Chimera Grids for Water Simulation
(ACM SIGGRAPH / Eurographics Association, 2013)
We introduce a new method for large scale water simulation using Chimera grid embedding, which discretizes space with overlapping Cartesian grids that translate and rotate in order to decompose the domain into different ...
Ray-Traced Collision Detection: Interpenetration Control and Multi-GPU Performance
(The Eurographics Association, 2013)
We proposed in [LGA13] an iterative ray-traced collision detection algorithm (IRTCD) that exploits spatial and temporal coherency and proved to be computationally efficient but at the price of some geometrical approximations ...
Online Reconstruction of Textured Triangle Meshes from Aerial Images
(The Eurographics Association, 2013)
In this paper we present and evaluate a new online reconstruction algorithm to create a textured triangle mesh from a set of aerial images via an unorganized point cloud. Both the point cloud and the mesh are iteratively ...
Indoor Scene Reconstruction using Primitive-driven Space Partitioning and Graph-cut
(The Eurographics Association, 2013)
We present a method for automatic reconstruction of permanent structures of indoor scenes, such as walls, floors and ceilings, from raw point clouds acquired by laser scanners. Our approach employs graph-cut to solve an ...
SHREC'13 Track: Retrieval of Objects Captured with Low-Cost Depth-Sensing Cameras
(The Eurographics Association, 2013)
The SHREC'13 Track: Retrieval of Objects Captured with Low-Cost Depth-Sensing Cameras is a first attempt at evaluating the effectiveness of 3D shape retrieval algorithms in low fidelity model databases, such as the ones ...
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 ...
Schrödinger Operator for Sparse Approximation of 3D Meshes
(The Eurographics Association, 2017)
We introduce a Schrödinger operator for spectral approximation of meshes representing surfaces in 3D. The operator is obtained by modifying the Laplacian with a potential function which defines the rate of oscillation of ...
Computing Extremal Quasiconformal Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Conformal maps are widely used in geometry processing applications. They are smooth, preserve angles, and are locally injective by construction. However, conformal maps do not allow for boundary positions to be prescribed. ...
A Spatio-Temporal Descriptor for Dynamic 3D Facial Expression Retrieval and Recognition
(The Eurographics Association, 2015)
The recent availability of dynamic 3D facial scans has spawned research activity in recognition based on such data. However, the problem of facial expression retrieval based on dynamic 3D facial data has hardly been addressed ...
Functional Maps on Product Manifolds
(The Eurographics Association, 2018)
We consider the tasks of representing, analyzing and manipulating maps between shapes. We model maps as densities over the product manifold of the input shapes; these densities can be treated as scalar functions and therefore ...
