Discovering structural regularity in 3D geometry

We introduce a computational framework for discovering regular or repeated geometric structures in 3D shapes. We describe and classify possible regular structures and present an effective algorithm for detecting such repeated geometric patterns in point- o ...

Tearing as a test for mechanical characterization of thin adhesive films

Pedro Miguel Nunes Pereira de Almeida Reis

Thin adhesive films have become increasingly important in applications involving packaging, coating or for advertising. Once a film is adhered to a substrate, flaps can be detached by tearing and peeling, but they narrow and collapse in pointy shapes. Simi ...

Totally geodesic subgraphs of the pants complex

Hugo Parlier

In recent work of Brock's, the pants graph is shown to be a combinatorial model for the completion of the Weil-Petersson metric on Teichmuller space. We prove that every Farey graph embedded in the pants graph is totally geodesic, in analogy with the extri ...

Compositional model for predicting multilayer reflectances and transmittances in color reproduction

Mathieu Hébert

The color of materials such as paints, prints and glass may be characterized by a reflectance or a transmittance spectrum. Modeling their reflectance and their transmittance requires describing the interaction of light, from the light source to the observe ...

Laplacian Operator, Diffusion Flow and Active Contour on non-Euclidean Images

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson, Iva Bogdanova Vandergheynst

We propose here some basic approaches to direct processing of the

-images as we take into consideration the geometry of each one. Obviously, the geometry of each of these images is a consequence of the geometry of the sensor's mirror used. This tech ...

Functional, mechanical and geometrical adaptation of the arterial wall of a non-axisymmetric artery in vitro

Nikolaos Stergiopoulos, Paolo Silacci, Martin Zulliger

Vascular remodeling is an adaptive response to variations in the hemodynamic environment acting on the arterial wall. Remodeling translates into changes of structure, geometry and mechanical properties of the artery. Our aim was to study the remodeling res ...

Interactive 3D painting on point-sampled objects

Mark Pauly

We present a novel painting system for 3D objects. In order to overcome parameterization problems of existing applications, we propose a unified sample-based approach to represent geometry and appearance of the 3D object as well as the brush surface. The g ...

Spin interference and Fabry–Pérot resonances in ferromagnet–semiconductor–ferromagnet devices

Dirk Grundler

Magnetoconductance across permalloy/InAs(2DES)/permalloy double junctions in the ballistic limit is examined within the transfer-matrix formalism. We take into account Rashba spin–orbit interaction in the semiconductor as well as oblique modes in devices o ...

Flow Investigation in a Francis Draft Tube : the Flindt Project

François Avellan

The flow investigation in a elbow draft tube is presented. After a review of the existing works related to the flow analysis of such component, the need of an experimental validation of the CFD tools is discussed with respect the practical interest of impr ...

Metropolis light transport for participating media

Mark Pauly

We show how Metropolis light transport can be extended both in the underlying theoretical framework and the algorithmic implementation to incorporate volumetric scattering. We present a generalization of the path integral formulation that handles anisotrop ...
