdivision Surfaces from Object Collisions
(The Eurographics Association, 2014)
We present a novel real-time approach for fine-scale surface deformations resulting from collisions. Deformations are represented by a high-resolution displacement function. When two objects collide, these offsets are ...
Quantitative Comparison of Hole Filling Methods for 3D Object Search
(The Eurographics Association, 2014)
Retrieval of 3D models has become an important issue due to the increase in the number of digitized objects that are available in many different fields. When stored data present defects such as holes, accurate and reliable ...
GeoTopo: Dynamic 3D Facial Expression Retrieval Using Topological and Geometric Information
(The Eurographics Association, 2014)
Recently, a lot of research has been dedicated to address the problem of facial expression recognition in dynamic sequences of 3D face scans. On the contrary, no research has been conducted on facial expression retrieval ...
Managing Temporal Change of Cities with CityGML
(The Eurographics Association, 2014)
An increasing number of cities are developing digital models. It becomes thus necessary to take into account changes over time. Interoperability and thus the use of standards is also recommended. In this paper, we propose ...
Symmetry and Fourier Descriptor: A Hybrid Feature For NURBS based B-Rep Models Retrieval
(The Eurographics Association, 2014)
As the number of models in 3D databases grows, an efficient 3D models indexing mechanism and a similarity measure to ease model retrieval are necessary. In this paper, we present a query-by-model framework for NURBS based ...
Coulomb Shapes: Using Electrostatic Forces for Deformation-invariant Shape Representation
(The Eurographics Association, 2014)
Canonical shape analysis is a popular method in deformable shape matching, trying to bring the shape into a canonical form that undoes its non-rigid deformations, thus reducing the problem of non-rigid matching into a rigid ...
Adaptive Tetrahedral Meshes for Brittle Fracture Simulation
(The Eurographics Association, 2014)
We present a method for the adaptive simulation of brittle fracture of solid objects based on a novel reversible tetrahedral mesh refinement scheme. The refinement scheme preserves the quality of the input mesh to a large ...
